▼ The Kabompo river basin with an area of 72,000 km2, in North-Western Zambia is one of the major tributaries of the upper Zambezi River. Key water resources management problems in the Kabompo include water allocation to agriculture and ecosystems, effects of land-cover change on the flow regime and potential impacts from mine tailing dams. The objectives for the study were to apply Remote Sensing and a GIS based Soil Water Assessment Tool (SWAT) to estimate river discharge for the basin in order to address the water resource management challenges. Because of paucity of observed data in the Kabompo basin, the model primarily depended on remote sensing datasets for calibration and validation. The Kabompo basin was discretized into 177 sub-basins with a total of 1004 hydrological response units. Methodology included the use of a semi-distributed; ArcGIS based Soil Water Assessment Tool (SWAT) software for hydrological modeling. Remote sensing data sets that included weather data, drainage network and slopes, landuse/ land cover and soils were used to create a database for the sub-basins using ArcGIS. The simulated flow from the SWAT model was calibrated with ESA ERS-2 and ENVISAT radar altimetry river stage values converted to discharge. Observed river flow data for six stations over different time periods between 1990 and 2007 were used in validation and uncertainty analysis of the radar altimetry flow data and remotely sensed weather data, respectively.
The model’s results showed good correlation with observed data giving a Nash Sutcliffe coefficient of 0.87 and an R² value of 0.93, after calibration. The simulation results obtained from the model can be used in a number of water resources management activities like water rights, water allocation, and flood warning. The model is able to generate estimated river flow and stage values even for un-gauged streams. It’s also able to simulate long-term data of a wider area including inaccessible locations than conventional hydrological techniques.
It is concluded that remote sensing is a useful tool for estimation of hydrological data where it is lacking or in unguaged and in accessible areas. Its wide use in a country like Zambia should greatly improve water resources management in a number of areas.

▼ For several years the Department of Physical Geography ofthe University of Utrecht has conducted surveys on the
river Allier in France. These surveys always took place during periods of low
discharge because at high or even moderate discharges measurements are impossible. As information on the flow during a flood is important to understand the
river morphology, a flow model of a part of the Allier was made to simulate the flow during a flood. During a survey in the summer of 1998 bathymetric data and flow measurements were collected. With this data a flow model was made and calibrated. The
discharge during the survey was approximately 20 m3Is. During the calibration it became clear that the downstream boundary condition (a water level) could not be generated well. This problem was overcome by moving the boundary to a flow measurement section where the water level for a
discharge of20 m3/s was known. However this left a problem for simulation at higher discharges than 20 m3/s. The influence ofan error in the downstream boundary condition was estimated both numerically as well as with the Bresse approximation. Both methods showed the backwater effect introduced by an error to extent for about 1000 m upstream of the boundary. The magnitude of a water level error however, was shown to decrease rapidly in the upstream direction. To simulate flow during a flood several simulations were made, steady- (with a constant
discharge) and unsteady state (with a varying
discharge). Ten steady state simulations were made, increasing in
discharge from 100 to 1000 m3/s. In the unsteady state run the flood of November 1994 was simulated. The simulations showed the flow mainly to follow the main channel, leading to an inbank flow pattern. The position of the secondary flow cells - where the bend radius of curvature is smallest - also indicated an inbank flow pattern. Velocities up to 4 m/s were found in the main channel leading to very large bed shear stresses. At several places the flow was directed onto the point bars. The bed shear stress magnitude here indicated that large grain sizes could be transported onto the point bars. The differences between the steady state and the unsteady state simulations were small. Although there were some differences the flow pattern and the magnitude of the velocity were the same. This means that for a global impression ofthe flow pattern at a certain
discharge, a steady state simulation is sufficient. This saves a lot of computation time as the unsteady state simulation has a much larger computation time. Armour layers are layers 0 f coarse grains on top of the bed. They were found at several places in the survey area. During the survey a number of the armour layers were sampled. With the aid of the Oak Creek model by Parker (1990) the threshold of motion ofthe grain sizes within these armour layers was estimated. By combining the Oak Creek model and the bed shear stresses from the flow model it was shown that the threshold of motion was exceeded for all grain sizes within the sampled armour layers.…

▼ Dams and altered flow regimes impact riverine fish. In addition to ecological impacts, unpredictable changes in flow influence the ability to access rivers and effectively sample fish populations. Fisheries management practices are often influenced by water regulation and hydropower generation, thus designing distinct methods of monitoring populations in regulated rivers is critical for effective management. Recurrent changes in
river flow also influence behavior of fish inhabiting the flow-regulated portions of rivers, and such individual behavior may ultimately have population-level effects (e.g. fish abundance). I investigated population abundance and movement of smallmouth bass (Micropterus dolomieu) within a regulated portion of the Broad
River, SC, located below a small hydropower dam. In Chapter 1, I developed a novel approach to estimating bass abundance within a 4.2-km section immediately below the dam where fluctuations in
discharge might influence capture efficiency over different sampling days. The number of smallmouth bass was estimated based on mark-recapture data utilizing two gears, angling and electrofishing. The closed population assumption was confirmed using radio telemetry, and closed population capture-mark-recapture models were fit in the Bayesian hierarchical modelling framework with an estimated number of 2,380 bass (95% Credible Interval: 1,578-3,693) over 200 mm TL. Integrating the two gear types into a mark-recapture study can be an effective method for assessing abundance in spatially or temporally heterogeneous habitats where changing conditions can cause variable sampling environments. In Chapter 2, to inform the sampling strategy to detect a temporal trend in bass abundance, I implemented a power analysis comparing the ability to detect a 2.5% or 5% annual declining trend in abundance after 5, 10, and 15 years based on various levels of sampling effort. The primary interest was to optimize the allocation of effort in terms of number of survey occasions within a year and intensity of effort for each survey occasion. Results indicated that increased effort intensity of each survey occasion (e.g. more boats to be used on each survey to increase capture probability) was more important than adding more occasions with lower effort/bass detection levels within each. In general, power increased with the larger decline (5%) and more sampling effort. In the third and final chapter, I evaluated the effects of
river discharge variation on diurnal fish movement every 30 minutes during daylight hours to establish linkage between hydro-power generation and fish behavior. Generalized additive mixed models (GAMMs) suggested that movement distances slightly increased with
river discharge associated with hydro-power generation in winter, but not in summer. The physiological impacts of this altered behavior was not known, but if rapid and major changes in flow magnitude act as a stressor to individual bass, then population-level effects could follow and impact fisheries resources…

▼ Global hydrological models (GHM) can be used in studies on a range of topics related to land surface hydrology. With growing computational power and availability of better input data, efforts have to be made to improve such models in order to use their full potential. Two factors that determine the quality of GHM simulations are meteorological forcing and parameterization of flow characteristics. Question is how model results respond to changes in these features.
In the first part of this study two sources of meteorological input are compared, i.e. the reanalysis products ERA-Interim and MERRA, using a reference dataset (CRU TS2.1). Both the actual variable fields, like precipitation, and GHM output based on the products are analyzed. The model that is used is PCR-GLOBWB. It solves the land surface water balance and has a
river routing module that simulates
discharge and flooding. One of the objectives is to find out which of the reanalysis products is most suitable for further use in this study and in other future research. This turns out to be ERA-Interim, mainly because MERRA suffers from a problem with cloud cover in tropical regions.
The second part of the study consists of a sensitivity analysis, in which the influence of changes in channel and floodplain properties on
river discharge and flooding is investigated. PCR-GLOBWB is run with 36 different sets of parameters. The resulting
discharge and flood extent about the possibilities of improving the model by adjusting them. Comparing the influence of forcing and parameter variations on model performance will tell something about what the focus should be on in future studies on model improvements.

▼ Temperatures strongly affect physical, chemical, and biological processes in rivers and streams. The processes that influence
river temperatures are known across most geographic regions, but the relative importance varies significantly. Little is known about what controls water temperature Arctic rivers, limiting our ability to understand the impacts of climate change. This dissertation addresses this knowledge gap by incorporating field measurements with
river temperature modeling to estimate the relative importance of key factors that affect Arctic
river temperatures. Results indicate that shortwave radiation (e.g., sunlight) and net longwave radiation are significant throughout an Arctic watershed in all flow conditions. In areas where the
river is smaller, however, exchange of water with the riverbed and inputs of water from the landscape become significant under low-flow and high-flow conditions, respectively. Additional field observations and modeling were used to quantify the water and heat exchanges between the
river and the riverbed. These heat exchanges were found to cool the
river and reduce the daily range of temperatures. To better estimate the flow of water from the landscape to the
river, a new method for estimating
river flow was developed using high-resolution aerial imagery. This method allows us to estimate
river flow without depending on field measurements, and presents a potential solution to barriers in performing
river temperature modeling in other parts of the Arctic.

▼ This thesis covers tidal propagation through networks of channels. Such networks are widespread and are often
subject to discordant human and natural interests. First, the effect of a secondary channel on the tides in a main channel is explained with the use of an idealized model and the responsible physical mechanism is uncovered. The secondary channel can both enhance as well as dampen the tide in the landward part of the main channel, depending on its position. Second, it is investigated what the effects of a secondary channel are on nonlinear tidal characteristics such as tidal range and flood-to-ebb ratio. All tidal constituents are affected through the same physical mechanism, which indicates that the secondary channel locally produces a modification to the tide. This modifying wave subsequently propagates through the main channel. Third, the effect of changes in
river discharge and changes to the geometry of a tidal network are investigated. The Yangtze Estuary is used as an example, as this is a characteristic tidal network that experiences strong fluctuations in
river discharge and has been
subject to a manmade alteration of the geometry. Higher
river discharge results in stronger tidal damping of the semi-diurnal tide. Quarter diurnal tides are enhanced due to an enhanced interaction of the semi-diurnal tide and the residual current through quadratic bottom stress. The changes in the geometry of the Yangtze Estuary resulted in a reduction of net water transport through the affected channel of the network, due to a local decrease in
river induced transport and stronger landward tidally induced net water transport. Finally, the effect of dissipation of momentum on tidal flats on tidal velocities is investigated, as well as the effect of exchanging water over a tidal flat between different channels on tidal velocities. Tidal flat area, tidal flat cross-sectional profile and the position of the tidal flats along the channel are important parameters that determine how the momentum sink mechanism influences the tidal velocities, however, the overall effect of momentum sink is small. Exchange of water between channels was modeled for various heights of the connecting tidal flat, which allowed for varying durations of exchange between the channels. Lower levels of the tidal flat tend to enhance the flood-to-ebb velocity ratio, meaning flood dominant situations become more flood dominant and ebb dominant situations become more ebb dominant.

▼ Effective
discharge (Qe) is defined as the
discharge responsible for carrying the most amount of sediment over two or three decades. The first objective of this thesis is to calculate Qe for the middle Trinity
River in Texas. The historic
discharge data from four gaging stations is used to develop flow probability density functions for the analysis. Suspended sediment rating curves are developed using measured concentration while bedload rating curves are calculated. The second objective of this study is to use collected data to explore how calculations of Qe can be made when measurements are not feasible. Results show that effective
discharge for the middle Trinity
River varies from 11,000 cfs to 20,000 cfs, which is significantly smaller than Q1.5 and the bankfull
discharge. Further analysis shows that historic flow data is sufficient for a reasonable estimate of Qe and that measurements of
river geometry, suspended sediment concentration, and bed sediment samples do not change the calculated Qe.

▼ An observational study was conducted from 2013 to 2016
to investigate suspended-sediment transport processes in the
stratified Connecticut
River estuary. Time-series measurements of
velocity and suspended-sediment concentration from the upper
estuary were analyzed to determine the relative importance of
different processes driving sediment flux under highly-variable
river discharge. Results indicate that under high
discharge the
salt intrusion is forced towards the mouth causing large seaward
sediment fluxes throughout the water column. Seaward fluxes are
dominated by mean advection, with some contribution due to tidal
pumping. Under low
discharge the salt intrusion extends to the
upper estuary, advancing as a bottom salinity front during each
flood tide. Stratification and strong velocity shear during the ebb
tide cause the upper and lower water column to become dynamically
decoupled. Sediment flux near the bed is landward throughout the
tidal cycle despite the net seaward depth-integrated flux, and is
almost fully attributed to the mean estuarine circulation.
River
discharge is the primary factor affecting the magnitude and
direction of sediment flux because of its high variability and
direct connection to the salt-wedge dynamics. A generalized
three-phase conceptual model describes suspended-sediment transport
in shallow, stratified estuaries with low trapping efficiencies.
First, fine sediment bypasses the estuary during high
river flows
and exports to the coastal ocean where a portion of this sediment
is temporarily deposited outside the mouth. Second, during low
discharge offshore mud deposits are reworked by wave- and
tidally-driven currents and some sediment is advected back into the
estuary with the advancing salt intrusion that transports sediment
landward. Third, spatial salinity gradients facilitate sediment
transport from the main channel to channel margins, marshes and
off-
river coves where it is retained and deposited long-term, as
demonstrated in prior studies. This re-introduction and trapping of
recycled sediment under low-
discharge conditions can have important
implications for pollutant transport, shoaling of navigation
channels and harbors, and salt marsh accretion in the face of
rising sea levels.

▼ Large-scale
river projects are executed on the Dutch rivers to meet increased flood conveyance standards. Because the projects bring variation to the standardised
river profile, they are expected to induce increased
river dynamics. The consequences are higher dredging costs and more disruption to inland navigation. All
river intervention plans have been optimised to meet the dredging guidelines of Rijkswaterstaat, but it is important not to look at just the cumulative effect of individual projects but also at the combined effect. Furthermore, the dredging volumes are calculated in a deterministic way: the
river discharge is simulated by means of a single representative yearly hydrograph that is repeated for every year in the simulation. The uncertainties in dredging volumes in time and in space are not known this way. Understanding the stochastic response of the required dredging can help the
river manager better attend the hindrance for inland navigation. It will help the
river manager to decide where and how to interfere in the
river system. This study is conducted to determine the increase and uncertainty of the dredging demand on the Waal
River, before and after the execution of the Room for the
River programme. Numerical calculations with a 2D depth averaged Delft3D model are executed to determine the dredging effort and navigability. To include uncertainty in the model response a Monte Carlo Simulation is performed with
discharge variation on the upstream boundary. The simulations conducted in this study show that the increase in dredging is less than can be expected based on the impact assessment studies of the individual
river intervention works in the Room for the
River programme which stresses the need for integrated impact assessment. The stochastic approach shows that the increase is relatively small compared to the uncertainty in dredging, but nevertheless significant, because considerable increases are predicted at locations that are already heavily dredged. The simulations shows that the dredging capacity on the Waal is insufficient to handle sudden large dredging peaks. If a flood event on the Waal is followed by a rapid fall of the
discharge this leads to disruption to navigation for long periods of time. These peaks would require an unrealistically large dredging capacity so
river management will have to consider structural measures to reduce the dredging effort, or to accept a lower quality of navigation. Structural measures are expensive and it is therefore illogical to try to mitigate all dredging work by structural measures. The dredging demand is not distributed evenly along the
river: It is almost permanent at some locations and more sporadic at others. Locations that show structural dredging can be considered for locations to execute structural measures. Such location are predominantly found on the large
river bends in the Boven-Waal. The information acquired from in this study can be used to develop mitigating measures to limit the maintenance dredging effort and the hindrance for…

▼ Changes in the Earth’s climate system do have consequences for the
river discharges. The development of the future climate is uncertain, which causes uncertainty in the future extreme
river discharges. For flood protection considerations, it is important to quantify the climate uncertainties and its effects on extreme
river discharges. In this study the uncertainty in extreme
river discharges due to Climate Change is quantified. The results indicate the uncertainty in
discharge return levels given a specific forcing scenario. Subsequently, the
discharge return levels of the KNMI climate scenarios are compared with the found results for the forcing scenarios. The study also provides the consequences of the uncertainty in
discharge return levels on the design water levels. The results give the uncertainty in the design water level and the additional height in design water level required to take account for this uncertainty.

▼ Ter vergroting van de afvoercapaciteit zullen er in de toekomst door aanleg van nevengeulen langs het rivierengebied nieuwe splitsingspunten ontstaan. Het is daarom belangrijk voldoende voorspellende kennis te hebben van het morfologisch gedrag van deze splitsingspunten. In deze studie staat het l-dimensionale gedrag van de lokale bodemligging t.p.v. splitsingspunten centraal. Bij een splitsingspunt zal de bodemligging zich namelijk stapsgewijs aanpassen aan de nieuwe omstandigheden benedenstrooms. De omvang van deze sprong in de bodemligging is afhankelijk van de geometrie en de in de tijd varierende hydraulische condities ter plaatse. Om tot meer inzicht te komen in het gedrag van bodemsprongen, zijn er in dit rapport meetdata betreffende de splitsingpunten Pannerdensche Kop en IJsselkop geanalyseerd. Op lokaal schaalniveau wordt een splitsingspunt per benedenstroomse riviertak geschematiseerd als een overgangspunt naar een nieuwe rivierbreedte en als een onttrekkingspunt van afvoer en sediment. Hieruit volgt een evenwichtsuitdrukking voor de bodemsprong per riviertak. Tevens is er een relaxatiemodel af te leiden (Sieben, 1999) bestaande uit een gelineariseerde evenwichtsuitdrukking en een uitdrukking voor de morfologische tijdschaal. Met dit model, dat gebaseerd is op een quasi-stationaire rigid-lid benadering, wordt de aanpassing van bodemsprongen in de tijd beschreven. M.b.v. een gevoeligheidsanalyse is de invloed nagegaan van een aantal coefficienten uit de evenwichtsuitdrukking voor de bodemsprong. Het meest opmerkelijk is hierbij de relatie tussen de k-waarde (machtscoefficient afkomstig uit de knooppuntrelatie) en de n-waarde (machtscoefficient afkomstig uit de transportformule van Engelund en Hansen). Vanwege falend limietgedrag voor grote afvoeronttrekkingen heeft k als hypothetische bovengrens de waarde van n. Deze hypothese lijkt enkel van belang te zijn bij splitsingspunten waar de afvoerverdeling sterk kan varieren en dus een extreme waarde aan kan nemen (kan bijvoorbeeld voorkomen bij splitsingspunten t.g.v. nevengeulen). De bovenstaande hypothese lijkt met enkele aannames (afvoerverdeling is afhankelijk van de lokale bodemligging en morfologische tijdschaal is relatiefkort) uitgebreid te kunnen worden tot een stabiliteitsvoorwaarde voor splitsingspunten gebaseerd op een lokaal schaalniveau. Wanneer k kleiner is dan n, is er sprake van een realistische maar instabiele beschrijving van de lokale bodemligging en wanneer k groter is dan n, geeft het model een niet-realistische maar wel stabiele beschrijving. Dit lijkt op de stabiliteitsvoorwaarde gebaseerd op een globaal schaalniveau (Wang, 1993), die luidt dat k groter moet zijn dan n/3 voor een stabiel splitsingspunt. In de datasets met bodempeilingen betreffende de Pannerdensche Kop en de IJsselkop zijn de verschillende bodemsprongen duidelijk terug te vinden. In de lange termijn ontwikkeling van deze bodemsprongen is er tevens een sterke relatie waar te nemen met de hydraulische data. Op basis van jaargemiddelde hydraulische invoer, geeft de…

▼ River discharge is an essential parameter in morphodynamic modelling. It proves to be highly variable in both time and space. In this thesis the impact of the schematisation of time-dependent
discharge series on morphodynamic change is studied. The impact is governed by several factors such as the long-term
discharge statistics, and both short- and long-term sequences of
discharge stages. A variable
river discharge itself does not necessarily result in morphodynamic change. Changes in conveyance area and roughness are dominant sources of bed fluctuations and bed waves. Moreover, backwater dominated segments are
subject to mild fluctuations in the
river bed. The combination of natural variation of hydrological processes in the upstream
river catchment and the absence of a significant correlation among statistical characteristics of subsequent years makes it hard for
river engineers to construct
discharge time series for
river models that simulate morphodynamic development. The limited predictability of future
discharge time series is an important source of uncertainty in model predictions. A way to estimate this uncertainty is by means of a time-consuming Monte Carlo approach, resulting in a mean long-term morphodynamic trend and the associated uncertainty. An alternative method is the application of a deterministic series for which the long-term
discharge statistics are translated into a cycled annual hydrograph (CAH). It is expected to yield similar morphodynamic changes with respect to the mean trend from the Monte Carlo approach without the need for a large number of computations. However, as is demonstrated in this study, the CAH-method lacks in performance in simulating average long-term development and the amplitude of fluctuations in the
river bed, especially at locations where strong sediment transport gradients are experienced. Using a simplified two-dimensional model that represents a locally widened floodplain, the impact of the included bandwidth, short-term and long-term sequences on morphodynamic change is investigated. The aim is to improve the deterministic hydrograph schematisation and to find a more convenient way to get insight into uncertainty in simulated morphodynamics. These findings result in a set of recommendations for future schematisations of
discharge time series in morphodynamic
river models. An improved deterministic approach is proposed. Using historical measurements of daily
discharge data, years with a similar statistical maximum, mean and standard deviation can be classified. The classified years are translated into multiple cycled annual hydrographs (MCAH). By using these hydrographs, synthetic time series are constructed. Compared to the CAH-approach, the proposed MCAH-method yields a significant reduction of the root mean square error with respect to the long-term average morphodynamic trend from the Monte Carlo simulations. Moreover, the MCAH-series result in amplitudes of bed fluctuations that are closer to the response to natural
discharge time series. Finally, the MCAH-series…

▼ The reserves of fresh water on the earth are of
critical environmental and social importance. The great mass of
liquid freshwater, which is readily accessible to human beings,
resides in major surface stocks such as lakes, ponds, and
reservoirs. Unfortunately, because of the extensive distribution
and dynamic nature of global surface water bodies, our knowledge of
the accurate extent, quantity, and quality of global lake systems
remains surprisingly poor.
River flow and storage in
lakes/reservoirs are two main surface water resources for human
societies. When
river flow experiences high stress due to
increasing human water demand, water storage in lakes and
reservoirs can provide fresh water to mitigate the stress of
river
flow. Therefore, how
river flow and lake water storage are
distributed across the continental surface and what is the balance
between them are crucially important.
The overarching objective of
this thesis is to improve the understanding of the physical
abundance of surface water in lakes and reservoirs. This goal was
achieved by answering four specific questions: 1. Distribution:
Where are freshwater lakes, and where are saline lakes? 2.
Abundance: How many freshwater lakes and saline lakes populate
across the Earth’s surface, and how much area do they cover? 3.
Storage: What are the total water storages in freshwater and saline
lakes? 4. Storage versus flows: What is the spatial contrast
between surface
river flow and lake storage?
The question related
to the distribution and the abundance of global freshwater and
saline lakes was answered by integrating hydrological, spectral,
climatological, and literature evidence on various geographic
settings. I systematically classified global lakes and reservoirs
into freshwater and saline categories from a high-resolution
circa-2000 lake dataset that documents perennial water bodies
greater than 0.4 hectares (Sheng et al., 2015; Sheng et al., 2016).
In order to understand the storage of global lakes/reservoirs, I
then estimated the mean depth, volume, and associated uncertainties
for each lake/reservoir using geo-statistics, GIS-based terrain
analysis, and existing literature. To understand the change of the
distribution and the abundance of global lakes during recent 15
years, attributes of each inventoried lake were updated on the
recently-produced circa-2015 dataset (Sheng et al., 2015; Sheng et
al., 2016) based on the results of freshwater/saline classification
and storage estimation for circa 2000. To explore the spatial
contrast between lake storage and
river flow, which are two major
surface water recourses for human society, the lake storage of
circa-2000 and the average annual
discharge during 1990–2010
simulated by the PCRaster Global Water Balance (PCR-GLOBWB)
hydrological model were compared on the spatial scales of both
individual drainage basins and 0.1° geographic grid.
This research
improves our understanding of water abundance in global lakes and
reservoirs by providing their freshwater/saline classification,
number and storage…

▼ Whether justified by economic, environmental, or socio-cultural ends, there is a strong imperative for thoughtful management of freshwater resources. Meeting this need requires a framework for river management decisions that is transparent,
fair, repeatable, and capable of explicitly stating trade-offs. Although the importance of “environmental” or “instream” flows is widely acknowledged, challenges arise in specifically identifying what flow regime is needed to obtain a desired ecological
state. Taken as a whole, this dissertation sought to inform environmental flow decision making in the Middle Oconee River near Athens, Georgia. Operated by a four-county authority, Bear Creek Reservoir is an off-channel, pump-storage reservoir, which
withdraws water from the Middle Oconee River for municipal water supply. This dissertation applied a structured decision making framework to examine some of the economic and ecological trade-offs associated with alternative pumping schemes. In
particular, the collective body of this dissertation addressed a single question: How can the water authority withdraw water from the Middle Oconee River with the least ecological impact? Rather than recommending a flow regime, my goal was to inform
decision-makers of the advantages and disadvantages of alternative withdrawal schemes. To do so, I developed a variety of techniques which incorporate novel dimensions not commonly addressed in environmental flow decisions (e.g., data visualization,
hydrologic simulation, effectiveness analysis, value-laden decisions). As applied to the Middle Oconee River, these analyses indicate that current regulatory and management approaches are consistently outcompeted by novel environmental flow schemes
relative to both withdrawal volumes and ecological endpoints of hydrologic similarity, fish recruitment, sediment transport, and organic matter transport. Although developed in the context of a single river, this dissertation provided a structured and
rational approach which is broadly applicable to informing environmental flow decision making.

▼ This report describes the development of an outfall structure in Panama City. At this location a Matasnillo river enters the bay along the Cinta Costera. Since this river is polluted it causes a bad water environment and smell at the river mouth area such that it is unable for recreation. Boskalis wants to improve the area in co-operation with local authorities. To do so a solution had to be found for the problems caused by the river, while the peak river discharge during rainstorms will not cause flooding in the area. Several concept designs were developed and in the end a hybrid design, consisting out of an outfall pipeline and culvert, was selected as most viable solution. This design discharges the polluted water through the outfall pipelines several kilometers offshore. During rainstorm events the surplus in river discharge is discharged through the culvert structure. The design is substantiated by functional and structural design calculations. In the end a cost analysis was made.

▼ The Early Eocene Sunnyside Delta interval of the middle Green
River Formation in the Uinta Basin changes from fluvial channel and floodplain deposits to interbedded fluvial, deltaic, and lacustrine deposits across 20 km in the Nine Mile Canyon. Outcrop measured sections and photomosaics with GPS survey of excellent cliff face exposures are integrated with areal mapping of channel dimensions, channel to floodplain ratio, and sedimentary facies variability. This study identifies the Sunnyside Delta interval as a fluvial fan system, composed of variable
discharge river and floodplain deposits that basinward transitions into deltaic, mixed and lake facies. Variable
discharge signatures include the abundant Froude supercritical flow and high deposition rate sedimentary structures, in-channel mudstones, in-channel bioturbation and desiccation, and the low abundance of cross stratification. This work identifies upstream and downstream bar-scale (macroform) accretion styles that were not previously recognized, as variable
discharge river macroforms are commonly referred to as poorly developed or even non-existent. This work identifies low angle downstream dipping accretion, steep upstream accretion, and vertical aggradation as some of the characteristic accretion styles. The fluvial fan stratigraphy is characterized by multiple scales of upward sandying and thickening successions with upward increasing channel to floodplain ratio, channel size, the degree of channel amalgamation, and the proportion of floodplain splay sandstones. The smallest scale upward sandying and thickening successions is recognized as avulsion packages that form the building blocks of the stratigraphy. Larger scale successions are likely to indicate lobe and fan progradation. The common avulsions also determines how the fan interacts with Lake Uinta, as this work documents lateral transitions between channel and floodplain, deltaic and lake facies across just a few hundred meters to a few kilometers. Furthermore, some mouth bar deposits consist of alternating carbonate grainstones and siliciclastic sandstones, and some abandoned channels are filled with dolomitic mudstones. All these transitions indicates a highly irregular shoreline, where fluvial and deltaic deposits build out locally at the active channel locations, laminated dolomitic mudstones accumulate in protected embayments or abandoned channels, and lime grainstones where lake’s wave and current energy is high. We interpret these fluvial-lacustrine interactions in Sunnyside Delta interval as a result of
river avulsions and contemporaneous carbonate productions.

▼ River discharge can affect ocean surface temperature by altering stratification within the oceanic mixed layer. A hitherto unexplored aspect of present climate is the feedback of
river runoff onto climate. This thesis presents an investigation of the impact of global
river runoff on oceans and climate using a fully coupled global climate model, Community Climate System Model (CCSM). Two model simulations for a period of 100 years have been carried out: 1) a reference run (CTRL) that incorporates all the features of a global coupled model with
river runoff into the ocean embedded in it, and 2) a sensitivity run (NoRiv) in which the global
river runoff into the ocean is blocked. Comparison of model climate devoid of fluvial
discharge with the reference run reveals the significance of fluvial
discharge in the present climate.
By the end of 50 years of NoRiv experiment, salinity growth slows down and reaches a quasi-stable state. Regions close to
river mouths exhibited maximum salinity rise that can potentially alter local density and stratification. On an average, denser and saltier waters in the NoRiv run annihilate barrier layer and form a deeper mixed layer, compared to CTRL run. Density gradient created by the modulation in salinity set forth anomalous currents and circulation across coastlines that carries coastal anomalies to open ocean, preventing local salinity buildup. Arctic Ocean, Bay of Bengal, northern high latitude Pacific and the Atlantic are the most affected regions in terms of changes in salinity and temperature. Model simulations demonstrate that major transformation in Arctic freshwater budget can have potential impact on northern Pacific and Atlantic climate. In the absence of runoff, global average sea surface temperature (SST) rise by about ~ 0.5 °C, with major contribution from northern higher latitude oceans. In the Pacific, high latitude warming is related to deepening of mixed layer as well as the northward transport of low latitude warmer waters. Substantial cooling in the central equatorial Pacific (~1 °C during winter) can alter large-scale ocean-atmosphere circulation, including El Niño-Southern Oscillation (ENSO). The reinforcement of Pacific and Atlantic western boundary currents aids the transport of warm saline water from low latitudes to higher latitudes. The results suggest that the
river runoff can have potential impact on oceanic climate.
Response of Indian summer monsoon rainfall to global continental runoff is also examined. In the NoRiv run, average summer monsoon rainfall over India increased by ~ 0.55 mm day−1. Consistent with the increase in annual average Indian monsoon rainfall, all other northern hemispheric monsoon systems showed an increase, while southern hemispheric monsoons weakened. Associated with enhanced monsoon, the periodicity of ENSO in the NoRiv run changes as a result of cooling tendency in the equatorial Pacific, a sign of consistent La Niña. Equatorial Pacific cooling, in spite of a global ocean warming trend, is found to be primarily because of the…

The driving forces behind the flow of water in the recently depoldered area, the ‘Kleine Noordwaard’.

▼ The fieldwork area ‘De Kleine Noordwaard’ is an area that is reopened for rivers and tides (depoldered) as part of the Room for the
River project in the Netherlands. The project is initiated to decrease flood risk along the
river Rhine, by capturing and storing water in the newly created channels and floodplain. The area is being monitored and works as a study and pilot area to find out what happens to a polder when it is given back to nature. It is expected to catch sediment and grow, keeping up with sea level rise. The driving force behind the sediment distribution and deposition in the area is the water flow. The water flow is monitored using H-ADCP’s at both the in- and outlet of the area. Using field data, the data of these H-ADCP’s is used to construct a flow volume balance for the area. Analysis of this flow volume balance shows that the area is mainly functioning as a side channel with a small storage capacity. The water flow through the area is determined by water levels at the up- and downstream boundary of the area, creating a gradient over the area. The gradient in water level over the area is being determined by the
discharge of both the Rhine and the Haringvliet sluices, and transformed by the tidal wave. How much influence the tidal wave has on this gradient depends strongly on the original magnitude of the gradient. High gradients are only slightly changed by the tidal wave while low gradients are suspect to a much larger change. This causes situations at which the water flow through the area is going in the upstream direction instead of the regular downstream direction.

▼ Estuarine morphodynamics are of broad importance to estuaries’ functions related to navigation, human settlement and ecosystems. Inspired by the Yangtze
River estuary (YRE), this study aims to explore the impact of
river discharge, tides and their interaction on long-term estuarine morphodynamics. Use is made of 1D and 2D process-based models.
In first instance we focus on purely hydrodynamic characteristics in a 560 km long basin. We analyze the non-stationary
river tides in the YRE by harmonic analysis and continuous wavelet transformation which reveals a wide range of subtidal variations and non-linear modulation by varying
river discharges. An intermediate
river discharge could be defined at which the amplitudes of the internally generated overtides and compound tides reach maxima.
Based on these hydrodynamic insights we conduct long-term (millennia time scale) morphodynamic simulations in schematized long basins. Vanishing spatial gradients in tidal residual sediment transport indicate an approach towards morphodynamic equilibrium. Morphodynamic equilibrium is also reached in case of a seasonally varying
river discharge, which is reflected by a balance between erosion and accretion during low and high
river discharge periods, respectively.
River flow supplies sediment, accelerates ebb currents, and alters tidal asymmetries. Each of these processes has its own effects on tidal residual transport and morphodynamics. For example, the interaction between a mean flow (i.e., Stokes return flow or
river flow) and tidal currents induces significant tidal residual sediment transport which explains net ebb transport dominance in the presence of a flood tidal asymmetry. A larger
river discharge does not necessarily lead to deeper equilibrium bed profiles. An intermediate
river discharge is found which induces largest residual sediment transport gradients along the estuary leading to deepest equilibrium bed profile. Quantification of this medium
river discharge is case dependent because of the non-linearities involved.
The 2D model approach applied in a large scale fluvio-deltaic system reveal
river, estuarine and deltaic types of morphodynamic features, such as alternating sand bars, meandering channels inside the estuary and more elongated sand bars and distributary channels in the mouth zone and delta. The cross-sectionally averaged depth of the 2D model responds in a similar way to increased
river discharge as a 1D model. Furthermore, a high
river discharge induces ebb transport dominance, restricts development of flood channels and prolongs meander wavelength.
In summary, this research unveils the fundamental effects of tidal asymmetries,
river discharge, and
river-tide interaction in governing residual sediment transport and associated long-term estuarine morphodynamics under combined
river and tidal forcing.

▼ In the northeastern Gulf of Mexico, relating changes in zooplankton communities to environmental factors is crucial to understanding the marine ecosystem and impacts of perturbations such as oil spills on marine ecosystems. Zooplankton samples were collected each year between 2005–2014 in spring and summer in the vicinity of the oil spill (Deepwater Horizon) that occurred in spring 2010. Zooplankton assemblages and environmental conditions significantly differed seasonally, driven by strong variations in zooplankton at continental shelf stations, and by environmental factors including Mississippi River discharge, wind direction, temperature, and chlorophyll concentrations. Total zooplankton abundances were greatest at shelf stations, intermediate at slope stations, and lowest at offshore stations. Seasonal separation was driven by greater abundances of crab zoea, cladocerans, ostracods, and the copepod, Eucalanus spp. during summer. Copepods, Centropages spp., were significant indicators of summer conditions both before and after the oil spill.
Sub-regional comparisons in percent composition and abundances of six major non-copepod and seven copepod taxa revealed that most taxa either remained the same or significantly increased in abundance following the spill. A significant decrease in post oil spill taxa was observed only during spring for total copepods, Eucalanaus spp., and for salps at continental slope stations, however varying processing techniques used for zooplankton before and after the spill were employed and should be considered. . Based on our sampling periods, these results indicate that the 2010 oil spill did not significantly impact zooplankton communities in the northeastern Gulf of Mexico.

▼ A pesquisa teve como objetivo principal estimar o aporte sedimentar em suspensão na baía da Babitonga a partir de um setor de sua área de contribuição hidrográfica, com base em uma análise geomorfológica da relação entre precipitação, relevo e uso da terra. Adotou-se como referências teórico-metodológicas principais os trabalhos de Ab?Saber, sobre os níveis de tratamento para pesquisas em geomorfologia, e de Tricart, que propõe a classificação dos ambientes segundo seu funcionamento ecodinâmico. Efetuou-se em campo monitoramento mensal das vazões dos dez rios que compõem a área da pesquisa e coletas de amostras de água para quantificação de sedimentos em suspensão em laboratório. Os resultados obtidos indicaram um nítido diferencial no comportamento hidrológico e hidrossedimentológico entre as bacias hidrográficas, que se reflete em distintas parcelas de contribuição de cada bacia no aporte sedimentar em suspensão na baía. Estimou-se que são lançadas na Baía da Babitonga, a partir da área da pesquisa, cerca de 7.624 toneladas/ano de sedimentos em suspensão, estando 77,8% deste volume concentrado na foz do Rio Cubatão.
The research had as main goal to estimate the suspended sediment yield into the Babitonga Bay from a sector of its hydrographic contribution area and was based on a geomorphological approach of the relationship among precipitation, relief and land use. The theorical methodological references were the works from Ab?Saber, about treatment levels for geomorphological research, and from Tricart, which proposes environmental classification based on its ecodynamic behavior. Field monitoring of discharge values was accomplished once a month for all ten rivers of the research área, as well as water sample collecting for laboratory suspended sediment quantification. Results indicate a clear distinct hydrological and hydrossedimentological behavior of the watersheds, which reflect the distinguished suspended sediment yield of each individual watershed into the bay. It was estimated that ca. 7,624 year/tons of suspended sediment are introduced into the Babitonga Bay, with 77.8% of that volume concentrated at the Cubatão river estuary.

▼ Le travail de recherche doctorale développé ici vise à améliorer les connaissances et la représentation desprocessus hydro-sédimentaires dans la Rade de Toulon, afin de mettre en place un modèle de dispersion desradionucléides comme outil de gestion post-accidentelle. L’intérêt de cette étude pluridisciplinaire repose surune stratégie qui unit la modélisation et les observations in situ et aborde la problématique complexe descontaminants en milieu marin.Les résultats obtenus permettent de rendre compte de la circulation hydrodynamique dans la Rade de Toulon etde sa forte dépendance au forçage par le vent. Ainsi, les temps d’échange des masses d’eau de la Petite Radesont estimés entre deux et six jours selon les conditions météorologiques. Les mesures en continu réaliséesdans les fleuves Las et Eygoutier ont permis de décrire et de quantifier les apports liquides et solides desbassins versants de la Rade, très peu étudiés jusqu’ici. La Petite Rade représente une zone de sédimentationprivilégiée vis à vis du millier de tonnes par an de matières particulaires apportées par le Las, et apparaît à cetitre comme une zone de piégeage des radionucléides en cas de rejet accidentel.
This doctoral research aims to enhance knowledge of the hydro-sedimentary processes in the Bay of Toulonand to represent these processes through a post accidental managing tool, developed to simulate the dispersionof radionuclides. This work is based on a multidisciplinary strategy, using numerical modelling and in situmeasurements to study the complex problem of contaminants in the marine environment.Hydrodynamic of the Bay and water mass exchanges through the channel have been studied. Results are highlylinked to the atmospheric conditions and the water exchange times of the Little Bay range from two to sixdays, depending on wind conditions. Recorded data in the Las and Eygoutier Rivers led to the description andthe estimation of the catchment yields to the Bay, poorly studied before. With one ton of particulate matterannually discharged by the Las River, the Little Bay seems to be a sedimentation area. In case of accidentalrelease of radionuclides, this area appears to be a trapping zone.

In this work, we examined maximum discharge
probability distributions at the Nemunas river near Kaunas
reservoir during the spring floods in 1921-2010 and their variation
after the construction of Kaunas hydro power plant in 1960. We
determined that the discharge datasets, which were sampled before
and after the construction Kaunas hydro power plant, are not
homogenous and therefore yields substantial variations in the
discharge probabilities. Accumulating effect of Kaunas reservoir
noticeably reduces the arithmetical average, maximum, and
dispersion of the flood discharges. For these reasons, the maximum
flood discharges of the same probability determined by hydrological
calculations near Kaunas reservoir are very different and dependent
on a discharge dataset as well as the chosen calculation
methodology. Based on our results, we provide recommendations to
calculate maximum discharge probabilities of spring
floods.

▼ Large explosive volcanic eruptions inject SO2 into the stratosphere where it is oxidised to sulphate aerosols which reflect sunlight. This causes a reduction in global temperature and precipitation lasting a few years. Here the robust features of this precipitation response are investigated, using superposed epoch analysis that combines results from multiple eruptions. The precipitation response is first analysed using the climate model HadCM3 compared to two gauge based land precipitation datasets. The analysis is then extended to a large suite of state-of-the art climate models participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5). This is the first multi-model study focusing on the precipitation response to volcanoes. The large ensemble allows analysis of a short satellite based dataset which includes ocean coverage. Finally the response of major world rivers to eruptions is examined using historical records. Whilst previous studies focus on the response of just a few rivers or global discharge to single eruptions, here the response of 50 major world rivers is averaged across multiple eruptions. Results are applicable in predicting the precipitation response to future eruptions and to geoengineering schemes that seek to counteract global warming through reducing incoming solar radiation. The main model-simulated features of the precipitation response include a significant global drying over both land and ocean, which is dominated by the wet tropical regions, whilst the dry tropical ocean regions get significantly wetter following eruptions. Monsoon rainfall decreases, whilst in response to individual eruptions the Intertropical Convergence Zone shifts away from the hemisphere with the greater concentration of volcanic aerosols. The ocean precipitation response is longer lived than that over land and correlates with near surface air temperature, whilst the land response correlates with aerosol optical depth and a reduction in land-ocean temperature gradient Many of these modelled features are also seen in observational data, including the decrease in global mean and wet tropical regions precipitation over land and the increase of precipitation over dry tropical ocean regions, all of which are significant in the boreal cold season. The land precipitation response features were robust to choice of dataset. Removing the influence of the El Nino Southern Oscillation (ENSO) reduces the magnitude of the volcanic response, as several recent eruptions coincided with El Nino events. However, results generally remain significant after subtraction of ENSO, at least in the cold season. Over ocean, observed results only match model expectations in the cold season, whilst data are noisy in the warm season. Results are too noisy in both seasons to confirm whether a long ocean precipitation response occurs. Spatial patterns of precipitation response agree well between observational datasets, including a decrease in precipitation over most monsoon regions. A positive North Atlantic Oscillation-like…

▼ Geothermal arsenic (As) and its inorganic species transformation in river systems are of global concern, since As has a potential negative impact on human health and ecosystems. Periods of increased precipitation may change As concentrations and As partitioning in streams, due to elevated water tables, increased runoff generation, dilution, and interactions with sediment.In this study we investigate hydrological conditions of Jemez River, located along the Jemez fault in NM, USA, during the monsoon months June, July and August of 2015. We aim at determining how different hydrological conditions in the Jemez River during the monsoon months might affect the concentrations and riverine mass flows of geothermally derived (total) As and As III discharging in a travertine- and hot spring area called Soda Dam. Water and sediment from the river and hot springs sites, as well as streamflow measurements along a 22 km river reach were collected. The chemical composition of water and sediment was determined using Inductively Coupled Plasma-Optical Emission Spectrometry/Mass Spectrometry (ICP-OES/MS); and Ion Chromatography (IC) as well as a High Performance Liquid Chromatograph (HPLC) coupled to an ICP-MS for further water analysis. Discharge and mass flows as well as element inputs and outputs to/from Soda Dam was computed. The measurement months were characterized by a median discharge of 1642 L/s. During the measurement campaigns peak flows occurred with discharges of 2.5×104 to 6.1×104 L/s during the measurement campaigns. Arsenic concentrations were between 1.3 and 107 μg/L in river water, between 167.3 and 6707 μg/L in hot spring waters, and between 0.37 and 13.1 μg/kg in river bed sediment. Arsenic III was found in hot springs water and river water. Infiltration and subsurface flows induced by fault-associated fractures and permeability structures were found to be likely to divert water at Soda Dam, as reflected in large discharge differences along the reach (470 to 1305 L/s). These flows also had an impact on As concentrations in riverine and hot spring water since they mobilize As from bedrock and sediment. Changing mass flows of As can only in a few cases be explained by dilution processes by Jemez River, which has previously been assumed to be the main control on As mass flows along the stretch. Instead, our findings are likely to reflect changes in chemical composition of the mixed geothermal waters discharging at Soda Dam, due to changing mixing ratios of ground waters of different compositions. The present study hence provides a refined interpretation of the hydrological pathways in Soda Dam and Jemez River, and calls for more discharge and geochemical investigations during a longer study period, to properly investigate the driving forces behind the fate of the As from geothermal fluids.

▼ Rijkswaterstaat and the Dutch contractors have many years of experience in the removal of silt and sand from the Rotterdam harbour. In all those years a great deal of valuable experience has been gained with the behaviour of silt in the harbour. They never succeeded, however in making an estimation/prediction of the amount of sedimentation which has taken place, based on natural parameters like wind
river discharge etc.. In this study an attempt is made to build a Neural Network model in order to perform an adequate simulation. A Neural Network is a powerful nonlinear data analysis tool; the network developed for the sedimentation simulation is called Mud Brain. In order to perform the Neural Network analysis it is necessary to make a re-analysis of the existing measurement data. It is also necessary to make an inventory of the knowledge available about the sediment transport to the Maasmond, starting off with the large scale sediment transports in the Southern North sea. A silt and sand transporting residual-current runs parallel to the Belgian and Dutch shoreline, it is mainly driven by the tide but is strengthened by the ruling wind direction which is from the south-west. Sediment supplied through the Channel and eroded from the Vlaamse Banken travels to the to the Wadden Sea and Oester Gronden. While on transport, sediment sometimes settles under tranquil weather conditions, however, most of the sediment is eroded again and travels further north. Due to the unnatural depth, a great deal of sediment is caught in the Maasmond. The material which enters mostly settles in dredging area F. About 40 % of the material is further transported further along to dredging area E (the buffer pit). In their present state, numerical models are not yet able to predict the amounts of sediment settling in the Maasmond, based on certain natural parameters. The best option for a sediment prediction seems to be a statistical analysis on the relation between the amount of sediment and some natural parameters. For most patterns information about the past as well as information about the present is included (except for the first two patterns which already contain a hitorical time span). In order to provide the statistical analysis with the best possible target outputs, a new sedimentation model is drawn up. This model uses the 1.03-level, the 1.2-level, the amounts of dredged material and some consolidation theory in order to calculate the quantities of sediment, which have settled in a certain dredging area, for every week. This reports presents a test for two statistical methods: 1. Linear regression and 2. Neural Network processing. The Neural Network produces results with a 50 % smaller error margin than the linear regression. The Neural Network results are produced with the so-called 'Leave One Out' testing procedure. This procedure is applied to include all available patterns in the test procedure. After post processing the results of the LOO test fall within an accuracy margin of 23,000 TDS and 34 %. When the standard deviation on…

▼ Mine abandonment and the discharge of contaminated mine water is recognised globally as a major source of surface water and groundwater pollution. Contamination generally arises from the oxidation of sulphide minerals, principally pyrite, by the mining process, and the subsequent chemical reactions can lead to the discharge of mineralised, often acidic, iron, and sulphate rich waters. In many historically mined river catchments, mine water discharge is the main cause of poor water quality. Within the UK, managing the legacy of abandoned mines is one of the principal challenges presented by modern environmental legislation, particularly the EU Water Framework Directive, a challenge that is exacerbated by the diverse and widespread nature of historical mining. The impact and hazard associated with abandoned mining in one of the UK’s most intensively mined regions, the Almond River Catchment, Scotland, was examined via: 1) a detailed GIS mapping and investigation of historical mining processes in the catchment, 2) mine site discharge sampling, 3) detailed site investigations, 4) geochemical modelling of four mine waste sites and 5) analysis of temporal and spatial river water quality in the catchment. The results are then brought together to produce a catchment scale mine water hazard map. Mapping has identified over 300 mine sites in the catchment including coal, oil shale and ironstone mine wastes and flooded coal and oil shale mines. The historical development of oil shale retort methods has been shown to have an impact on potential hazard. Sampling of discharge waters from the different mining activities, in conjunction with detailed mineralogical analysis and geochemical modelling at the four mine waste sites has characterised the main hazards. Ironstone and pyrite bearing coal mine wastes discharge waters with highly elevated Fe and sulphate concentrations, up to 160mgl-1 and 1900mgl-1 respectively, due to extensive pyrite oxidation and acid generating salt dissolution (principally jarosite). Coal mine wastes show variable mineralogy, due to the diverse nature of coal bearing strata, and discharge waters with variable chemistry. Oil Shale mine wastes are generally depleted in pyrite due to historic processing and discharge low sulphate waters with moderately elevated Fe concentrations, up to 5mgl-1. Flooded coal mines discharge sulphate dominant alkaline waters, due to the availability of carbonate minerals in the mine complex, with elevated Fe concentrations, up to 50mgl-1, while flooded oil shale mines discharge waters with moderately elevated Fe concentrations, up to 4mgl-1, due to lower pyrite content in mine strata and reduced availability of oxygen related to mine abandonment age. Once in the surface water environment iron and sulphate display significant concentration-flow dependence: iron increases at high flows due to the re-suspension of river bed iron precipitates (Fe(OH)3); sulphate concentrations decrease with increased flow as a result of dilution. Further examination of iron and sulphate loading at…

▼ Regression analyses and delta-lognormal models were used to investigate whether
river discharge and environmental variables significantly affected relative abundance of brown shrimp, <i>Farfantepenaeus aztecus</i>, in the northern Gulf of Mexico. Significant negative relationships were found between mean
river flow during winter and spring months and catch rates (CPUE) off Texas, Louisiana and Mississippi/Alabama. However, during the same months significant positive relationships between CPUE and the variation in mean
river discharge were found for each state. In Texas and Louisiana, delta-lognormal models revealed depth zone was the most significant variable (<i>P</i>≤0.001) in describing distribution, while time of day (<i>P</i>≤0.001) was most significant in describing CPUE and also distribution and CPUE in Mississippi/Alabama. These results suggest that brown shrimp relative abundance is effected by
river discharge, while gulf-wide environmental variables exert no influence, except dissolved oxygen concentrations affecting distribution off Louisiana.
