▼ RESUMEN: En esta tesis se analiza la relación entre los ríos atmosféricos en la costas de Europa y América del Norte y los índices climáticos atmosféricos y oceánicos mas importantes, con el fin de mejorar la predecibilidad a largo plazo. Dichas teleconexiones se analizan utilizando tanto observaciones como múltiples experimentos numéricos, recreando así el carácter probabilístico del sistema climático. Este diseño experimental revela que la conexión entre El Niño–Oscilación del Sur y el número de dichos ríos en otoño e invierno es muy propenso al efecto de la variabilidad interna de la atmósfera, de modo que las conexiones observadas en el pasado no serán válidos en el futuro, ni tampoco proporcionan una fuente de predecibilidad fiable. La Tesis también extiende el estudio a la circulación, temperatura y precipitación en todo el mundo, mostrando que estos resultados generalmente son válidos para el clima en las zonas extratropicales.

▼ Channel networks in the glaciated mountain basins of Coastal and southern interior British Columbia (Ashnola River Basin) offer opportunities for morphometric studies relating the parameters of the flow area (A) - discharge (Q) relationship to readily available channel and basin parameters.
Steady flow conditions in rough channels are approximated by equations of the form A = a[formula omitted]Q[formula omitted] . The parameters, a[formula omitted] and b[formula omitted], vary individually with each channel and are related to channel dimensions; a[formula omitted] = .94 W[formula omitted]·⁴⁷ and b[formula omitted] = .3 W[formula omitted]·¹⁷. These results are independent of climate and under normal conditions give excellent predictions of the Q-A relations for rough channels in both regions.
The systematic variation of channel dimensions within a basin are related to drainage area:W[formula omitted] = 3.7 DA·[formula omitted] for coastal basins and W[formula omitted] = 1.3 DA[formula omitted] for Ashnola basins. The influence of climate is reflected in the constants, with areas of higher precipitation having larger constants. Drainage area can replace W[formula omitted]: a[formula omitted] = 1.74 DA[formula omitted] and b[formula omitted] = .37 DA[formula omitted]. These relations are applicable only within a climatically homogeneous region.
In rough channels the Q-A relations are considered independent of slope, a result of energy dissipation through frequent hydraulic jumps.
The hydromorphological equations developed here are valid only for rough channels where tumbling flow predominates.

▼ Overcoming the challenges posed by weather and climate-related hazards requires a shared understanding among scientists, decision-makers, and the public of what the likely or potential impacts might be so that appropriate actions can be identified. The research presented here contributes toward addressing this challenge in two primary ways. First, I address questions related to the historical role of atmospheric
rivers (ARs) - key drivers of precipitation variability and extremes in many parts of the world - as determinants of ecological and hydrological variability and hazards in the western US. In doing so, I distinguish areas with differing AR-related hazards (e.g., flood-, fire-, snow-related), identify how atmospheric and land-surface drivers of these risks vary across space and time, and highlight a method for comprehensively analyzing hydrologic responses to ARs that allows potential best- and worst- case impacts that might occur for a given storm to be quantified.The second facet of this research focuses on translating information on climate and weather hazards into a form that is useful to local communities. In doing so, I provide guidance on the construction of climate stress tests – scenarios that represent one or more specific examples of disruptive climatic events. By focusing on a very limited set of extreme conditions, stress tests facilitate analyses of the impacts and risks at the level of detail that is necessary to identify specific actions or strategies to address these risks. Although there is a wealth of guidance on the use of scenarios for natural hazards and climate adaptation planning, this guidance typically assumes the use of ‘off-the-shelf’ data or climate model projections, rather than the creation of a customized scenario depicting an extreme event(s) of interest. I address this gap by synthesizing a variety of data sources and analytical techniques that could be used to construct climate stress tests that are customized to end-users’ needs. I further assess the potential advantages and disadvantages of these methods to provide guidance on which might be best suited given an intended application, the stakeholders involved, and the resources available. Finally, I demonstrate the use of these methods in a case study water resources sustainability planning effort in the Truckee and Carson River basins of California and Nevada. Ultimately, this work is intended to provide building blocks with which scientist-stakeholder teams can co-produce their own stress test scenarios for detailed exploration of weather and climate risks of concern.

▼ Larger and more devastating flood events are happening more frequently across the planet, but flooding is a natural occurrence for any river system. It is only due to human modification of the river system, through the removal of natural features and attempts at flood control, that creates flood hazards that cause damage to communities and ecosystems.
Kapiti Coast’s terrain consisted, pre 19th century, of a mixture of dense coastal forests and extensive wetlands. The landscape has and always will be prone to flooding. With the addition of the expressway to the region, making it easier to travel to and from the capital Wellington, it is expected that the population of Kapiti will grow. But biodiversity may get lost, and flooding may become increasingly more frequent. How might new settlers learn to live with flooding and the constant risk that every time it rains it may cause damage to their homes or businesses? Can there be other benefits to floodplain management, such as biodiversity and recreation?
The aim of this research is to investigate and develop strategies to aid in the settlement of floodplains so that biodiversity is improved, allowing people to live with floods and without the fear that flooding may cause damage. Specifically, the design-led research seeks to generate solutions that improve both flood awareness and flood protection along the Waikanae River. The design seeks to allow the river to express its own flow patterns, and then secondly, how settlement will work within that. It can then be a catalyst for settlement of floodplain areas along the edge of the river.
This thesis will explore how ecology, rehabilitation and natural flood protection can be employed amongst an expanding urban context to create a new way of thinking about our
rivers and mitigating the ever pressing issue of flooding.

▼ In an attempt to understand the complex interrelationships between climate, water infrastructure regimes, and water governance this thesis examines relationships between drought and water use in the Jefferson River Basin in southwest Montana. The Jefferson River is one of the three great headwater streams of the Missouri River and is itself comprised of the Beaverhead, Big Hole and Ruby
Rivers, encompassing a substantial drainage basin of 9,532 sq. miles. The Jefferson's unique hydrological position inherently situates the basin "at the end of the line" of water users and flows at its confluence have plummeted to 200 cubic feet per second (cfs) during extreme drought periods, leaving little water in the river to appease appropriators along the river's remaining 80 miles. The Jefferson River (and all of its important tributaries) is highly utilized for agriculture, resulting in chronic dewatering during peak irrigation demand (typically July through mid-September). Persistent water scarcities over the last 15 years have tested the Basin's ability to sustain historic levels of agricultural production and maintain a commercial sports fishery. This thesis provides a resilience assessment of water resources in Jefferson Basin. RA's attempt to conceptualize dynamic interactions between linked social and ecological systems (SES's). Analysis of complex human use systems (SES's) is inherently interdisciplinary and necessitates a mixed methods approach. The RA completed for this thesis integrated physical analyses of the water use system (utilizing GIS, hydrology, climate and demographic data) with a qualitative survey of water stakeholders with the goal of understanding the processes that drive the Jefferson SES and identifying weaknesses that reduce resilience. Over the last 30 years the Jefferson Basin has benefited from a unique subset of water users and natural resource managers that have successfully worked to improve conditions in the face of extreme environmental challenges. This RA found that although it is highly likely that the Jefferson will be challenged by extreme conditions in the future (related to a changing climate), it is also evident that there is potential for the basin to transition into alternate and more resilient regimes.

▼ This study was undertaken to evaluate the occurrence and characteristics of undercut streambanks in forested headwater streams of the Oregon Coast Range. Undercut streambanks and associated reach characteristics were surveyed along 46 sample reaches (each 152 m in length) in 8 streams; all sample reaches occurred in unmanaged forested riparian areas. Drainage areas ranged from 0.3 to 16.6 km
2. At each undercut location length, surface area, volume, low-flow (summertime) volume, and maximum horizontal depth were measured. Individual undercuts had surface areas ranging from 0.3 to 27.7 m
2 with a mean value of 2.6 m
2, and lengths ranging from 1.2 to 15.2 m with a mean value of 5.0 m. The area undercut streambanks ranged from 0.0 to 27.4 m
2 / 100 m of stream, with an average value of 6.5 m
2 / 100 m. The proportion of bankfull channel area undercut ranged from 0.0 to 4.5%, with an average value of 1.1%. Reach length undercut ranged from 0.0 to 23.6%, with an average value of 6.2%. The values reported in this study are approximately mid-range in comparison to characteristics of undercut banks reported in studies from Alaska, Montana, and Wisconsin. The % of reach area covered by undercut streambanks in this study is approximately half of that provided by large woody debris. Outside channel bends had approximately 6 times more undercut streambanks than inside bends or straight sections. Streams having a sinuosity index greater than 1.15 averaged approximately twice as much % surface area undercut than streams having a sinuosity index less than 1.15. Number of undercuts and undercut characteristics were inversely correlated with channel gradient; significant differences occurring among 1%, 2-4%, and 5+% channel gradient classes. Streambanks ranging in height from 1-2 m had a higher occurrence of undercut streambanks than either lower or higher streambanks. Undercut streambanks were 4 times more common in "composite" than "non-composite" streambanks. Undercut characteristics appear to be correlated with valley segment type. Channel widths were, on average, significantly narrower at undercut sites when compared to reach average channel widths. However, it does not appear than width characteristics are a cause of undercutting. Based on field observations it appears that flow obstructions (gravel bars, boulders, large woody debris) have little impact on undercut characteristics. Both at-a-site and reach-level comparisons of undercut bank characteristics showed relatively strong correlations with streamside tree densities. Red alder (Alnus rubra) is the most prevalent species found in Coast Range riparian areas, and the most significant species in explaining reach-level differences in undercut characteristics. Sitka spruce (Picea sitchensis) is less common in riparian zones, but appears to be positively correlated with the proportion of reach area undercut.

▼ High intensity sampling was undertaken to characterize the temporal and spatial
variability of oxidized nitrogen (NO3-N + NO2-N), ammonia-nitrogen (NH3-N), total
dissolved phosphorus, total unfiltered phosphorus and orthophosphorus (PO4-P) from two
adjacent small streams in Western Oregon's Coast Range, Deer Creek (303 ha) and Flynn
Creek (203 ha). Deer Creek has been 39 % clearcut from 1966 to 1987 while, Flynn
Creek has never been logged and remains a "control" watershed for various research
projects. A sequential wet-deposition precipitation sampler was also used to determine
the temporal variability of oxidized-nitrogen, ammonia-nitrogen, total dissolved
phosphorus and orthophosphorus entering a watershed during two storm events.
Samples collected every one hour over a 25 to 26-h period during summer low
flows indicated that oxidized nitrogen, ammonia-nitrogen, total unfiltered phosphorus,
and orthophosphorus remained relatively constant. Total dissolved phosphorus
concentrations were the most variable but did not have a discernible diel pattern.
On a spatial scale, total unfiltered phosphorus and total dissolved phosphorus
remained relatively constant or showed no discernable patterns when sampled over five
250-m intervals on each creek during summer low flow. Oxidized nitrogen and
orthophosphorus concentrations increased on Deer Creek and decreased on Flynn Creek
in an downstream direction. Ammonia-nitrogen concentrations decreased in a
downstream direction on Deer Creek and remained constant on Flynn Creek.
Nutrient constituent concentrations observed during high intensity sampling of
three storm events had a variable response with stream discharge. Oxidized nitrogen
concentration levels collected during the first fall storm appeared to be consistent with
other research that has shown a flush of oxidized nitrogen out of the forest soil profile
during the first fall storm. Sample concentrations from the first sampled storm had a 36 %
decrease in concentration with the falling limb of the first sampled storm on both Deer
Creek and Flynn Creek. Whereas, oxidized nitrogen concentrations had a 9 to 25 %
decrease with an increase in discharge on the two studied creeks and returned to
pre-storm levels with a decrease in discharge during two winter storms. Total unfiltered
phosphorus concentrations had a 90 to 1150 % (0 to 10 fold) increase with a rise in storm
discharge and decreased with the fall in storm discharge depending on the storm event and
creek sampled. Ammonia-nitrogen, total dissolved phosphorus and orthophosphorus
concentrations were not related to changes in discharge.
Precipitation concentrations of oxidized nitrogen and ammonia-nitrogen either had
a variable response or became diluted with an increase in rainfall amounts. The different
responses appear to be related to storm intensity, with greater dilution in higher intensity
storms.
Results from this study indicate that the input and output of nitrogen and
phosphorus into forested streams can be quite variable on…

▼ As part of ongoing research evaluating the baseline conditions of the Shiawassee National
Wildlife Refuge (SNWR), Michigan, prior to a large scale floodplain wetland restoration,
this project focused the variation in phytoplankton and water chemistry; spatially,
seasonally, and hydrologically. During the growing season of 2014, phytoplankton and
water chemistry parameters were surveyed throughout the SNWR and Saginaw River. These
samples were synthesized and data were compared for patterns by season, sample location,
and longitudinal position on the Saginaw River. Phytoplankton and water chemistry were
also compared to hydrologic data including river slope (which served as an indicator of
hydraulic residence time) as well as the occurrence of reverse or stalled flow in the Saginaw
River.
Results indicated that phytoplankton communities in floodplain wetlands, tributaries,
and the main river channel varied significantly by taxonomic composition and abundance, as
did key water chemistry parameters (Total Phosphorus, Nitrate, Total Dissolved Solids).
Additionally, potamoplankton communities in the Saginaw River varied longitudinally,
becoming more abundant, taxonomically rich, and diverse from upstream to downstream.
Prolonged residence times due to low slopes also showed more diverse and abundant
potamoplankton communities with fewer diatoms than times of high slopes. The occurrence
of reverse flow was found to be associated with a homogenizing effect along the course of
the Saginaw River both in terms of biology and water chemistry.

▼ Podostemaceae is a unique family of Angiosperms
comprising rheophytic, herbaceous members with thalloid plant body.
The plants are distributed in the tropical and subtropical fresh
water streams and water falls. The vegetative and reproductive
features of the members of the Podostemaceae in Kerala have been
studied with particular reference to the taxonomy, distribution and
ecological variations. The work is mainly based on an on the spot
study of the plants and observations in the laboratory. Most of the
rivers in Kerala originating from the Western Ghats receive
North-East and South-West monsoon rains. Therefore, the members of
the Podostemaceae thrive well in these rivers. One new species
(Zevlanidium maheshwarii Mathew and Satheesh) and a new combination
[Podostemum munnarense (Nagendran and Arekal) Mathew and Satheesh]
are described. Keys to the genera and species of the Podostemaceae
of Kerala have been prepared. Polv~leurum stvlosum which exhibits
the highest degree of polymorphism has been classified into
different ecotypes on the basis of distinct morphological features.
Ecotypes are suggested for the species Podostemum subulatum too.
Various aspects related to this family have been discussed in
detail.

▼ Arctic
rivers are the dominant pathways for the transport of terrestrial dissolved organic matter (DOM) to the Arctic Ocean, but knowledge of lability, sources, and transformations of organic carbon and nitrogen in Arctic river watersheds is extremely limited. This study uses chemical analyses of enantiomeric amino acids and carbohydrates as biomarkers to investigate the chemical composition and bioavailability of DOM in five major Arctic watersheds. Carbohydrate-based indicators are sensitive to polysaccharide components derived from all plant sources; hydroxyproline and D-amino acids serve as indicators of plant and bacterial nitrogen, respectively. The results show the bioavailability of DOM in Arctic
rivers is strongly correlated with seasonal discharge, vegetation topography, and water residence time. Pulses of bioavailable DOM were observed in the Siberian
Rivers during the spring freshet, whereas the Mackenzie River exhibited extensively degraded DOM throughout all stages of the hydrograph. Freshet samples showed elevated input of plant-derived dissolved organic nitrogen. Bacterial organic matter comprised a significant fraction of riverine DOM (20-40%). These results demonstrate the importance of bacteria in regulating DOM composition and reactivity in Arctic
rivers.

▼ Slimy sculpin (Coitus cognatus) are important inhabits of cold-water streams in southwestern Wisconsin. Unpublished data suggests that small-bodied sculpin are more abundant in stream riffles with high macrophyte cover than those where macrophytes are scarce. The objectives were to determine if the presence of abundant macrophytes affects the density of different size classes of sculpin and those differences were driven by the influence of macrophyte presence oflocal food web structure. Basal carbon sources, macroinvertebrate prey, and slimy sculpin were sampled during the fall in the Coon Creek watershed of Wisconsin, and food webs were constructed using stable isotope analysis. Data were compared between sites with high and low macrophyte abundance. Periphyton biomass and the density and bioinass of common macroinvertebrate families were similar between areas of high and low macrophyte abundance. Slimy sculpin were not segregated by size between these site types, however the total density of slimy sculpin was significantly higher in areas with high macrophyte abundance. Macrophyte abundance influences sculpin distribution by providing refuge from predators and providing greater prey availability. The food webs at sites with abm1dant and scarce macrophyte cover were detritus based. In the fall, aquatic and terrestrial based detritus are important carbon sources in areas with high-macrophyte growth.

▼ As gravel bed
rivers aggrade, they can develop subsurface stratigraphy consisting of heterogeneous grain-size distributions in the downstream, cross-stream, and vertical directions. During subsequent periods of degradation, this heterogeneous stratigraphy can be exhumed and may feedback on the processes that drive morphodynamic evolution. However, these surface-stratigraphy feedbacks are poorly understood and difficult to predict. These feedbacks are investigated by implementing the ability to store, track, and access bed stratigraphy in the 2-dimensional mixed-grain-size morphodynamic model FaSTMECH. The stratigraphy framework consists of a 3-dimensional grid of subsurface layers containing grain size fractions. The active layer (surface) is then allowed to exchange sediment with bedload as well as the stratigraphy layers. During aggradation, size fractions of sediment in the active layer and bedload are mixed with the highest stratigraphy layer size fractions. During degradation, the active layer takes on the sediment properties stored in the stratigraphy. This model is used to investigate stratigraphic feedbacks on the coevolution of surface patchiness and alternate bar morphology. When alternate bars are forced by an obstruction, differences between model simulations with and without stratigraphy enabled are minimal because bars quickly stabilize and become fixed. With no obstruction, however, migrating alternate bars formed with stratigraphy enabled are wider and display stronger sorting patterns than those formed without accounting for stratigraphy. The repeated aggradation and degradation associated with bar migration results in frequent interaction between subsurface and surface material. The repeated access of material finer than the initial bulk material during degradation allows for greater degrees of surface sorting where coarse bar tops become coarser and fine pools become finer. Changes in sorting patterns are shown to increase bar width and increase bar celerity by 1 cm/min. This suggests that surface/subsurface interactions play an important role in setting bed morphology, sorting patterns, and bedform dynamics in gravel bed
rivers.

▼ In 1990, the United States Environmental Protection Agency recommended the use of biological indicators from more than one group of organisms be used to help monitor water quality. Due to the ubiquitous nature and abundance of stream salamanders in small streams, their tendency to maintain small territories and their submersion within their environment, stream salamanders are expected to be good indicators of the water quality of the stream in which they live. They are easily affected by human disturbances including construction, contamination, and surface water runoff and are expected to be indicators of water quality in shallow streams. There are two common stream salamanders found in Connecticut, Eurycea bislineata and Desmognathus fuscus, which were collected during this study. A subset of streams located within the Connecticut Major Basin was sampled for salamanders. Staff from the Connecticut Department of Environmental Protection provided a database with information on water quality parameters, which included a variety of chemical analyses collected over time. These streams were located in areas surrounded by varying land uses that have been identified as wooded, low-density residential, and high-density commercial/urban. Salamander abundance from each sampling location was compared to the data previously collected and provided in the database. Sampling locations were determined using the provided database. Each location was sampled on one day in Fall 2007. Sampling occurred, where possible, in three replicates at each location, beginning in the downstream stretch and working our way upstream with 64 m2 quadrats using four volunteers, working in a counterclockwise, concentric grid. The majority of salamanders were captured within areas of flowing water, since that was the focus of the study. I did not find any significant relationship between the general water quality parameters provided in the database and salamander population abundance during my study. The evidence that one general water chemistry parameter, magnesium, affects salamander population abundance, is weak (p-value 0.066). As a result, this study does not provide evidence that salamanders may be used as indicators of stream condition in Connecticut.

▼ Many urban rivers receive significant inputs of metal-contaminated sediments from their catchments. Their restoration has the potential to increase the deposition and accumulation of these sediments from greater sediment supply and increased channel hydraulic complexity, creating a store of metals which could have negative impacts upon ecosystems and human health. Macrophytes often establish in restored channels and have the potential to stabilise these sediments and uptake metals through processes of phytoremediation, thus reducing the risk of the accumulated sediments becoming a source of metals. This thesis investigates the effects of river restoration upon sedimentation patterns and the interactions between macrophytes and sediments in terms of sediment trapping, stabilisation and metal uptake within urban river systems. At a reach scale, greater finer sediment deposition and the accumulation of sediment around in-channel vegetation was found within restored stretches of tributaries of the River Thames London, reflecting sediment availability and hydraulic conditions. These sediments were important in terms of greater metal storage within stretches, and along with gravels showed particularly high metal concentrations. Interactions between macrophytes, sediment and flow were investigated within the urban-influenced River Blackwater, Surrey. At the stand scale, the common emergent Sparganium erectum was found to significantly reduce flow velocities, accumulate fine sediments and retain them over winter. Research on individual plants revealed that, although three common emergent macrophytes (Sparganium erectum, Typha latifolia and Phalaris arundinacea) did not significantly phytoremediate metal contaminated sediments through metal uptake or bioconcentration, the reinforcement and stabilisation of these accumulated sediments (particularly by Sparganium erectum and Typha latifolia) and the creation of anoxic sediment conditions which strongly bind metals, were important in reducing the risk of metal mobilisation from the sediments. These macrophyte sediment interactions illustrate the great potential of using emergent macrophytes in the restoration and management of urban rivers with metal contaminated sediments.

▼ Braided rivers are complex, fascinating fluvial pattern, which represent the natural state of many gravel and sand bed rivers. Both natural and human causes may force a change in the boundary conditions, and consequently impact the river functionality. Detailed knowledge on the consequent morphological response is important in order to define management strategies which combine different needs, from protection of human activities and infrastructures to preservation of the ecological and biological richness. During the last decades, research has made significant advance to the description of this complex system, thanks to flume investigations, development of new survey techniques and, to a lesser extent, numerical and analytical solutions of mathematical models (e.g. Ashmore, 2013). Despite that, many relevant questions, concerning the braided morphodynamics at different spatial and temporal scales (from the unit process scale, to the reach scale, and eventually to the catchment scale) remain unanswered. For example, quantitative analysis of the morphological response to varying external controls still requires investigation and needs the definition of suitable, stage-independent braiding indicators. In addition, the morphodynamics of the fundamental processes, such as bifurcations, also needs further analysis of the driving mechanisms. General aim of the present study is to develop new methods to exploit, in an integrated way, the potential of the new possibilities offered by advanced monitoring techniques, laboratory models, numerical schemes and analytical solutions. The final goal is to fill some gaps in the present knowledge, which could ultimately provide scientific support to river management policies. We adopted analytical perturbation approaches to solve the two-dimensional shallow water model; we performed laboratory simulations on a large, mobilebed flume; we analysed existing topographic measurements from LiDAR and Terrestrial Laser scanning Devices; and we simulated numerically the river hydrodynamics. Within each of the six, independent, research chapters, we interconnected results from the different approaches and methodologies, in order to take advantage of their potential. Summarising, the more relevant and novel outcomes of the present work can be listed as follows:(i) We explored the morphological changes during a sequence of flood events in a natural braided river (Rees River, NZ) and we proposed a morphological method to assess the sediment transport rate. In particular we propose a semi-automatic method for estimating the particles path-length (Ashmore and Church, 1998) on the basis of the size of the deposition patches, which can be identified on the basis of DEM of differences. Comparison with results of numerical simulation confirmed that such an approach can reproduce the response of the bedload rate to floods of different duration and magnitude. (ii) We developed a new indicator of the reach-scale morphology and, on the basis of existing laboratory experiments, we explored its dependence,…

▼ A hydrodynamic study shows high flow velocities at the IJsselkop bifurcation during the design discharge of 16,000 m3/s. The study, performed in 2005, concludes that these velocities might affect 1) the stability of IJssel river bed and 2) the stability of the grass cover layer of the flood plain at the bifurcation. This report provides a better insight in the behaviour of the river branches at the IJsselkop bifurcation during the design discharge. Furthermore, the likeliness has been studied that these flow velocities influence the stability of both the grass cover layer of the flood plain and the bed of the river IJssel. Additionally, it shows the effect on the discharge distribution at this bifurcation if large scale erosion of the grass cover or IJssel bed occurs. The route of the Rhine river towards the sea has changed several times the last few hundred thousand years. It deposited its sediment on various locations with a variation in sediment size, depending on its river type. The top layer of coarse sediment is located close to the surface in the Eastern part of the Netherlands. Additionally, the supply of coarse material results in a coarse top layer of the river bed around the bifurcation at the IJsselkop. The IJssel river bed top layer consists of coarser material than the Lower Rhine bed as a results of the geometry of the
rivers. The IJssel bed consists of a coarse layer of approximately 1 m thick on top of a layer with finer sediment. The subsoil of the flood plain consists of ‘sandy clay’, which has been determined from stratification data. The level of the IJssel bed decreases with 1 – 2 cm/yr between 2002 and 2013, which is in the same order of magnitude as the decrease in water level. The stability of the IJssel river bed during design discharge has been assessed based on detailed drilling data. Three situations has been analysed for an insight in the behaviour of the river bed. The first situation is initiation of movement based on uniform sediment, which is based on the Shields mobility parameter. The second situation is initiation of movement based on mixed sediment. This is based on the hiding and exposure mechanism, which reduces the stability of the bed material. The third situation includes instantaneous shear stresses that are imposed by the presence of dunes. The analysis showed that a large area of the considered IJssel river bed can be assumed to be unstable during design discharge conditions. The stability of the flood plain has been assessed with a quantitative and qualitative analysis of the stability of the grass cover. A flow at the flood plain directed from West to East, the lateral discharge, is the result of the water level differences between the two branches just downstream of the IJsselkop bifurcation point, caused by the less gentle bed slope of the IJssel river than that of the Lower Rhine. High flow velocities are present at the entire flood plain, except for the Northwest part. The quality of the flood plain depends on the characteristics of the grass cover and clayey…

▼ Previous research spanning lotic, lentic, and marine environments suggests that habitat enhancement structures (HES) may attract and concentrate fish from adjacent habitats rather than increase fish populations. In addition to concentrating fish, we hypothesized that anglers may target HES, and therefore, that fish concentrated at HES may be more susceptible to angling. To test our hypotheses, we assessed spatial patterns of: 1) habitat structure; 2) fish holding locations; and 3) fishing pressure (i.e., casting patterns) in southwestern Montana stream reaches with HES. Findings suggest that HES aggregate fish and that anglers more successfully target fish holding near artificial HES than similar densities of fish holding further from artificial structures (e.g., near natural holding structures). We conclude that installation of HES may increase angling opportunities, but could also act as fish population sinks by focusing fishing pressure over likely fish holding areas.

Poole and Alexander Zale were co-authors of the article, 'Fish and angler use of instream habitat enhancement structures in 'restored' stream reaches' in the journal 'Fisheries' which is contained within this thesis.

▼ In this PhD dissertation research we sought to elucidate stream network biological and physical influences on hydrological and biogeochemical signatures observed along stream networks and at watershed outlets. Our research indicates that stream nutrient uptake and groundwater exchange processes can modify inputs from terrestrial sources and influence the timing and signature of watershed fluxes. We determined that stream nutrient uptake followed Michaelis-Menten kinetics across a broad range of systems and that land use / land cover change can alter stream nutrient uptake magnitudes. Additionally, we found that watershed structure and network geometry exerted strong controls over sourcewater contributions and streamwater compositions along stream networks and at watershed outlets. Combined, this PhD research suggests that uptake kinetics and hydrologic turnover exert strong controls over streamwater composition and sourcewater contributions, and that physical and biological contributions to total nutrient retention and the dynamic and concentration dependent nature of biological uptake combine to control solute and nutrient signatures. We suggest accurate assessment of total retention across stream reaches and stream networks requires quantification of physical retention and the concentration dependent nature of biological uptake, understanding necessary to help mitigate the potentially deleterious influences elevated nutrient export can have on downstream ecosystems.

▼ When exposed at Earth’s surface, rocks are out of
thermodynamic equilibrium with respect to their environment. This
disequilibrium drives the chemical transformation, or weathering,
of these rocks into soils and governs the chemical composition of
natural waters and the atmosphere. Over geologic timescales,
complex feedbacks associated with weathering processes are presumed
to regulate the concentrations of CO₂ and O₂ in the atmosphere with
profound implications for the habitability of the planet. However,
a mechanistic understanding of how biologic, tectonic, and climatic
conditions interact to control weathering fluxes has remained
elusive. In part, our understanding of weathering processes is
hindered by the fact that they operate continuously over an
enormous range of spatial (atomic to global) and temporal
(microseconds to millions of years) scales, but we can only make
measurements over discrete ranges of these values. While each scale
of observation available offers unique insights, it is often
difficult to link observations made at different scales. For my
Ph.D., I focused on three distinct projects that span the range of
observable scales in order to better understand the links between
chemical weathering and long-term biogeochemical cycles. ❧ Chapter
2: Laboratory insights into microbial mineral dissolution. Rocks
and minerals represent a major reservoir of bio-essential
nutrients. While abundant, some of these lithogenic nutrients, like
iron, are not readily bio-available. As a result, many organisms
produce metal-binding ligands to scavenge these trace nutrients
from the environment. Using targeted laboratory experiments with
live microbial cultures and purified microbial ligands, I explored
efficacy by which microbes can access trace nutrients from common
silicate minerals (Torres et al., in prep). In addition to
providing insight into biological nutrient scavenging strategies,
this work also provides the basic research necessary to develop
microbe-based CO₂ sequestration techniques since the dissolution of
silicate minerals for nutrient acquisition also sequesters CO₂. ❧
Chapters 3 & 4: Geomorphic control on the hydrology and carbon
budget of weathering. Erosional processes and hydrology are known
to influence chemical weathering rates by controlling the
timescales over which minerals react. Accurately describing the
complex linkages between weathering, erosion, and hydrology
observed in natural environments remains a major research
challenge. To help address this problem, a major part of my Ph.D.
was focused on characterizing how chemical weathering and hydrology
are coupled in distinct erosional environments. This work combines
hydrologic monitoring, solute chemistry, and water isotope analyses
in order to robustly document how water is stored in catchments and
link this to measured solute fluxes from chemical weathering (Clark
et al., 2014; Torres et al., 2015). The results of this study are
intriguing in that the hydrological control of weathering was found
to vary predictably with the erosional…

▼ My thesis explores landscape and memory as thin places—the meeting places between opposites, particularly between humanity and divinity. My initial poem, “Memory Palace,” both praises the brain’s power and acknowledges its ability to fail, and many of my poems—set on spring-fed river in Florida where I spent much of my childhood—describe both the beauty and terror of the setting in order to portray the complexity of the divine. The speaker of my poems has inherited a devotion to preserving a seeming perfection which, held too tightly, becomes stagnant, even destructive. In “A Chat with Grandfather,” the family’s history starts with a dragon-slayer, but these grand beginnings have not been lived up to over the years, leaving the family in a past-obsessed, diminished state in which they have become the dangerous creatures which the family’s original members fought to destroy. In other poems, the speaker is immobilized by her sister’s depression and by her own loneliness. When these moments of immobility are broken, the speaker moves toward freedom. The suspense is often broken by a physical swallowing—of bringing what’s outside in. “Freediving into the Headspring” ends with such a spell-breaking command: “swallow your fill and breathe.” Many of my poems contain shatterings—a pain that, ultimately, helps the speaker better know herself, her family, and the divine.

▼ Rivers provide many of our day-to-day needs. They allow, for instance, the production of drinking water and the movement of goods via inland waterways. However, river systems experience disturbances, such as droughts and pollution plumes. These disturbances can impair the functioning of river systems and their ability to provide the desired functions and services. Since some of these disturbances have very little impact while other cause many problems, it is important to determine how a river system handles different disturbances. Resilience is often used to indicate and assess the behaviour of systems with regard to disturbances. Using the concept of resilience with regard to river systems can help determine how well river systems handle disturbances. In order to determine how resilient a river system is, a method to assess the resilience of river systems is needed. Research into the resilience of river systems has only been done with regard to flood resilience. This resilience does not consider other disturbances, such as droughts, and therefore does not represent the full resilience of the system. Furthermore, this research often resulted in suggestions and pointers to create and improve resilience, but not in a clear method to help assess it. Hence, the objective of this study was to develop a method to assess the resilience of river systems. In order to create this method several questions need to answered. First, a clear definition of resilience of river systems is needed. For this it should first be determined what resilience is. This is done using a literature study. The first part of this literature study focussed on general and field-specific definitions of resilience. This resulted in the definition of resilience of river systems as used in this study: the resilience of a river system is the ability of the system to continue functioning during a disturbance. Where continuation of functioning is defined as the continued achievement of the goal of a certain function, such as the continued production of crops for the function of agriculture, even if this only occurs to a smaller extent, and the continued shipping of goods for the function of shipping. The disturbances considered are short-term disturbances, such as droughts and pollution plumes. After the determination of the definition of resilience of river systems several remaining questions need to be answered. The impact of disturbances on the different river system functions has to be determined and visualised. Next, the impact of these disturbances has to be classified. Finally, the resilience of river systems should be assessed using the classification for the impact of these disturbances. The second part of the literature study, focussing on the assessment of resilience, is used to help determine, visualise and classify the impact of disturbances. The development of the final method is an iterative process between application to a case study and the amendment of the method based on this application. Using the results of the literature study, a first…

▼ Wood can be used to rehabilitate degraded water bodies (lakes and
rivers). However wood has historically been removed from river systems to improve flood protection, inland navigation and drink water quality. These actions reduced and degraded the aquatic habitat of the effected river systems. Rijkswaterstaat is interested in reintroducing wood to rehabilitate the aquatic (and terrestrial) habitat of river systems. In order to successfully reintroduce wood in river systems it is necessary to identify where the wood comes from? How is it transported? How does it accumulate? And what are the effects on stream ecology and geomorphology? This knowledge can be used to determine if already naturally occurring wood in river systems can be managed to achieve the goal of river rehabilitation. If no or too little wood is present in the river system, an engineered solution can be used. This engineered solution is known as Engineered Log Jam (ELJ). These structures use wood as construction material to rehabilitate
rivers. The stability, design and implementation of ELJs in
rivers is a complex process. This report provides an overview on the identification, classification, importance and management of wood in river systems. Secondly the gives an overview of studies done on the stability of wood in
rivers, the design (process) of ELJs and the geomorphological impact of ELJs on river systems. From the studies reviewed in this report it is clear that wood plays an important role in river systems. Wood directly effect river ecology and geomorphology by forming log jams. Proper management of wood is therefore required if one wishes to retain a healthy river system. Where one wishes to (re)introduce wood in a river system using ELJ structures the design process is vital. The first step is to identify the characteristics and properties of the river section. The second step is designing the correct ELJs for the desired goals. The last step is constructing and monitoring the ELJs. Evaluation is important to obtain points of improvement.

▼ Deep, narrow corridors of concentrated water vapor transport referred to as “atmospheric
rivers” (ARs) are an important contributor to extreme precipitation in the western United States. This study takes a closer look at the climatology of AR events that generate precipitation on the eastern slopes of the Sierra Nevada, with a particular focus on the Tahoe region. Daily measurements of winter precipitation recorded at 7 cooperative weather stations in and around the Tahoe basin are examined for the period from WY1974–2012 and the Climate Prediction Center/National Centers for Environmental Prediction gridded daily precipitation analysis is used to extend these results along the length of the Sierra crest from WY1949–2012. An inventory of AR landfall dates is generated using the National Centers for Environmental Prediction-National Center for Atmospheric Research model reanalysis and rawinsonde data from Oakland (OAK) are used to look at upper atmospheric conditions, including the presence of vapor transport by low- and mid-level jets on storm days. Strong mid-level vapor transport needs to occur in tandem with low-level transport in order to achieve the most extreme two-day precipitation in the Tahoe basin. Furthermore, when low- to mid-level vapor transport was present on AR days, the magnification of two-day precipitation intensity decreased with distance from the Sierra Crest; on non-AR days the relative increase in two-day precipitation intensity due to low- and mid-level vapor transport did not vary based on distance from the Sierra Crest.

▼ A major difficulty encountered by river engineers is the unavailability of a reliable relationship between the flow discharge and the sediment transport rate. Most of the published transport rate prediction methods have been developed using measurements of uniformly sized sediment. It has been found that non-uniformly sized sediment exhibits very different behaviour from that of single sized sediment. If no sediment is introduced into a reach then as the bed degrades coarse material progressively accumulates on the surface, significantly reducing the transport rate. This can be effectively reduced to zero, the bed is then said to be armoured. Four experiments were conducted, in which there was no feed or recirculation of sediment and the flow rate was held constant. These experiments indicated a two phase development during the formation of an armour layer. The initial phase was dominated by the rapid coarsening of the bed surface with a large drop in the sediment transport rate, followed by a second longer phase characterised by the re-arrangement of the surface into a stable grain layout. Numerical simulations were carried out using a mixing layer model. Comparison of the simulated and observed development of transport rate bedload and bed surface composition with time indicated that processes other than grain size sorting were important. Two further experiments were carried out in which the re-arrangement of the bed surface and the adjustment of the near bed flow environment was investigated. This work presents experimental evidence that mixed grain size transport is controlled by a series of inter-related physical processes. All the important parameters such as bed surface composition and grain arrangement, the near bed flow field and the amount and composition of the bedload need to be considered if a mixed grain transport system is to be simulated successfully.

▼ As meandering
rivers laterally migrate over time, they build channel belts. The accumulation of all previous flow paths creates the channel belt. To better understand these ancient
rivers, modern river systems are being mapped to find statistical relationships between current flow path and the channel belt of river systems. It is important to examine a wide range of systems in terms of age, size, and location. The
rivers are being mapped using an ImageJ, interpretations from Saucier (1994) and Google Earth. Three channel belt morphologies are mapped for 15 modern channel belts; the width of the river in relation to the width of the channel belt; the curvature of the meander scars on the channel belt; and the spacing length between unconformable points. Unconformable points are locations where these previous flow paths overlap one another on the channel belt edge. Statistical analysis of the data reveals that the median range for the ratio of channel belt width to mean channel width (W*) is 8.9 to 76, W* for the data set also as a P90/P10 range of 1.6 to 3.7. The median range for the normalized radius of curvature of the channel belt (P*) for the entire data set is 3.8 to 35 and has a P90/P10 range of 16 to 49. The median range for the normalized spacing between unconformable points (L*) for all river reaches in the data set is 2.7 to 24, with a P90/P10 range of 2.9 to 7.6. These variation constraints provide information about the formation of fluvial channel belts and the petroleum reservoirs they can create.

▼ This thesis aims to improve the reliability of the determination of flow resistance in environmentally acceptable channels and floodplains. Special emphasis was placed on addressing the hydraulic effects of vegetation. For this reason, laboratory flume studies with living vegetation were employed. The most notable finding was that, when compared to leafless conditions, the presence of leaves increased the friction factor up to seven-fold. This was strongly dependent on the flow velocity. In addition, the linkage between flow resistance, channel properties, and physical habitat was investigated. For this purpose, field studies were conducted in degraded, restored, and natural channel reaches. To determine friction factor f or Manning's n for non-submerged woody vegetation, a new procedure based on the measurable characteristics of vegetation and flow was developed. A major advantage of this procedure over the old methods was its ability to estimate the flow resistance of woody vegetation in both leafless and leafy conditions. In determining the velocity profile and flow resistance caused by submerged flexible vegetation, the approach developed by Stephan (2002) was found to be suitable. However, a new formulation was proposed for the shear velocity based on deflected plant height. This modification offered better practical applicability than the original formulation, which requires complicated turbulence measurements. In the field studies, the experimental results for friction factors were, excluding those for low flows, in agreement with the values presented in the literature. Overall, the gathered field data from degraded, restored, and natural channel reaches formed a reference data set, which could be useful in other similar restoration or engineering projects. The field studies showed that both flow resistance and cross-sectional geometry were vital factors in determining local hydraulic conditions. The parameters defining these two factors were found to be simple but nonetheless valuable in evaluating the success of a project which aims to restore local hydraulics. A new procedure for applying the success criteria in the post-project evaluation of local hydraulics was developed.
