▼ Large river ecosystems can support a complex network of tributaries that provide optimal habitat for fish reproduction. Anthropogenic alteration of rivers and tributaries has been shown to have adverse effects on river fish communities, but few studies have focused on the effects river regulation may have on the reproduction of native suckers (Family Catostomidae). In this study, I evaluated differences in biotic and abiotic factors associated with catostomid reproduction between tributaries of an altered and free-flowing river. I conducted ichthyoplankton sampling using drift nets and larval push nets in tributaries of the Illinois River, which is regulated for navigation, and the lower Wabash River, which is free-flowing and not used for navigation. I sampled three tributaries of the Illinois River (Mackinaw River, Sangamon River, and Spoon River) and three tributaries of the Wabash River (Little Wabash River, Embarras River, and Vermilion River). I collected catostomid larvae from each system twice each month from April until September during 2016 – 2018. I analyzed total relative abundance, catch per unit effort (CPUE), and trends in abiotic variables such as discharge, water temperature, gauge height, dissolved oxygen, pH, and conductivity between the two systems. I also created multiple logistic regression models to determine which variables increased probability of sampling catostomid larvae. For all sample years, the Wabash River tributaries contributed more catostomid larvae than the Illinois River tributaries. My results indicate that the Wabash River system is more influenced by gauge height and water temperature whereas the Illinois River system is more influenced by dissolved oxygen and discharge. Within each system, the tributary that had the highest discharge levels also consistently had the highest number of catostomid larvae. Multivariate analysis of variance also revealed that there was a significant interaction between tributary and all abiotic variables. With a few exceptions, I found that mean CPUE of larval catostomids was greater with larval push nets than drift nets. Drift nets were still an effective gear for sampling and should be continued to be used to collect larvae, especially in shallow habitats that preclude the use of larval push nets. The multiple logistic regression models showed that increasing discharge and water temperature increased probability of larvae capture for the Illinois River tributaries. The model for the Wabash River tributaries had all variables except discharge as significant variables for increasing probability of larvae capture. Overall, my results indicate that there are differences in water quality and catostomid reproduction between the Wabash and Illinois River system. However, specific tributaries contribute the majority of larvae to each system. Assessments of catostomid reproduction should target tributaries in each system with the highest discharge values and use both gear types to effectively sample larval fishes across tributary habitats.

▼ A guiding principle in river science maintains that channel systems evolve to convey the sediment loads and water discharges imposed upon them. Changes in sediment and water inputs may result in adjustments to channel geometry, bed texture, and related parameters. Over the last century, geomorphic processes along the Middle Rio Grande and one of its major tributaries, the Rio Chama, NM, have been altered by intensified land and water management and climate change. Using a GIS, channel characteristics were digitized from georeferenced photographs and analyzed, with particular attention to quantifying measurement error. Along the Rio Grande, average channel widths decreased from 516±67m to 176±7m between 1918 and 1963, mostly due to decreasing peak flows and the implementation of flood control and other engineering measures. From 1985 to 2008, widths decreased from 176 ± 23 m to 146 ± 5 m, primarily over periods of low peak flow. The Rio Chama, downstream of El Vado Dam, narrowed from an average width of 58 m to 44 m, with most of the adjustment occurring after dam closure in 1935. vi Along both rivers, evidence suggested that the spatial patterns of planform change were partly controlled by tributaries confluences. To examine tributary controls along the Rio Chama, elevation and bed sediment data were collected at 200 cross sections situated up and downstream of 26 tributary confluences along a 17 km reach situated just upstream of Abiquiu Reservoir. Compared to reaches between junctions, confluences reduced gradients and bed sediment size upstream of confluences and increased them downstream. These shifts in gradient and bed texture appear to drive variations in sediment entrainment and transport capacity and the relative storage of sand along the channel bed, as well. Although the larger clasts downstream of junctions are harder to move and slow transport, the steeper slopes at these location likely help pass smaller gravel and sands delivered by the tributaries. However, channel form and process are highly variable along the study reach, reflecting variations in the sediment inputs related to watershed geology, mainstem morphology, and past depositional events.

▼ ABSTRACT TEMPERATURE AND RELATIVE HUMIDITY GRADIENTS OF INTERMITTENT AND PERENNIAL TRIBUTARIES IN NORTHERN CALIFORNIA by Eric Hillman Tharsing Willard Master of Science in Geosciences Hydrology/Hydrogeology Option California State University, Chico Summer 2009 Perennial and intermittent tributary streams are extensive components of the stream networks across landscapes. Riparian zones surrounding streams are important components of the bio-scape. Four tributary streams (Two perennial and Two intermittent) were sampled, in the Southern Cascade region of California using methods developed to infer effects of harvesting on microclimatic gradients from stream to upland. These methods were modified to observe the effects of flow on temperature and relative humidity gradients. The objectives of this study are: (1) to characterize flow of perennial and intermittent tributary streams of Big Chico Creek using temperature and stage methods; (2) identify differences in temperature and relative humidity at intermittent ix and perennial sites during different flow conditions; (3) describe effects of perennial and intermittent stream classes on temperature and relative humidity gradients and (4) compare changes in gradients from stream to upland between stream classes. Five temperature and relative humidity loggers were installed along transects running from stream to upland positions at each stream. Linear regressions of relative changes along transects were used to quantify gradients. One and two-way ANOVA were used to determine statistical differences in gradients and relative changes along transects respectively. This was done between stream classes, transects, and transects and Stations for appropriate time periods. Results point to distinct temperature and relative humidity gradients for perennial and intermittent streams (0.0195 and 0.0102 C/m), during daytime dry conditions, while the intermittent stream is dry and the perennial is still flowing. For the same time period significant differences exist between stream Stations and all other Stations (7.5m to 45m) along the perennial transect, while intermittent statistical differences don???t exist until near upland Stations (30m to 60m). The study indicates that perennial and intermittent streams have distinctive temperature and relative humidity conditions above the stream during the peak daytime, when the intermittent ceases to flow and the perennial continues to flow. Additional site specific data are needed for various site conditions in order to determine if generalizations can be made about these stream classes.

▼ In recent years, reports of nuisance algae have increased within the Great Lakes Basin. These nuisance algal blooms have been known to include potentially hazardous cyanobacteria. There is a concern that harmful algal blooms are occurring more frequently which could have adverse impacts to wildlife, human activities and public health. However, there is a general lack of information on the distribution, frequency and taxonomic composition of algal blooms within the Great Lakes basin, particularly in eastern Ontario. This thesis addresses this lack of information through intensive sampling by researchers and citizen scientist volunteers. The St. Lawrence River/Lake St. Francis tributaries were used as a model system to evaluate the effects of various stressors (environmental, landscape and water quality) on algal density and frequency of harmful algal blooms. The monitoring program, run in both 2013 and 2014, found that algal assemblages were dominated by diatoms, followed by chlorophytes, and on average only ~ 1% of overall algal composition were cyanobacteria, with even smaller amounts of chrysophytes, euglenophytes, dinophytes, and cryptophytes. Multiple linear regression models were developed to predict both overall algal density and cyanobacteria density from physical and chemical variables; water temperature, total phosphorus and day of year emerged as the best predictors of algal density, and water temperature and depth were the best predictors for cyanobacteria. However, the variance explained by these models, although significant, was low. The between-year variance in algal density and composition was high, likely related to differences in precipitation. The reliability and utility of citizen science for the monitoring of harmful and nuisance algae occurrences was also evaluated. Results suggest that citizen science monitoring programs provide data complementary to traditional monitoring, although challenges associated with volunteer recruitment and retention can affect the overall effectiveness of this approach. Significant dissimilarities in community composition were observed between volunteer and researcher-collected samples, with volunteers collecting more chain forming diatoms and rare taxa. Citizen scientist samples also exhibited higher algal density than researcher-collected samples related to either differences site choice and/or the method of sample collection.

▼ Stonecats (Noturus flavus, Rafinesque 1818) are designated as a Vermont state-listed endangered species because their known distribution is limited to two systems, the LaPlatte and Missisquoi rivers. The restricted distribution and lack of knowledge on abundance in either river is cause for concern in the continued survival of these populations. Based on the capture numbers and large size range of individuals, we predicted that the population in the LaPlatte River, which provides quality benthic habitat, is stable. However, the Missisquoi River population has the potential for increased intermittent mortalities from two sources, lampricide (3-trifluoromethyl-4-nitrophenol) treatment every four years and dewatering during drought conditions. In 2012, 2013, and 2014 we captured, PIT tagged (> 90 mm total length), and VIE marked all Stonecats collected using backpack electrofishing and minnow traps in the LaPlatte and Missisquoi rivers. A total of 1252 were PIT tagged in the LaPlatte River and 125 in the Missisquoi River. First we estimated survival and seniority of Stonecats in the LaPlatte River, using the Pradel model in Program Mark, and derived an average annual lambda of 0.9826. The population estimates from the LaPlatte River were modeled in a population viability analysis (PVA). Few Stonecats were captured in the Missisquoi River, so we used the PVA model to estimate the extinction rates with increased intermittent mortalities on 4-, 6-, and 8-year cycles to predict the long-term viability of the population. With an initial number of 2000 individuals, the population became extinct 100% of the time with an increase in mortality of 0.1 on a 4-year cycle. Our results indicate that the LaPlatte River population is stable, but the Missisquoi River population, in the area affected by lampricide, is not. These results are informative for developing future management scenarios, however, our approach has uncertainty that can only be addressed through obtaining more data on the Missisquoi River population.

▼ The Vermilion River and major tributaries (VRMT) receive numerous inputs from point and non-point sources along their continuum. In addition to these inputs from the surrounding landscape, a hydroelectric impoundment and control dams/weirs have modified the natural flow regime. Further development in the Vermilion watershed has been proposed and there are concerns that it will push the system beyond a tipping point, leading to a state of permanent impairment. In order to understand how ecosystem health may be impacted by future stressors baseline water quality and phytoplankton data were collected monthly (6 months per year) over a period of two years (2013-2014) for twenty-eight sites. Landscape-scale data were also extracted for these sites using the geographical information software QGIS. A broad range of quaternary geology types, land-cover types, and road densities were found to exist in the VRMT study area. Impervious land-cover types (i.e. barren and developed land-cover) and road density were positively correlated with many water quality parameters, whereas, forest land-cover was negatively correlated with many water quality parameters. Principal component analyses revealed that sites on the main-stem of the Junction tributary exhibited above average values for the majority of water quality parameters. Notably, sites located downstream of the Sudbury WWTP had above average values for chlorophyll-a, total phosphorus, nitrate, and nitrite, whereas the site upstream had above average values pH and total kjeldahl nitrogen. Further correspondence analyses and canonical correspondence analyses demonstrated that the abundance and composition of major phytoplankton groups and genera were different between sites and likely influenced by the surrounding landscape (i.e. point and non-point sources) and water quality differences. For all CCAs general biological/chemical parameters and nutrients were slightly better predictors at explaining the variation in phytoplankton biomass compared to metals. Of these general biological/chemical parameters and nutrients, many of parameters were important or moderately important (e.g. Chl-a, CaCO3, DOC, Cond, Cl, TP, TN, TKN, NO3, and NO2). The major phytoplankton group Chlorophyta (i.e. green algae) was abundant at many sites located in Junction tributary in 2013 and in 2014, however, CC-12 which was also located in the Junction tributary was primarily dominated by the major phytoplankton group Bacillariophyta (i.e. diatoms) and had extremely low biomass for all sampling dates. In addition, the major phytoplankton group Cyanophyta (i.e. blue-green algae) was regularly abundant later in the sampling season at ELA-25 for both years and this major phytoplankton group was mainly comprised of Microcystis.

▼ Algal blooms occur seasonally in the Chesapeake Bay and its tributaries, and while the consequences of algal blooms have been qualitatively and quantitatively assessed, the causes of algal blooms and mechanisms of bloom initiation are still not well understood despite decades of research. In order to understand nutrient dynamics and other factors that promote the initiation of algal blooms, the Lafayette River, a tidal sub-estuary of Chesapeake Bay that experiences seasonal algal blooms, was sampled daily in the fall of 2005. Three phytoplankton blooms (Chlorophyll a concentrations exceeding twice the average of monthly measurements from 2000-2009) occurred during this period, a mixed bloom of Akashiwo sanguinea and Gymnodinium sp., a Skeletonema costatum bloom, and a monospecific Gymnodinium sp. bloom. Over the sampling period, nutrient concentrations increased following precipitation events and were elevated between bloom periods but low during blooms. All measured forms of nitrogen were positively lag-correlated with dinoflagellate abundance between 3 and 5 days in reverse time. Concentrations of NO2- reached 10 μM between September and October, indicative of incomplete nitrification. Over a 24-h period, nutrient concentrations and chlorophyll a biomass varied by an order of magnitude and were strongly linked to the tidal phase. Massive blooms of the harmful alga Cochlodinium polykrikoides Margalef occurred in the lower Chesapeake Bay and its tributaries during the summers of 2007, 2008, and 2009. The Lafayette River appears to act as initiation grounds for these blooms. However in 2008 there were also localized sites of initiation and growth of C. polykrikoides populations within the mesohaline portion of the James River. In 2008, bloom initiation appeared to be correlated with intense, highly localized rainfall events during neap tides. During 2009, bloom formation occurred when water temperatures had stabilized at 26°C during a period of calm winds, neap tides, high positive tidal residuals, higher salinity, low nutrient concentrations and a low dissolved inorganic nitrogen (DIN) to dissolved inorganic phosphorous (DIP) ratio (DIN:DIP). Tidal flushing transported the C. polykrikoides bloom from the Lafayette River into the lower James River where it was transported upriver by local estuarine circulation. A combination of physical factors including, seasonal rainfall patterns, increased stratification, nutrient loading, spring-neap tidal modulation, and complex estuarine mixing and circulation allowed C. polykrikoides to spread and form massive blooms over large portions of the tidal James River and lower Chesapeake Bay. The primary control on the formation of algal blooms in the Lafayette River was water column stability, and bloom formation occurred during neap tides, when there was low wind-driven mixing, and increased buoyancy from rainfall and runoff.

▼ Human and environmental health continues to be threatened by persistent organic pollutants in the Great Lakes ecosystem. Polycholorinated biphenyls (PCBs) are considered one of the most toxic contaminants in the Great Lakes due to their recalcitrance, bioaccumulation, lipid solubility, and adverse health effects. The three main questions examined in this research were: 1) Do PCB concentrations vary between largemouth bass (Micropterus salmoides), northern pike (Esox Lucius), smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus) in west Michigan tributaries of Lake Michigan; 2) Do PCB concentrations vary on a watershed level among Manistee Lake, Muskegon Lake, Pentwater Lake, Tippy Pond, and White Lake; and 3) What are the risk levels associated with fish consumption by members of Little River Band of Ottawa Indians (LRBOI) and sport fishermen for the watersheds and fish species examined? Fish samples from Manistee Lake and Tippy Pond were caught via hook and line by members of LRBOI during 2004-2006 and 2008-2009. Fish samples from Muskegon, Pentwater, and White lakes were taken via boat electrofishing by the Michigan Department of Environmental Quality and the Annis Water Resources Institute during 2003-2006 and 2008-2009. The basins were chosen for their extensive use for recreational and tribal fishing. Fish were fileted, homogenized in a grinder and lipids from 20-g samples were extracted. Negative chemical ionization gas chromatography/mass spectrometry, gas chromatography with an electronic capture detector, and gas chromatography/high resolution mass spectrometry were used to measure PCB congener concentrations the fish tissue samples. Because of the variable methods in PCB congener measurements, PCB congeners were cross referenced and only the congeners that were found across all three methods were used in the statistical portions of the study. For the exposure and risk assessments, only those congeners that were measured and found in Aroclor 1254 were used for total PCB exposure calculations. The results showed that walleye were significantly higher in PCB content than largemouth bass, northern pike and smallmouth bass (p < 0.05). Walleye were significantly higher in lipid content (p < 0.05), which was linked to the high PCB content. Fish from Manistee Lake were significantly higher than Muskegon Lake, Pentwater Lake, Tippy Pond, and White Lake (p < 0.05). In addition, exposures of sport anglers exceeded the reference dose of Aroclor 1254 in Manistee Lake with walleye from Manistee and White Lakes more than 10x the reference dose. Exposures of tribal members (LRBOI) exceeded 10x the reference dose in all species from Manistee Lake and walleye from Muskegon and White Lake. The risk assessment results suggest that basin specific consumption advisories should be considered for high risk groups.

A regiÃo do baixo rio Araguaia sofre a influÃncia de um pulso de inundaÃÃo que causa modificaÃÃes no ambiente. O presente trabalho teve por objetivo identificar os efeitos espaciais (calha e tributÃrios) na estrutura da assembleia da ictiofauna. As amostras foram realizadas bimestralmente entre marÃo e setembro de 2009, em 14 locais (7 no rio Araguaia e 7 em tributÃrios), os peixes foram coletados com redes de espera expostas por 24 horas, sendo que para as anÃlises, o esforÃo foi padronizado e indexado em captura por unidade de esforÃo em nÃmero e biomassa, em seguida os atributos da assembleia e abundÃncia total foram calculados e posteriormente os padrÃes de distribuiÃÃo espacial foram identificados atravÃs de anÃlises bifatoriais. A diversidade beta foi estimada como a taxa de renovaÃÃo de espÃcies. Uma anÃlise de ordenaÃÃo indicou a formaÃÃo de 3 eixos e seus escores foram retidos para anÃlise de PerManova. A anÃlise de espÃcies indicadoras foi realizada para determinar se existiam espÃcies indicadoras de locais. A riqueza de espÃcies e abundÃncia de peixes foram maiores na calha do rio Araguaia durante a estaÃÃo seca. A diversidade na calha do rio Araguaia nas estaÃÃes vazante e seca divergiu dos tributÃrios nas estaÃÃes enchente e cheia em relaÃÃo Ã abundÃncia em nÃmero de indivÃduos e a diversidade beta mostrou que o rio Araguaia e os tributÃrios apresentam suas assembleias de forma nÃo aleatÃrias. A equitabilidade nÃo apresentou diferenÃas significativas entre os locais e as estaÃÃes. A avaliaÃÃo de espÃcies indicadoras permitiu identificar algumas espÃcies que sobressaem em relaÃÃo Ãs outras, principalmente na calha principal na estaÃÃo seca, tais fatos podem estar relacionados Ãs mudanÃas no ambiente entre as estaÃÃes, alagando as margens e vÃrias estruturas ao longo do rio, disponibilizando novos habitats e fazendo que algumas espÃcies procurem ambientes mais propÃcios as suas necessidades durante as diferentes estaÃÃes do ano.

The region of the lower Araguaia River is influenced by a flood pulse that causes changes in the environment. This study aimed to identify the spatial effects (main river and tributaries) on the assembly structure of fish. Samples were taken every two months between March and September 2009, at 14 sites (7 in the Araguaia River and 7 in tributaries), fishes were collected with gill nets exposed for 24 hours, for the analysis effort was standardized and indexed in catch per unit of effort in number and biomass, then the attributes of the assembly and the total abundance were set and spatial distribution patterns were identified through factorial analysis. The beta diversity was estimated as the rate of renewal of species. An ordination analysis indicated the formation of three axes and their scores were retained for a PerManova analysis. Analysis of the indicator species was performed to determine if there were local indicator species. Species richness and abundance of fish were higher in the channel of the Araguaia River during the dry season. The diversity in the channel of the…

▼ Light-framed wood residential buildings continue to suffer damage from extreme wind events, even at wind speeds below design levels. One of the major findings in post-hurricane damage investigations is that a continuous load path to transfer the wind uplifts loads acting on the roof into the foundations was missing. The roof-to-wall connections are major components in this load path that have inadequate capacity during extreme wind events causing catastrophic failure. The objective of this dissertation is the evaluation of the vertical structural load paths due to wind loading on the roof of a low-rise, light-framed wood building. Through the use of static influence coefficients developed on a 1/3rd-scale wood building instrumented at twenty (20) roof-to-wall and wall-to-foundation connections, the vertical structural load paths were determined. Using a database-assisted design (DAD) methodology combining the structural influence coefficients with wind tunnel-derived pressure coefficients, estimated peak structural connection loads were determined. These peak loads were compared with loads estimated from two other previously established methods, namely the covariance integration (CI) and load-response-correlation (LRC) methods. Generally, the CI and LRC methods estimated the mean connection loads well but underestimated the peak loads. The hypothesis of the research is that a wood-framed roof is sufficiently flexible to be excited by dynamic wind loads. An analytical finite element model of a 21-truss roof was developed to investigate the effects of dynamic loads on the roof. A fundamental frequency analysis was performed on the roof and various roof components to determine the first vertical mode of vibration. The analysis showed that the roof is sufficiently stiff with fundamental frequencies well above the low frequencies that dominate natural wind flows. This finding discredits the hypothesis and shows that the static influence coefficients are valid for light-frame wood structures. The DAD-derived peak reactions were also compared with design loads determined using the ASCE 7-05 wind load provisions and the prescriptive loads provided by the Wood Frame Construction Manual (WFCM). The roof-to-wall connection design loads determined using the ASCE 7-05 main wind force resisting system (MWFRS) procedures (both the low-rise and all heights provisions) underestimate significantly the peak loads developed using the DAD methodology. However, the design loads determined using the ASCE 7-05 components and cladding (C & C) provisions provide a better estimation of the peak loads, but still underestimate the DAD-derived peak loads at some roof-to-wall connections. This significant and unanticipated finding is due to the fact that the influence coefficients used to develop the MWFRS were for steel portal frames, which are not applicable to light-frame wood construction.

▼ Landscapes posses many scales of variability, from hillslopes to the river network structure, and have been the subject of intense research over the past three decades. Despite this tremendous variability, it has been well documented by now that scale-invariances do exist in several landscape attributes reflecting the natural organization of processes responsible for the formation of those landscapes. The availability of very high resolution (sub-meter scale) digital topography data from laser altimetry (LiDAR) offers an unprecedented opportunity to probe into the structure of landscapes at scales never imagined before and extract properties useful for modeling water, sediment, and nutrient fluxes in a watershed. In this work, we take advantage of these high resolution topography data to introduce new metrics for quantifying landscape organization and explore scaling laws across the continuum of hillslope-fluvial regimes. The innovations we introduce rely on: (1) adapting a new scale parameter which we call ``directed distance from the divide'' which allows examining divergent and convergent parts of the landscape under a single framework; (2) using this new scale parameter to identify the signature of landslides on a landscape allowing thus an objective mapping of those landslides; (3) introduction of the ``incremental drainage area'' function along the mainstream to quantify the hierarchy and clustering of tributaries; and (4) introduction of an non-traditional horizontal function that measures ``valley width''as one fills up the channels beyond their banks and maps the left and right extend of the landscape. A common theme in all of the above developments is the quest for mapping the complex three dimensional structure of landscapes onto simpler, preferably one dimensional, functions that reflect different aspects of the landscape organization. Once this is accomplished, our common method of analysis relies on the theory of multi-scaling using wavelets, i.e., in quantifying how the statistical structure of the extracted attributes changes when one sees them at different scales.

▼ Anthropogenic climate change poses an imminent threat to limited freshwater resources in the southwest United States as surface temperatures are expected to rise and precipitation events become less predictable. This in turn will increase the reliance on local freshwater resources, and, if managed carelessly, may threaten sensitive aquatic and riparian ecosystems where groundwaters emanate at springs that supply perennial tributaries. Understanding the influences on perennial tributary water chemistry is critical to appropriate management of freshwater resources and riparian ecosystems that sustain native species. Geochemical signatures from water-rock interaction provide a means to determine primary influences on variability of water chemistry in groundwater and surface waters. To characterize the water chemistry variability in perennial tributaries of the Colorado River in the Grand Canyon region, hydrochemical data, geochemical models, and S isotopes provide substantial evidence for water-rock interactions being the primary influence on water chemistry. A hierarchical cluster analysis grouped perennial tributaries based on major ion chemistry, yet other characteristics not included as variables, such as TDS, geospatial extent, and sulfur isotopes (del34S) generally follow trends defined by the clustering. Piper plots coupled with geochemical models supports the hypothesis of water rock interactions controlling water chemistry variability. The twenty sampled waters range in composition from Ca/Mg-HCO3, to Ca-SO4, to Na-Cl type waters suggesting varying degrees of influence from carbonate (dolomite and limestone) and marine evaporite (gypsum and halite) dissolution on water chemistry. Geochemical models were created to characterize evolution of groundwater through carbonate aquifers with or without evaporites present, which matches observed chemical composition variability. Sulfur isotopes also support a model of variability in water chemistry induced by water-rock interaction without the need for an additional source of sulfur from mantle derived fluids (H2S(gas)) as has been hypothesized in previous studies in this region. Results from sulfur isotopes determined 7 of the twenty perennial tributaries analyzed for del34S have dissolved sulfate derived from overlying marine evaporite rocks of Permian age. These tributaries generally represent high TDS waters (550 to 1,600 mg/L and one tributary with 200 mg/L) indicating water-rock interaction with marine evaporites is the primary influence on TDS. Three tributaries are only influenced by the dissolution of carbonates, while two tributaries are influenced by likely sulfide mineral oxidation, though influence of H2S deep magmatic/mantle gases that also source CO2 to the waters has been proposed in previous studies and cannot be ruled out without additional chemical and isotopic analysis of gases in spring waters. Two groups from the cluster analysis represent seven tributaries that fall between del34S +6 to +8 per mille and are relatively low TDS waters (200 to 500… Advisors/Committee Members: Navarre-Sitchler, Alexis K.

▼ En Guinée, la disponibilité des ressources en eau est soumise à de graves problèmes de gestion avec des conséquences importantes pour les populations, notamment à Kankan où la plupart des puits tarissent pendant la saison sèche, et où la fourniture régulière de l’eau à partir de la rivière Milo n'est pas assurée dans tous les quartiers de la ville. Le Milo et son bassin versant représente donc un enjeu important pour les habitants de cette ville. Le Milo (480 km de long) qui draine un bassin versant 13 810 km2 est le plus important des affluents rive droite du Niger. Pour évaluer l’impact du bassin versant du Milo et de la ville de Kankan sur la qualité des eaux et des sédiments de ce cours d’eau, 30 échantillons de sédiments de fond ont été prélevés au cours d’une première campagne (juin-juillet 2013) sur l’ensemble des cours d’eau du bassin versant, tandis que durant une deuxième campagne (avril 2014-mai 2015), un suivi régulier a été mis en place sur le Milo en amont et en aval de Kankan. Au cours de cette dernière, 232 échantillons d’eau du Milo (dont 116 utilisés pour l’isotopie), et 26 échantillons de sédiments de fond ont été prélevés sur les stations de Bordo (amont de Kankan) et de Karifamoriah (aval de Kankan). Les concentrations en éléments majeurs et traces, terres rares, COP, COD, pH, alcalinité, l’azote organique, les isotopes de l’oxygène et de l’hydrogène, ainsi que la micro-granulométrie des sédiments ont été mesurés. Les résultats obtenus durant le cycle hydrologique 2014-2015 ont permis d’estimer le flux de matières exportées en solution par le Milo à Kankan à 47 863 t.an-1 et le flux de matières particulaires à 76 759 t.an-1. 92% de ce tonnage est exporté durant la période des hautes eaux. Ces flux permettent d’estimer des vitesses moyennes d’érosion physique (8 t.km-2.an-1) et d’altération chimique (5 t.km-2.an-1) du bassin relativement faibles. Le flux spécifique de CO2 consommé par l’altération chimique est lui aussi relativement faible (76.103 mole.km-2.an-1), mais il reste dans la moyenne des flux de CO2 mesurés sur les bassins couverts de sols latéritiques. Le degré de contamination des sédiments et sa variation spatio-temporelle ont été évalués grâce au calcul du facteur d’enrichissement (FE), en normalisant les concentrations en éléments traces par rapport à Al, Sc et Ti et en prenant le PAAS et l’UCC comme matériaux de référence. La quasi-totalité des éléments traces proviennent essentiellement des processus d’altération et sont d’origine naturelle. Toutefois, un enrichissement modéré à significatif (5 < FE < 20) a été mis en évidence pour Zr et Hf (enrichissements naturels) et As et Sb (impacts anthropiques). Finalement, l’apport anthropique en éléments traces, quand il existe, reste modéré. Les profils de concentrations en terres rares ont permis de montrer que la signature géochimique des sédiments de fond du Milo est homogène sur l’ensemble du bassin et caractéristique des sols latéritiques, non perturbée par la ville de Kankan et elle est proche des signatures du PAAS et de l’UCC.… Advisors/Committee Members: Probst, Jean-Luc (thesis director), Sidibe, Kaba (thesis director).

▼ Regional curves, which relate bankfull discharge and channel geometry (cross-sectional area, width, and mean depth) to drainage area in regions of similar climate, geology, and vegetation, have greatly aided in creating target natural channel designs for stream restoration efforts. Regional curves were developed for peninsular Florida based on cross-sectional and longitudinal survey data collected at 17 gaged and 28 ungaged as near-to-natural streams, ranging in drainage area from 0.2 to 311 square miles and valley slope from 0.02 to 2.27%. Based on an analysis of prevalence among sites, slopes, and hydrologic data, the elevation of the flat floodplain was determined to be the most reliable bankfull indicator at sites with a wetland floodplain, while the elevation of the inflection on the bank was the most reliable indicator at sites with an upland floodplain. Analysis of bankfull indicator slopes further revealed that a water slope threshold of approximately 0.5% exists, above which bankfull indicators appear to more reliable, suggesting that slope-area techniques for calculating the bankfull discharge may be unreliable in peninsular Florida streams with a water slope less than 0.5%. The dataset was further divided based on physiography (flatwoods versus highlands), geography (northern versus southern peninsula), and floodplain types (wetland versus upland and cypress-dominated versus non-cypress-dominated) to determine if significant differences exist in the bankfull regressions and/or various dimensionless ratios (sinuosity, width-to-depth, maximum depth-to-mean depth, valley slope, and maximum discharge-to-mean annual discharge) among various peninsular Florida stream subsets. Streams with wetland floodplains were found to have a significantly greater bankfull area and bankfull width than streams with an upland floodplain. Also, streams with cypress-dominated floodplains had a greater width-to-depth ratio than streams with non-cypress-dominated floodplains. Further, streams draining flatwoods physiographies were found to be flashier. These differences may be important considerations when designing natural channels in peninsular Florida. Annual peak flow data for the gaged sites were analyzed to estimate the bankfull discharge return interval using Log Pearson Type III distributions. The bankfull discharge ranged from less than one year to 1.44 years, which is more frequent than the average 1.5-year return interval often cited in the literature. Based on analysis of the flow duration at gaged sites, bankfull discharge for peninsular Florida streams is equaled or exceeded approximately 21% of the time on average, or about 77 days per year. On average, the bankfull discharge is roughly four times that of the mean annual discharge and is 35% of the 1.5-year discharge. Lastly, the regional curves developed for peninsular Florida were compared to regional curves previously developed for other regions of the southeastern United States Coastal Plain. Peninsular Florida bankfull channels were found to have a lower… Advisors/Committee Members: Wise, William R. (committee chair), Crisman, Thomas L. (committee member).

▼ Dans un contexte de changement climatique, la compréhension du régime thermique des cours d’eau est un enjeu important. En mesurant le rayonnement dans le spectre électromagnétique de l’infrarouge thermique (IRT : 0,4-14µm), la télédétection IRT offre la possibilité d’obtenir une cartographie de la température de surface à différentes échelles spatiales. L’approche multi-échelle est ainsi le fil directeur de ce travail.Dans le premier temps, nous utilisons des images satellites Landsat ETM+ pour caractériser les structures thermiques longitudinales et temporelles d’un grand continuum fluvial : le Rhône français (500 km). Une méthode automatique supprimant les pixels contaminés par les entités exondées, est développée, améliorant ainsi la précision des données. Les images nous permettent de comprendre les effets thermiques des affluents et des centrales nucléaires. L’Isère est la principale source d’eau froide, alors que les centrales nucléaires du Bugey, de Saint-Alban et de Tricastin réchauffent le fleuve. Nous mettons en évidence des anomalies thermiques au niveau des aménagements hydroélectriques. Par rapport aux canaux, les Rhône court-circuités (RCC) sont plus sensibles aux conditions extérieures du fait de leur géométrie et de leurs conditions hydrauliques.Dans un second temps, les travaux se focalisent sur un tronçon plus court (50 km) : l’Ain dans sa basse vallée où quatre campagnes IRT aéroportées sont réalisées. Nous développons une méthode statistique permettant de calculer l’incertitude de mesure associée à la construction des profils longitudinaux de température de l’eau. Les artefacts des vraies tendances longitudinales sont ainsi différenciés. Pour comprendre ces tendances, un modèle 1D (thermo-hydraulique) est mis en place sur 21 kilomètres. Il considère les flux de chaleur à l’interface eau-air et les propriétés géométriques ainsi qu’hydrauliques de la rivière.

Ces arrivées phréatiques peuvent refroidir l’Ain de 0,6°C en été lorsqu’elles représentent 15,7% du débit total.Une échelle plus fine est explorée enfin. Le travail porte cette fois sur neuf tronçons en tresses (1 km) pour lesquels des images IRT à très haute résolution spatiale sont acquises. En caractérisant les distributions spatiales de la température, nous identifions deux types de tronçons. Le premier montre une très faible variabilité thermique spatiale tout au long de la journée. Les cours d’eau de ce type ont bien souvent un régime hydrologique proglaciaire avec des débits estivaux élevés, ce qui tend à homogénéiser la température. Le second type présente une hétérogénéité thermique élevée. La température des chenaux courants varie avec la température de l'air. En revanche, la température des chenaux alimentés par des eaux souterraines est relativement constante au cours de la journée.

▼ In-stream mining of alluvial rivers is a readily available source of construction material. River managers of the years did not consider the ecological and physical effects that removal of alluvial material has caused. Our study examines the impact of in-stream and floodplain mining on the Leaf River, Mississippi and tributaries and determines if a decade after a mining moratorium is a sufficient amount of time to stop degradation. The Leaf River is a large tributary of the Pascagoula River with no in-stream mining but some floodplain mining. The Leaf River has five major tributaries of these three rivers were analyzed. The Bowie River has large in-stream mining pits and adjacent floodplain mining, the Bogue Homo River has no history of in-stream or floodplain mining and Thompson Creek has in-stream and flood plain mining. Lateral migration rates and point bar areas have decreased in the intensively mined rivers suggesting some recovery in the channel system. An increase in vegetative cover on point bars are contributing to a level of stability in the mined reaches. Stream power is a driving force of channel change in streams and rivers. The higher the stream power the more change likely to be found in the system. The Leaf River and two tributaries were analyzed. It was found that sinuosity, point bar area, erosion change indices and average lateral migration rates of the stream channels had a correlation to specific stream power, but not all change characteristic variables were consistent for all rivers. The more disturbed streams showed a correlation to lateral migration and point bar area but not erosion change indices. The planform change response in disturbed river systems is difficult to predict. Channel response and recovery is dependent upon the extent of human disturbance such as mining and resistance factors such as geology and vegetation.

▼ Seasonal flow conditions and catfish larvae production were evaluated in the Madre de Dios River (southeastern Peru) in order to understand the influence of environmental conditions on the reproductive behavior of a group of large catfishes (Siluriformes: Pimelodidae), important species in commercial fisheries, that annually arrive into this headwater region for spawning. A simple stochastic model is presented to describe the influence of the natural flow regime of this river on the downstream transportation of catfish larvae. Temporal and spatial drifting patterns of these catfish larvae were also analyzed and described within the river channel, and the significant ecological role of this region was emphasized in the completeness of life cycle of this important Amazon fish resource. One year of daily river stage records were related to weekly larval catches to determine the association between floods and spawning events, and on the basis of hydro-climatologic characteristics of Andean-Amazon regions, available long-term historical rainfall records were employed to determine the inter-annual variability of floods within the Madre de Dios Basin. Larval catches obtained from five cross sectional transects placed in a 12 km-section of the channel of Madre de Dios River, and surface and deep samples, were employed to assess larvae drifting within the channel. Major larval drift occurred during the high water season, and specifically they appeared to be associated with stages of over the 5 m, a level which served as a physical indicator of the river, triggering spawning responses of these species, termed a ?Biologic Hydrological Significant Event? (BSE). Timing of these BSEs, estimated from the historical rainfall records, described a uniform distribution during the wet season, and their inter-arrival times were exponentially distributed. These observations provided the basis of the stochastic model describing the likelihood of larvae releases from this headwater region to the lowland Amazon. Within the channel, larval drift occurred mostly along the banks of the river, however no significant spatial differences in the numbers of fish larvae moving downstream were found along the sampled sections, which indicated that spawning habitats were located near this Andean foothill region. The permanent flood pulses during the periods of larval peaks and the limited availability of floodplain areas in the channel indicated that larvae do not stay in this region. Analysis of hydrologic regime and catfish larvae drifting in the Madre de Dios Basin demonstrated the strong association between fish fauna and the aquatic environment, the fundamental role of the Amazon headwater regions in fish abundance and diversity, and the function of river channels on catfish spawning and migrations. It is fundamental to maintain and protect hydrologic conditions in the Andean-Amazon region in order to keep aquatic life and connectivity of the complete basin from the headwaters to the estuary.

▼ A digital inorganic water-quality model was developed for Tahoe-Truckee System, Nevada-California. The system consists of mainstem and tributaries of Truckee River between Tahoe City, California and Nixon, Nevada (near Pyramid Lake). Flows and inorganic quality of surface waters are influenced by impoundments behind lakes and dams, diversions for and returns from municipal, industrial, and agricultural uses; and inflow of ground water including from thermal springs. The model is based on the principle of mass-flux-balance and presumes than: 1) inorganic constituents are conservative, 2) complete mixing occurs within each reach, and 3) flows can be recapitulated accurately at the defunct gaging station near Truckee, California. The model was developed from three years of water-quality data collected monthly at approximately 40 sites along the mainstem and on tributaries. Constituents modeled were bicarbonate, chloride, sulfate, sodium, potassium, calcium, magnesium, silica, and total dissolved solids (less silica). The model simulates concentrations of inorganic constituents at selected points on the mainstem and in tributaries near their confluences with the mainstem. Chemical quality of dispersed flows is also simulated. Dispersed components are treated as point sources. Quality of individual inputs is predicted as either concentration or flux. Fluxes and flows are added in a downstream direction and concentrations at points on the mainstem are calculated by dividing flux by flow. In gaged, unregulated streams, concentrations are predicted by a regression equation describing the exponential relationship with flow plus a component to reflect annual-cyclical behavior of differences between regression estimates and observed concentrations. Concentrations in reservoir releases are estimated using multiple regression equations which reflect mixing processes and short circuiting and physical characteristics of the impoundments. Concentrations of dissolved constituents in outflows from Lake Tahoe and Donner Lake have either low amplitude annual-cyclical behavior or are nearly constant with respect to time. Because other data are insufficient for prediction of these concentrations, average monthly concentration or average of all observations is used for estimation as appropriate for time-systematic or constant behavior. Concentrations in dispersed flows in reaches above Farad and in Wadsworth-Nixon reach are estimated from exponential concentration-flow regression equations. Quality of dispersed flow in other reaches is estimated from fourth-order polynomials fit to plots of net flux versus flow. A stochastic component is added to all predictive, equations to account for unexplained variance in estimates. Comparisons between simulated concentrations and data developed in the course of this research showed that simulation was achieved with minimal bias in upper river reaches. Changing patterns in water use in Truckee Meadows resulted in biased estimates in downstream reaches. Comparisons with U.S.G.S. water-quality records… Advisors/Committee Members: Sharp, John V. A.
