▼ An investigation of the sediments and ecology of the dump ground was conducted in March 1995. The primary purpose of the investigation was to analyse factors which may be affecting the benthic biota on the dump ground. These include heavy metal content of the sediments, grain size characteristics of the sediments, and population distribution of the benthic biota on and surrounding the dump ground. It was intended that information obtained could be utilised in future investigations on the ecology of the dump ground, noting changes that have occurred over time. Heavy metal analysis of Cadmium, Chromium, Copper, Mercury, Lead, and Zinc from the dump ground, turning basin, and inner harbour area indicate that concentrations of all heavy metals were all very low and well within resource consent limits. Sediment and ecological samples from 25 sites on and surrounding the dump ground were taken. Two other sites were also surveyed, one from the turning basin, another from the inner harbour area (dredged material). Examination of the sediments has shown that although the dredged material consists solely of mud sized particles the sediments of the dump ground are mainly sand sized sediments. This suggests that during the dumping process dispersion of mud occurs. Mud is transported off the dump ground in a southeasterly direction. Ecological evaluation indicates benthic species diversity and abundance of macrofauna is high, with no species in particular dominating the species assemblage. Comparison between this study and a 1993 survey shows increased diversity over the dump ground. Increased population abundance was evident and larger sized bivalves are indicative of an ageing population. Field experiments examining the kelp beds indicate a decline in the population of Ecklonia radiata from 1993 to 1996. It is thought that this decline may be due to suspended sediment load from the Turanganui River, as the kelp beds are situated in the direction of discharge from the River.

▼ Sediment transport studies incorporating radio frequency identification (RFID) tracers are becoming a key component in understanding sediment transport dynamics due to the data they provide on spatial and temporal variability. This technique involves inserting small glass cylindrical transponders into stones then seeding those stones in the river bed. Existing methods of using RFID tracers involve either manually sweeping the channel bed after a hydrologic event or placing a series of fixed antennas along the channel to detect when sediment containing a RFID tracer passes that point. The first method is limited because it does not correlate the hydrodynamic conditions with the movement of the sediment, while the second method is limited by spatial resolution afforded by the fixed antennas. The goal of this research is to develop a flume with the capacity to accurately measure sediment inputs, transport, and export in real time. This is accomplished by automating the sediment supply, using a sediment trap with a light table to monitor sediment leaving the flume, and implementing an RFID sediment tracking system to provide real time tracking of the movement of individual clasts over the course of an experiment. A tilting flume with sediment supply and capture systems was designed and built with an integrated RFID tracking system to enable sediment transport experiments to be conducted in the flume while continuously tracking the position of RFID tagged sediment. The RFID tracking system, located under the floor of the flume, consists of a carriage containing the antennas, tuners, multiplexing RFID readers, batteries, and rollers to enable the carriage to roll along the flanges of the beam supporting the flume. The carriage is transported back and forth the length of the flume using cogged belts and pulleys powered by a DC motor and controlled by a PLC with limit switches. The identification of RFID tags detected by the carriage is transmitted Bluetooth to a stationary computer that also receives carriage position information from a laser range finder. Validation tests were conducted with vertically oriented RFID tags to establish the detection range and accuracy of estimating RFID tag positions. When no steel cross members were present, an RFID tag could be detected up to 21 cm above the flume floor with streamwise position estimation accurate within 1 cm. When steel cross members or multiple RFID tags were present, the detection range and position estimation accuracy decreased. Further refinement to this technique could be achieve by experimenting with different antenna designs which may provide a larger detection range and by using different type of PIT tags to enable tracking of smaller sized sediment. The developed flume and tracking system will allow us to obtain new and better information about sediment transport which should improve fundamental understanding and aid in the design of channel restoration projects.

▼ The method of using a remotely underwater vehicle (ROV) equipped with push corers to collect marine sediments has fundamental advantages, including precise localization of coring sites, visual recognition assistance from seafloor images, and high-density sampling within a small area. Currently, an ROV that aims to collect marine sediments is always equipped with robotic arms, which are manipulated by a pilot on the surface vessel to carry out sediment sampling through push corers. However, a well-trained pilot is required to assure sampling efficiency. Even to a well-trained pilot, it is still challenging to perform sediment sampling by manipulating robotic arms under bad weather. Moreover, it is essentially infeasible to install robotic arms with high degrees of freedom on small and medium-sized ROVs, causing that sediment sampling is typically excluded from the to-do list of those ROVs. Inspired by the automatic tool changer (ATC) and tool spindle of a computer numerical control (CNC) machine, this research develops a single actuator automatic push corer (APC) that can be integrated with an ROV as a payload device for sediment sampling purposes. The APC has four subsystems, including a vertical sampler, a rotating tube changer, a protective frame, and an electric power and communication medium. The vertical sampler consists of a transmission gear set, a rack, and a clamp. The rotating tube changer consists of a bevel gear pair, a Geneva mechanism, a shaft, and a turntable. The protective frame consists of a motor base and a supporting frame. The electric power and communication medium is a watertight cable that connects the APC actuator to the ROV junction box. Through the combination of the vertical sampler and rotating tube changer, the APC actuator can simultaneously drive these two subsystems to perform the sampling and tube changing sequentially. The APC actuator and components of the vertical sampler and rotating tube changer are all mounted on the motor base. The supporting frame protects the turntable and sampling tubes and allows the APC to firmly settle on the seafloor during sediment sampling. The watertight cable allows the operating voltage and control signals for the APC actuator to be transmitted to the APC from a mother ship through the ROV; it also allows the feedback signals of the APC actuator to be returned back to the mother ship through the ROV.

▼ Centuries-long intensive land use change in the northeastern U.S. provides the opportunity to study the response timescale of geomorphic processes to anthropogenic perturbations. In this region, deforestation and the construction of dams following European settlement drastically altered the landscape, leading to the impoundment of sediment in mill ponds. This legacy sediment continues to be released into transport decades after a dam has been removed or breached. Geochemical tracers can help distinguish sediment sources and understand how sediment moves through a watershed. The South River in western MA is located in a formerly glaciated watershed, and these surficial deposits compose 98% of the area. It experienced two generations of damming, beginning with smaller mill dams in the 18th-19th centuries, followed by the construction of the Conway Electric Dam (CED), a 17 m tall hydroelectric dam in the early 20th century. Legacy sediment deposits from sediment stored behind mill dams cover 1.5% of the watershed area. The CED is located near the outlet of the river, providing a century-long depositional record for the watershed, during reforestation. I hypothesize that sediment mobilized from human activity will contain a different geochemical signature than glacial material, that recent erosion in the watershed is primarily from anthropogenic legacy deposits rather than from glacial age landforms, and channel widening is occurring in reaches of the channel composed of legacy sediment, rather than in glacially confined reaches. These hypotheses were tested through a two part investigation, consisting of a sediment tracing study using Hg, and a Geographic Information Systems (GIS) analysis of channel changes using aerial photographs from 1940 and 2014. Samples were collected from river bank exposures of 11 glacial deposits and four mill pond legacy sites. Two vibracores measuring 476 and 500 cm were collected in reservoir sediment stored behind the CED in 2013 and 2017, respectively. Hg concentrations range from 1-4 ppb in glacial sediment, 3-380 ppb in legacy sediment, and 2-18 ppb and 7-50 ppb in the two CED cores. I used Hg as a tracer to estimate percent contributions to the CED reservoir from each watershed source during the 20th century. Results from a sediment mixing model suggest glacial sources contributed 32 ± 15%, and legacy sediment deposits contributed 68 ± 15% during the 20th century. Based on 137Cs dates on the cores, high amounts of legacy sediment filled in behind the CED prior to 1953 (74 ± 35 %), and background erosion from glacial deposits dominated from 1953 until the reservoir was filled in the 1980s (63 ± 14%). GIS analyses using aerial photographs from 1940 and 2014 indicate that the channel did not significantly widen along any section of the river, however, increases in sinuosity (up to 12%) occurred in the legacy sediment dominated reaches of the channel, and minor increases (1-2%) occurred in the glacial reaches. Overall, these analyses show an increase in the amount of sediment released in… Advisors/Committee Members: Noah P. Snyder (Thesis advisor).

▼ The flux of fine sediment within agricultural watersheds is an important factor determining the environmental quality of streams and rivers. Human activity has significantly altered the hydrological and biogeochemical cycles within terrestrial and aquatic environments through agricultural intensification, tile drainage installation, and urban development. The study of watershed-scale sediment dynamics is of great value for understanding and predicting the response of sediment dynamics to intensive human impact and is crucial to developing management strategies for reducing the vulnerability of the ecosystem to future changes. The primary objective of this dissertation is to investigate sediment sources, sediment transport, and sediment yield in an intensively managed agricultural landscape. This objective was accomplished by combining of field sampling and measurements, laboratory analysis, sediment fingerprinting study, statistical analysis and modeling exploration in the Upper Sangamon River Basin, Illinois. The relative contributions from cropland, grassland, forested floodplain, upper grazed floodplain, and lower grazed floodplain to the suspended sediment in the stream are evaluated by sediment fingerprinting techniques. The grazed areas of the floodplain are identified as the primary source of fine suspended sediment within the headwaters of the Sangamon River. Erosion of the floodplain both by surface runoff and by streambank erosion contribute to the production of almost all fine sediment sampled within the stream system. The results are consistent both for event and aggregated samples and for large and small events. The fingerprinting results are also consistent with visible and historical evidence of active erosion of grazed areas of floodplain upstream from the in-stream sampling location. Evidence from field reconnaissance and inspection of aerial photography supports the conclusion that cattle grazing plays an important role in accelerating floodplain and streambank erosion. The relationships between rainfall, discharge, and suspended sediment concentration are examined by sediment rating curve approach and hysteresis analysis. Sediment rating curves developed for three sites along the Sangamon River all have a peaked pattern with a transition point at geometric mean of discharge, indicating suspended sediment load in the stream is far below the stream transport capacity during high flows. Spatially, suspended sediment concentrations tend to become more coincident with the seasonality of rainfall and discharge with increasing watershed size and the mean suspended sediment concentration decreases as drainage area increases. Temporally, the SRCs developed for the rising and falling limbs of hydrographs and the four sampling seasons also exhibit the same trends, suggesting that these trends are not scale-dependent. The peaked pattern of sediment rating curve is most apparent in sediment rating curve developed on discharge and sediment data collected in summer, which means the limitation of sediment supply… Advisors/Committee Members: Rhoads, Bruce L.

▼ This research collected surface (<15 cm) sediments from estuarine and coastal zones off southwestern Taiwan. Basic sediment parameters, including grain size, and total organic carbon (TOC) and total inorganic carbon (TIC) concentrations were analyzed. For heavy metals (Fe, Mn, Cd, Cu, Ni, Pb, and Zn), total metal concentrations and metal fractions separated by sequential extraction techniques were determined. This study also obtained several previously collected sediment cores in the Gaoping Canyon area that had been dated by other researchers. Results obtained in this study are used in order to understand the distribution patterns of heavy metals in coastal sediments off southwestern Taiwan, and related to regional environmental changes regarding heavy metals. The distribution of heavy metal fractions and their geochemical significances were studied. Results obtained in this study indicate that physicochemical characteristics of sediments largely affected heavy metal distribution in coastal sediments off southwestern Taiwan. Regional flow patterns contributed to the observed distribution patterns. Higher heavy metal concentrations were found in sediments collected near the Gaoping river mouth, the Gaoping Canyon and its nearby continental slope, and a narrow banded offshore region off the Anping-Tainan urban areas. These results reflect the distribution of fine-grained sediments in the studied area. Vertical profiles of heavy metals in four dated cores showed drastic increases of heavy metal concentrations since 1995-2000, and some extent of decreases during 2003-2006 in two of the cores. Although actions of environmental protection regarding heavy metal pollution had taken place in this region, decreases in sediment heavy metals were mostly attributed to episodic typhoon and possibly sediment slumping events. With the recently intensified landslides and mud flows in the upper reaches of the river that would bring upstream soils and particles to the estuarine region, leading to the decrease of metal concentrations in the Gaoping estuarine sediments, a more significant decreasing trend in sediment metal concentrations can be speculated for the future.

▼ Sediment capping is currently considered one of the most convenient and efficient risk containment strategy for conatminated sediments. Conventional capping consists of placing one or more layers of inert materials on top of the contaminated sediment, retarding the flux of the pollutants to the water body and shielding the sediments from erosion or resuspension. The introduction of adsorbent materials promotes sequestration of the contaminants onto the capping media, but aging or leaks can affect the efficiency of such a reactive-cap. In a bioreactive capping, the use of an adsorbent material suitable for microbial colonization, facilitates both sequesteration and biodegradation of the contaminant. The aim of study is to experimentally evaluate the extent to which capping media selection affects bioactivity in model capping systems. Bench top laboratory studies investigated biological activity in model systems consisting of conventional capping materials (granular activated carbon [GAC], organoclay, and sand), mineral media, pore water extracted from contaminated sediments, electron acceptors (oxygen, nitrate, sulfate and iron) and the electron donor, naphthalene (a model polycyclic aromatic hydrocarbon). Microcosms were prepared and inoculated with microbial enrichements prepared with contaminated sediments collected from a river adjacent to a former manufactured gas plant. Concentrations of naphthalene and nahAc gene (encoding a dioxygenase associated with aerobic biotransformation of PAHs), were monitored for 100. Experimental data were collected and modeled; the relative kinetic rates were used to evaluate efficiencies of the different capping materials. Results suggest that GAC was the most efficient of the capping materials tested. Data showed that naphthalene concentration decreases only in oxic sediment-cap systems during the observation time, and naphthalene decay was statistically significant in oxic microcosms prepared with GAC. Abundance of the nahAc gene was sustained in oxic microcosms prepared with GAC and sand. Within oxic sediment-cap systems, a relationship between the naphthalene mass in solution and the gene copy numbers was observed in the microcosms prepared with activated carbon. This suggests that the nature of the capping material affected the interaction between abundance of a catabolic gene (nahAc) and concentration of the substrate (naphthalene).

▼ Terrestrial organic carbon (OC) erosion, remineralization, transport through river networks, and burial in marine sediments is a major pathway of the global carbon cycle. However, our ability to constrain these processes and fluxes is largely limited by (i) analytical capability and (ii) temporal sampling resolution. To address issue (i), here I discuss methodological advancements and data analysis techniques for the Ramped PyrOx serial oxidation isotope method developed at WHOI. Ramped-temperature pyrolysis/oxidation coupled with the stable carbon (12C, 13C) and radiocarbon (14C) analysis of evolved CO2 is a promising tool for understanding and separating complex OC mixtures. To quantitatively investigate distributions of OC source, reservoir age, and chemical structure contained within a single sample, I developed a kinetic model linking RPO-derived activation energy, 13C composition, and radiocarbon content. This tool provides a novel method to fundamentally address the unknown relationship between OC remineralization rates and chemical structure in various environmental settings. To address issue (ii), I additionally present results from time-series sample sets collected on two end-member systems: the Congo River (Central Africa) and the LiWu River (Taiwan). For the Congo River, bulk and plant-wax-lipid 13C compositions indicate that a majority of particulate OC is consistently derived from downstream, C3-dominated rainforest ecosystems. Furthermore, bulk radiocarbon content and microbial lipid molecular distributions are strongly correlated with discharge, suggesting that pre-aged, swamp-forest-derived soils are preferentially exported when northern hemisphere discharge is highest. Combined, these results provide insight into the relationship between hydrological processes and fluvial carbon export. Lastly, I examined the processes controlling carbon source and flux in a set of soils and time-series fluvial sediments from the LiWu River catchment located in Taiwan. A comparison between bedrock and soil OC content reveals that soils can contain significantly less carbon than the underlying bedrock, suggesting that this material is remineralized to CO2 prior to soil formation. Both the presence of bacterial lipids and a shift toward lower activation energy of 14C-free OC contained in soil saprolite layers indicate that this process is microbially mediated and that microbial respiration of rock-derived OC likely represents a larger geochemical flux than previously thought. The results presented in this thesis therefore provide novel insight into the role of rivers in the global carbon cycle as well as their response to environmental perturbations.

▼ Unpaved roads often are a major source of sediment to streams in forested watersheds, and an increase in sediment production and delivery can adversely affect the overall health of a stream. The goals of this study were to first quantify the effects of climate and soil type on hillslope and road sediment production and delivery, and then evaluate the effects of graveling, grading, and waterbar construction on road sediment production and delivery. Sediment fences were used to collect 109 fence-years of data from water years 2008 and 2009 in the more rain dominated José Basin (800-1200 m) and 193 fence-years of data in the snow dominated Kings River Experimental Watersheds (KREW) (1485-2420 m), both located in Sierra National Forest (SNF) in California. Detailed road surveys assessed road segment characteristics and road-stream connectivity. Mean hillslope sediment production in José Basin was 3.7 x 10-3 kg m-2 yr-1, which was similar to the value of 4.1 x 10-3 kg m-2 yr-1 in KREW. Native surface road segments in José Basin had a mean sediment production rate of 1.8 kg m-2 yr-1, and the estimated total sediment production from the 67 km of native surface roads is 680 metric tons per year. An estimated 30% of the native surface road length is connected to the stream network, indicating that up to 210 metric tons of sediment may be delivered to streams each year. There was no significant difference in sediment production and delivery between road segments in the highly erodible Holland soil and road segments in other soil types. Mean sediment production for the native surface road segments in the KREW watersheds was 0.13 kg m-2 yr-1, which was more than an order of magnitude lower than the mean value in José Basin, and road-stream connectivity was only 3%. There was no significant difference in sediment production from native and gravel surface road segments in José Basin due to the high variability and the gravel segments still averaged 51% bare soil. The gravel surface segments had shorter drainage features than native surface segments, but 40% of the gravel roads were connected as they tended to be closer to streams. Graveled roads in the Providence Creek watersheds produced 0.16 kg m-2 yr-1, which was only 22% as much sediment as the native surface roads, and had 11% connectivity. In José Basin grading initially decreased the mean segment length from 65 m to 41 m, but one year after grading 22% of the waterbars had failed, leading to a 15% increase in mean segment length. Graded road segments in José Basin produced eight and three times more sediment per unit area than ungraded segments in WY2008 and WY2009, respectively, and this can be attributed to extensive rilling. Sediment production rates decreased by 40-60% from the first to the second year after grading. Sediment production and delivery from forest roads can be reduced by: 1) using more than 30% gravel cover on native surface roads, 2) minimizing grading, and 3) improving the construction of waterbars to better withstand and direct overland flow.

▼ Global studies assert that anthropogenic activity now leads to disproportionately higher rates of landscape change compared with background geomorphic processes. This study explores the relative influence of anthropogenic, glacial, and geologic processes on erosion rates (E) in the northeastern United States (NEUS) by analyzing published erosion and sedimentation data across multiple methods and timescales. I compile erosion rates and sediment yields from records of stream gauging, reservoir sedimentation, lake sedimentation, cosmogenic nuclides in stream sediment, and thermochronology. These data serve as a comparison point for quantified volumes of sediment deposited in valley bottoms as a result of European settlement in the NEUS, where glacial history may influence the availability of erodible sediment and, as a result, the relative magnitude of deposited sediment. I hypothesize that E in the formerly glaciated region will be lower than unglaciated E over last century (stream gauging and reservoir sedimentation) timescales due to the erosive power of continental glaciation and resultant thin upland soils, and that there will be an increase in E evident over the last century as a result of human influence. 499 sites with location data were compiled across the NEUS, converted to erosion rate (mm/yr) and sediment yield (Ys; t km-2 yr-1), and analyzed using statistical z-tests to determine whether the population means are significantly different. Mean E from all record types across both the glaciated and unglaciated NEUS exhibits a range smaller than one order of magnitude (0.012-0.055 mm/yr), much less variable than order-of-magnitude differences reported by other researchers comparing modern and geologic erosion, both regionally and globally. Last century timescales exhibit higher E in the unglaciated region than the glaciated region, but only reservoir sedimentation shows a significant difference in E between regions (0.012 vs. 0.055 mm/yr; glaciated and unglaciated, respectively); stream gauging E did not exhibit a significant regional difference, likely due to the large basin sizes, short measurement timescales, and disproportionate spatial distribution of the measurements. E does not increase from geologic to last century timescales: late Quaternary (lake sedimentation and cosmogenic nuclide) records consistently yield lowest E, with geologic (thermochronology) records showing the highest E in both regions, perhaps indicating the relative importance of E over timescales during which major orogenies were occurring in the NEUS. The similarities in mean E and large range of the distributions of all timescales, however, point to the relative stability of E over time in the NEUS. Advisors/Committee Members: Noah P. Snyder (Thesis advisor).

▼ Detailed hydrodynamics within the swash-swash interactions are studied based on experimental measurements. Two bores are generated using a double dam-break mechanism and interact on a 1:10 impermeable sand-rough beach. Two series of experiments are conducted. The first series is carried out to explore the overall features of swash-swash interaction. The water levels in the reservoirs and opening times between the two gates of the dam break mechanism are varied to generate a large number of different swash-swash interactions. Experimental flow depth data is measured using acoustic displacement sensors. The results are combined with estimated times of flow reversal, obtained from a model based on the nonlinear shallow water equation, to determine the type of swash-swash interaction. Two types of interactions are identified: wave capture interaction, when the interaction with the second bore occurs during the uprush of the first bore, and weak wave-backwash interactions when interaction happens during the backwash of the first bore. The second series of experiments investigates the detailed hydrodynamics of these two types of swash-swash interaction by using a combined particle image velocimetry and laser induced fluorescent system, which enables comparisons to be made between wave capture interaction, weak wave-backwash interaction and the single swash event. The results of the first series of experiments show that the relative strength of the bores at the initial shoreline and time between their arrivals determines the initial type of interaction, however the type as well as the intensity of the interaction may vary throughout the swash-zone for the same swash event. The results of the second series of experiment show that during wave capture and weak wave-backwash interactions, the fluid of the first bore is advected upwards, then mixed with the fluid of the second bore by highly turbulent vortices generated at the front of the second bore because of the relative velocity differences between the two bores. Discussions of the results obtained in the experimental study highlights that swash-swash interaction results in large shoreward local fluid accelerations and strong turbulence intensities in particular with a large vertical fluctuating component. In addition, the velocity gradients indicate that the bed shear stress also increases during interaction. All these factors indicate that swash-swash interactions have the potential to enhance shoreward sediment transport in the swash zone.

▼ The last 500-km reach of the Mississippi River is often referred to the lowermost Mississippi River (LMR). The deltaic plain of the LMR has experienced severe land loss since early 20th century. Different factors affect the deficient sediment supply, as well as morphodynamics of the entire LMR, such as sea-level rise, subsidence, canal-building associated with the petroleum industry and navigation, artificial levees that prevent flooding of the river also prevent sediment deposition on wetlands, and many more factors. Given the complex morphodynamics in the LMR region, understanding long-term (decadal-scale) variations regarding to riverbed morphology and sedimentology is, therefore, an important task in evaluating whether the LMR transfers most of its sediments. This dissertation utilized hydrographic cross-sections in the LMR between 1940s and 2010s, in order to delineate the adjustments of thalweg morphology, riffle-pool sequences, as well as the entire riverbed volumetric aggradation/degradation patterns, in response to flow regulation. As the most important construction is the ORCC (Old River Control Structures), completed in 1963. The first part of this study identified an optimal spatial interpolation for mapping the river bathymetry from cross-sectional sounding measurements. Our results demonstrate that both of Ordinary Kriging with anisotropy (OKA), Radial Basis Function (RBF) perform the best in mapping the bathymetry. By using the OKA interpolator, we generated the accurate bathymetric digital elevation models (DEM), and DoDs (DEM of Difference) between 1963 and 2013. These DoDs exhibit temporal riverbed deformation patterns; and these results reveal net degradation after the completion of the ORCS. Riverbed deformation patterns in the LMR also suggest that flood events, drawdown effect near BCS (Bonnet Carre spillway), and backwater effects, may have mainly controlled the riverbed erosion/deposition patterns. Adjustments of thalweg morphology, as well as the riffle-pool sequences were also documented in this study. The discoveries reveal that the trends between the thalweg changes and riverbed deformation are relatively similar, which suggest both these patterns are controlled by same factors. In sum, it is hoped this dissertation can further contribute to future management strategies of similar river systems. The potential impacts from sediment deficits should be considered.

▼ Massive oil spills, such as the Deepwater Horizon oil spill in April 2010, have prompted increased research and attention on the techniques available to monitor oil spills, including degradation processes, and have highlighted the limitations of existing monitoring methods. Previous research has shown the spectral induced polarization method (SIP) to be sensitive to the biogeochemical changes that occur as a result of microbial oil degradation; however, there is no research on the applicability of the SIP method under high conductivity conditions typical of coastal environments. The purpose of this study is to monitor natural attenuation of microbial oil degradation in brackish coastal sediment. Natural attenuation is of primary importance since in many instances, such as for remote and inaccessible areas, it is the only option available for remediation. This research is based on the hypothesis that biogeochemical changes due to microbially-induced processes can generate detectable SIP signals, even under high conductivity environments. Five different treatments of heavy oil contaminated sediment were run for 143 days. Results indicated that geophysical signals were more pronounced in the columns with conductivities close to the actual field conditions from where the sediments were collected. Gas Chromatography/Mass Spectrometry analysis showed decreased peaks in the chromatograms of active columns compared to control columns, as well as the appearance of metabolites, indicating degradation of the substrate (contaminant oil). The results show that SIP is sensitive to the biogeochemical changes occurring as a result of microbial oil degradation even under high conductivity conditions, indicating that it could be a useful tool to non-invasively monitor natural attenuation within brackish environments.

▼ This pilot study investigates the storage of fine sediments in the river bed of the Geul River, the Netherlands. The sediment infiltration into the gravel bed is measured at four locations in the Geul River using two different methods: a gravimetric method and a metal concentration-based method. Both methods concerned the placement of sediment traps in the gravel bed, consisting of cylindrical mesh cages with a diameter of 15 cm and a height of 10 cm. In the first method, the cage was filled with clean gravel larger than 12.5 mm (the size of the mesh openings) collected from the local river bed (with a mean gravel size of 19 mm). After two to sixty-five days, the sediment traps were removed. In the second method, the sediment traps were filled with clean gravel and 700 grams of fine sand with low metal concentrations. During the sampling period, this fine sand was contaminated by deposition of metal-contaminated fine sediment from the Geul River. After four to eight days, the sediment traps were removed. For both methods the trap is placed in a bag. The bag was pulled to the bottom of the trap when the trap was placed and was pulled up when the traps were removed to retain the fine sediment. The fine sediment was washed from the sediment traps and subsequently dried and weighed. For the second method, the zinc concentrations of the fine sand and the fine sediment collected from the sediment traps were measured using a handheld XRF analyser. The sediment flux was then calculated from the differences between the zinc concentrations in the sediment samples and the fine sand. The amount of gravel-stored fine sediment was measured with a resuspension cylinder. It was found that the mean and variation of the fine sediment deposition rates increased with stream discharge during the sampling period. Changes in the trapped fine sediment weight were related to changes in discharge. The average fine sediment flux was determined by fitting a mass balance to the measurements. Based on this flux-discharge relation and resuspension measurements, average sediment residence times were calculated. A travel time model for suspended and bed load sediment based on the probability of sediment having a certain residence time was made. It was found that it takes bed load on average 13 days to travel through a river reach of 20 km and suspended sediment 126 days. Advisors/Committee Members: van der Perk, Dr M..

▼ Nowadays the sediment becomes one significant problem to reservoir watershed and it is effect and related to reservoir operation system. As the research topic, an integrated sediment approach and impacts of climate change on reservoir sedimentation, there are three main parts demonstrated in this research that all parts are related together with sediment point of view. Annual sediment depositing volume in reservoir was estimated by general soil loss equation but the efficiency was not acceptable. The first part of this study shows that the efficiency is improved by using general soil loss equation with sediment transport model. The second part is about monitoring the sediment inflow to reservoir. The important parameter to operate the reservoir is turbidity concentration of flow into dam, in the second part the suspended sediment concentration was predicted by real time therefore the reservoir operation to release turbid flow will get more efficiency. For last part, in the next future year sediment yield and water resources on the study area were investigated by extrapolated temperature and rainfall data then the results will be useful for long term reservoir operation system. First part, the integrated sedimentation was used to model an annual depositing sediment volume in reservoir. Sediment system in watershed includes not only sediment yield but also sediment transportation along the rivers. In this study, the Geographic Information System (GIS) incorporated with sediment yield model can be assisted to enhance the evaluation estimation of soil erosion. Surface erosion on Managawa river basin is then computed with the Modified Universal Soil Loss Equation (MUSLE) and it is verified to reflect the hydrological processes to which it will be able to estimate soil losses. In the sediment transport routing module, total load equation is applied to carry sediment from soil surface erosion to deposit in Managawa dam. According to annual accumulation sediment volume data in Managawa reservoir during 1981 – 2004, the establish model and simulation results are satisfied. The efficiency of the Modified Universal Equation with sediment routing in rivers is more than the simple Modified Universal Equation. Second part, the real time suspended sediment concentration forecasting was used for monitoring the turbidity flow on the upstream of reservoir. The sediment flow into the reservoir is a factor for decision support in real time reservoir operation therefore the serious area of sediment erosion of Managawa river basin, Japan is monitored by suspended sediment gauge. The hourly suspended sediment concentration at Okumotani station; the upstream of Managawa reservoir, was monitored and estimated by the artificial neural network (ANN) model that the input data were rainfall data and its products. This artificial neural network (ANN) was calibrated and validated by using recently suspended sediment data on heavy rainfall events from December 2006 to January 2008. Choosing an appropriate neural network structure and providing…

▼ Sediment regimes, i.e., the processes that recruit, transport and store sediment, create the physical habitats that underpin river-floodplain ecosystems. Natural and human-induced disturbances that alter sediment regimes can have cascading effects on river and floodplain morphology, ecosystems, and a river’s ability to provide ecosystem services, yet prediction of the response of sediment dynamics to disturbance is challenging. We developed the Sediment Routing and Floodplain Exchange (SeRFE) model, which is a network-based, spatially explicit framework for modeling sediment recruitment to and subsequent transport through drainage networks. SeRFE additionally tracks the spatially and temporally variable balance between sediment supply and transport capacity. Simulations using SeRFE can account for various types of watershed disturbance and for channel-floodplain sediment exchange. SeRFE is simple, adaptable, and can be run with widely available geospatial data and limited field data. The model is driven by real or user-generated hydrographs, allowing the user to assess the combined effects of disturbance, channel-floodplain interactions and particular flow scenarios on the propagation of disturbances throughout a drainage network, and the resulting impacts to reaches of interest. We tested the model in the Santa Clara River basin, Southern California, in sub-basins affected by large dams and wildfire. Model results highlight the importance of hydrologic conditions on post-wildfire sediment yield, and illustrate the spatial extent of dam-induced sediment deficit during a flood. We also combined SeRFE iv outputs for the mainstem Santa Clara River with a simple recruitment model of the invasive riparian plant Arundo donax, which is prevalent in the basin. This coupled modeling approach provided an ecogeomorphic framework for predicting source and sink areas of the plant. Results for these different scenarios highlight how SeRFE can provide contextual information on reach-scale sediment balance conditions, sensitivity to altered sediment regimes, and potential for morphologic change for managers and practitioners working in disturbed watersheds.

▼ A descriptive model of bed material routing was developed for alluvial streams exhibiting sequences of pools and armored riffles. The model assumes that channel geometry, sediment transport competence and the availability of sediments for transport are all non-uniform in the downstream direction. Bedload transport is described as occurring in two relatively distinct phases. Phase I involves the transport of predominantly sand-sized bed materials over stable riffles. Phase II occurs at flows which are greater than those required to entrain riffle armor and involves the transport of riffle sediments in addition to Phase I sediments. Phase I bedload transport was sampled during three high flow events at Flynn Creek, a 2 km², third order drainage in the Oregon Coast Range and at Huntington Creek in the Wasatch Plateau of central Utah during a controlled release of water from Electric Lake reservoir. A power relationship existed between Phase I bedload transport and discharge at Flynn Creek. The relationship was consistent between storms and between years. At Huntington Creek, Phase I bedload transport correlated with discharge on the rising limb of the hydrograph, but transport rates decreased over time at constant discharge, indicating a sediment supply control over Phase I transport. Phase II bedload transport was sampled at Flynn Creek during a 1.8 year return period streamflow event in February, 1979. Bedload transport rates were closely correlated with the storage and release of bed material from the riffle at the bedload sampling cross section; transport peaks corresponded to periods of scour and large decreases in transport occurred during periods of deposition. Particle size analysis of the bed material in transport showed as much as a 12-fold increase in the transport of large (> 12.5 mm diameter) bed material during periods of riffle scour. Phase II transport, which involves rapid scour and redeposition of riffles, can be described as highly non-uniform in a downstream direction and highly unsteady at any point over time. At Flynn Creek, significant scour and redeposition of riffles can be expected to occur on an average of once every one to two years. Corresponding to the two phases of bedload transport are two processes which result in changes in the particle size composition of riffle sediments. First, the intrusion of fine sediments into the pore spaces of stable riffles dominates during Phase I transport. Second, the deposition of entirely new riffle features occurs during Phase II transport. Deposition is often associated with one or more streambed scour and fill sequences and is the direct result of instantaneous differences in sediment transport rates between different channel locations. The particle size gradation of riffles is determined primarily by bed material deposition. Sampling at Flynn Creek indicated that a riffle contains the range of sediment sizes found in transport at the time of deposition but, over all, is more coarse than the particle size distribution of sediment in transport.… Advisors/Committee Members: Beschta, Robert L.

▼ Sediment transport in a gravel-bottomed stream located in the Oregon Coast Range was studied to determine the effects of a single layer of large particles (the armour layer) located at the surface of the bed material. The bed load transport system was studied jointly with suspended sediment transport to understand the total transport system. The bed load was sampled using a vortex trough in the stream bed which transported the bed load material into a sampling pit adjacent to the stream. It was found that the armour layer controls the bed load transport system by preventing sand and finer material from the bed from being entrained in the flow unless the armouring particles are first moved. The bed load of an armoured stream can be calculated using the simplified Einstein bed load function with a representative diameter for the stability parameter equal to the particle size of armouring material at which 35% of the material is finer (D35 size) and a representative size for the transport parameter equal to the median site of bed material below the armour layer. The critical discharge for disturbing the armour layer is related to a size equal to 69% of the D65 size. The critical shear stress of the armouring material is at a minimum for a particle equal to the 0.69 D65 size. Smaller particles are hidden in the armour layer and larger particles are heavier than the critical particle. From observation of the maximum size of particles transported for various stream discharges, the Shields parameter was found to be 0.025 for a rough bed and for a transport rate of very nearly zero. The suspended sediment transport system was found to be partially related to the past history of the stream because the past history f flows and sediment load controls the ability of the armour layer to remove sand and finer material from the water in the stream or to supply these smaller particles to the water. Both the bed load and suspended load of Oak Creek are quite variable when the discharge is below the critical discharge of the armour layer. Advisors/Committee Members: Klingeman, Peter C.
