▼ 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.

▼ 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.

▼ 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 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.

▼ Föroreningar av metaller är ett problem längs med kusterna, vilket har en negativ inverkan på vattenlevande organismer och miljön. Orsaken till detta beror till stor del på pågående utsläpp från tätorter, hamnar, industrier och på ”gamla synder (då det inte fanns några detaljerade miljölagar som reglerade spridningen av föroreningar från exempelvis industriprocesser)”. Utsläpp av föroreningar behöver inte bara komma lokalt utan kan också transporteras via avrinningsområdena och via atmosfäriskt nedfall. Idag arbetar länsstyrelsen med att invertera och sanera förorenade områden, men för att kunna ta reda på hur det ligger till med kusterna och hamnarna är sedimentprovtagningar ett måste. Att analysera data från sedimentprover kan vara speciellt utmanande eftersom det finns många olika faktorer som kan ha betydelse när data skall analyseras. Det kan vara faktorer som bottentyper, utspädning, kornstorlekar mm i en miljö som är speciellt utsatt för omrörningar. Syftet med detta arbete är att identifiera åtgärder som kan bidra till att förbättra analysen av föroreningar från sedimentundersökningar då det finns faktorer som kan påverka föroreningssignalen. Till detta arbete har data från Sveriges Geologiska Undersökning (SGU) använts. Provtagningarna genomfördes längs med kusten i Kalmarsund under åren 1998, 2003 och 2008. Dessa data har tidigare studerats med fokus på metallkoncentrationer. I detta arbete ligger fokus istället på att göra fördjupande jämförelser genom att studera morän, organiskt material, samt tillämpningen av normaliseringar och elementförhållanden. Även data från Structor Miljö Göteborg AB som tagit prover i Oskarshamns hamn under 2011 med hjälp av sedimentfällor har använts. Syftet är att göra en jämförelse med SGU:s provtagningar, samt att undersöka miljögiftsbelastningen och sedimentationshastigheten i Oskarshamns hamn och ytterområde. Resultatet visar att spridningen av metaller kan förbättras genom att studera koncentrationerna tillsammans med organiskt material, normalisering mot organiskt material och naturliga utsläpp av metaller ifrån morän. Resultatet visar också att sedimentfällor är ett utmärkt komplement till vanliga sedimentprovtagare.

▼ 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.

▼ 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.

▼ 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..

▼ According to the US Environmental Protection Agency (USEPA) sediment is a leading cause of water quality impairment (US EPA, 2002). The annual costs of sediment pollution in North America alone are estimated to range between 20 and 50 billion (Pimentel et al., 1995; Osterkamp et al, 1998, 2004). Due to the large spatial and temporal variations inherent in sediment transport, suspended sediment measurement is challenging. The overall goal of this research was to develop and test an inexpensive sensor for continuous suspended sediment monitoring in streams. This study was designed to determine if the gain and phase components of permittivity could be used to predict suspended sediment concentrations (SSC). A bench-scale suspension system was designed and tested to guarantee that there were no significant differences in the sediment suspension vertically or horizontally within the system. This study developed prediction models for SSC with input variables of temperature, specific conductivity, and gain and/or phase at multiple frequencies. The permittivity sensor is comprised of an electrode, power source, and a control box or frequency generator. Fixed and mixed effect, multiple, linear regression models were created and compared for target frequencies. However, it was not possible to meet the normality requirements for prediction accuracy. Partial Least Squares (PLS) regression techniques were also applied to gain and phase data for 127 of the 635 frequencies. The three models with the lowest error between predicted and actual values of SSC for validation were further tested with nine levels of independent validation data. The largest model error (error>50%) occurred for the top three models at 0 and 500 mg/L. At the higher concentrations error varied from 1-40%. Once the treatment levels, of the independent validation data set, were near 1000 mg/L the prediction accuracy increased for the top three models. Model 3A, a phase based model, preformed the best. Model 3A was able to predict six of the nine independent validation treatment levels within 300 mg/L. Future research will provide additional laboratory and field testing of the prototype sensor.

▼ 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…

▼ Flow and sediment regimes are two of the main abiotic factors driving riverine ecosystems, interacting at different temporal and spatial scales. These interactions have a strong influence on habitat composition, ecosystem processes and community composition. Nowadays, flow and sediment regimes are highly altered due to anthropogenic modifications of rivers and floodplains, such as dams or river channelization, which disrupt the main properties of both regimes. The primary goal of this thesis was to understand the role of flow and sediment interactions on ecosystem structure and function in managed rivers and evaluate different techniques that mitigate the impact of rivers regulation. Hyporheic sediment respiration, periphyton biomass and chlorophyll-a were used as indicators of ecosystem function, whereas macroinvertebrates assemblages were used as a structural indicator. The first chapter studied the variability of different indicators of ecosystem structure and function under different flow and geomorphology conditions. The study took place in a section of the river Thur, where a widening restoration was implemented by removing 1 km of lateral protections. This widening section characterized by newly established habitats such as gravel bars is fringed upstream and downstream by channelized sections. Channelized sites showed higher rates of sediment respiration, periphyton and macroinvertebrates compared to restored sites. Restored sites showed a greater temporal and spatial variability in the measured indicators due to the influence of flow disturbance, which was lower in channelized sites. Overall, sediment respiration and macroinvertebrate richness were related to flow variability and geomorphology, whereas periphyton and macroinvertebrate density was influenced mainly by flow variability. The second chapter investigated the influence of flow regulation (residual flows and hydropeaking) on aquatic life stages that can persist in sediments during dry phases (i.e. macroinvertebrate seedbanks). Gravel bars affected by hydropeaking showed greater densities of organisms due to the high frequency of inundations, which increased the drift of animals onto gravel bars. The opposite trend was found in residual flow rivers, where there is a lack of flood occurrence. The third chapter assessed the ecological impact of a Sediment Bypass Tunnel, a structure that routes upstream sediment input around dams, reducing the accumulation of sediments in the dam. Operations of the tunnel create a general decrease in measured indicators (sediment respiration, periphyton and macroinvertebrates), the decrease being related to the magnitude of flow and sediment released at the tunnel. The fourth chapter described the interactions of flow and sediment inputs in two rivers with contrasting management programs (experimental floods and sediment bypass tunnel). Sediment lateral inputs caused local interactions with flow, generating morphological and biotic heterogeneity in the streambed, whereas upstream sediment inputs… Advisors/Committee Members: Robinson, Christopher T., Jokela, Jukka, Jähnig, Sonja.

▼ Dams on rivers alter the sediment continuum, trapping water and sediment in the upstream reservoirs. River reaches downstream are affected by several negative effects, such as bed incision, reduction of the river morphological variability, development of an armoured layer and depletion of ecological habitat for fish. The replenishment of sediment technique has been used since the 1970s to mitigate the lack of sediment transport in the downstream reaches of dams. The method is mainly used to re-establish a sediment continuum, restore a natural bed morphology and to recover spawning grounds for fish. Even if both experimental and field tests have been performed in the past, there is still a lack of knowledge regarding the necessary flow released from the bottom outlet of the dam, the amount of sediment and the configuration of the replenished deposits. This research aims at filling these gaps by means of experimental tests at the Laboratory of Hydraulic Constructions at Ecole Polytechnique Fédérale de Lausanne (EPFL). The main characteristics of an alpine stream were reproduced in a channel facility in terms of grain size distribution, slope and hydraulic conditions. The sediment replenishment technique was investigated as an influence to the geometrical configurations and volume of deposits, as well as applied discharge. The experiments showed that the bed morphological pattern created by the eroded replenishment material was linked to the initial geometrical arrangement of the replenishment volumes. When applying parallel configurations of replenishment volumes, a general bed fining was obtained with material spread over the entire channel width. Alternating replenishment positioning lead, in turn, to the creation of bed morphological patterns. The wavelength of these bed forms was seen to be related to the replenishment length. Both constant discharge and transient flow were investigated. Three submergence conditions of the replenishment were tested: unsubmerged, completely submerged and over-submerged. A complete submergence was optimal to obtain a complete erosion of the volumes with transport of the material along the channel and persistence of the material on the channel bed. Four slopes for the increasing and decreasing limb of triangular-shaped hydrographs, having the same maximum discharge, were tested and the results compared with the constant discharge cases. A discharge having a triangular distribution in time is similar to the operational condition of dams when releasing an artificial flood. Transient flows with steep rising limbs lead to a reduction of 70% of water consumption compared to a constant flow, although achieving the erosion of the replenished material. The application of the complete hydrographs showed to be counter-productive in terms of local effect of the sediment replenishment. These hydrographs may be useful for reaching longer distance impacts in sediment replenishment. Lastly, the effect of consecutive replenishment of sediments was investigated. A second replenishment can… Advisors/Committee Members: Schleiss, Anton, Rodrigues Pereira Da Franca, Mário Jorge.

▼ I seek to reconstruct the balance between sediment storage and yield across multiple drainage basin scales in a large (1 230 km2) watershed in the Northern Cascade range, British Columbia and Washington. Chilliwack Valley and surrounding area has been the site of numerous studies that have detailed much of its Quaternary sedimentary history. In the present study this information is supplemented by reconstruction of the morphodynamic trajectory of the river valley though the Holocene Epoch, and development of a sediment transfer model that describes the relaxation from the Fraser glaciation. The total Holocene sediment yield is estimated from basins across several scales using field and remotely sensed evidence to constrain the historical mass balance of delivery to higher order tributary basins. Rates of hillslope erosion are estimated using a diffusion-based relation for open slopes and delimitating the volume evacuated from major gully sources. Digital terrain models of paleo-surfaces are constructed to calculate total sediment erosion and deposition from tributary valleys and the mainstem. Chilliwack Lake has effectively trapped the entire post-glacial sediment load from the upper catchment (area = 334 km2), allowing to compare this "nested" system with the larger catchment. Rates of lake sediment accumulation are estimated using sediment cores and paleomagnetism. These are compared with accumulation rates in the terminal fan inferred from radiocarbon dating of fossil material, obtained by sonic drilling in the apex gravels. A sediment budget framework is then used to summarize the net transfer of weathered material and glacial sediments from the hillslope scale to the mainstem. The long-term average sediment yield from the upper basin is 62 +/- 9 t/km2/yr; contemporary yield is approximately 30 t/km2/yr. It is found that only 10-15% of the material eroded from the hillslopes is delivered to mouths of the major tributaries; the remaining material is stored at the base of footslopes and within the fluvial sedimentary system. Since the retreat of Fraser Ice from the mouth of the valley, Chilliwack River delivered over 1.8 +/- 0.21 km3 of gravel and sand to Vedder Fan in the Fraser Valley. In the sediment budget developed here, roughly 85% of that material is attributed to glacial sources, notably the Ryder Uplands and glacial valley fills deposited along the mainstem, upstream of Tamihi Creek. In tributary valleys, local base-level has fallen, leading to the evacuation of deep glacial sedimentary fills. Many of the lower reaches of major tributaries in upper Chilliwack Valley (e.g. Centre and Nesakwatch Creeks) remain primarily sediment sinks for slope-derived inputs, since base-level fall has not been initiated. In distal tributaries (Liumchen, Tamihi and Slesse creeks), paraglacial fans have been incised or completely eroded, entrained by laterally active channels. A transition from transport-limited to supply-limited conditions has been effected in many of these reaches. Slesse Creek has struck an intermediate…

▼ Sediments have been recognised as an important source and repository for many contaminants that enter the aquatic environment. In addition to influencing surface water quality, contaminated sediments also represent a potential hazard to benthic biota and the aquatic food chain. Accurately defining the extent of environmental risk posed by sediment-associated contaminants is becoming an important priority for regulators and industries worldwide. Sediment quality guidelines (SQGs) are intended to delineate between sediments that cause adverse biological effects and those which do not. In the case of metals, however, an absence of toxicity is frequently observed in sediments with metal concentrations many times greater than the SQG trigger values. Factors that modify metal partitioning between dissolved and particulate phases in sediments (e.g. particle size, organic carbon, sulfide, pH) and thereby influence metal bioavailability and toxicity are believed to be responsible for the disparity. Further, the significance of exposure pathways (dietary particle ingestion and dissolved metal uptake) to a range of representative benthic organisms must also be understood to derive SQGs that offer protection for a full range of organism behaviours and benthic habitats. Laboratory-based experimentation was undertaken to assess the sensitivity of benthic organisms to copper in sediments and the appropriateness of current SQGs for copper. Detailed information was obtained on the equilibration of copper-spiked sediments and the influence of sediment properties on the partitioning of copper between different sediment compartments (solid phases and dissolved copper in the pore water and overlying water) before and during tests. The research focused primarily on acute toxicity to sediment-dwelling estuarine and marine organisms, including the epibenthic amphipod, Melita plumulosa and the bivalve, Spisula trigonella, for numerous sediments with varying metal-binding properties. The 10-day acute EC50s of the particle-ingesting amphipod varied from 200 to 20,000 mg/kg for sediments with copper-binding affinities ranging from low (sandy) to very high (mineralised). Similar patterns of acute toxicity across the varying sediment types were observed for the bivalve, despite having a dissolved metal uptake exposure pathway. Of the factors expected to influence copper binding, elevated acid-volatile sulfide, was demonstrated to temporarily ameliorate the bioavailability of copper, and sediment pH had a minor effect on dissolved copper toxicity. Far more influential were the sediment particle size and organic carbon content. Concentration-response relationships based on the total particulate copper and organic carbon (POC) concentrations of the less than 63 μm sediment fraction effectively normalised the influence of sediment properties on the measured copper effects threshold for all sediment-types tested. Acute and chronic effect thresholds were derived (14 and 3.6 mg Cu/g POC, respectively) using a…
