Evaluation on an on-site stormwater treatment device for sediment flux mitigation in the Lake Tahoe basin
… water runoff, which includes pollutants such as sediment, nutrients, metals, microorganisms, and organic compounds. Sediment is of particular importance because many pollutants are readily 5 adsorbed onto particles. In the Lake Tahoe basin, sediment is also significant because of its direct …

Hydraulic Performance of Porous Sediment Control Structures
… of filter fabric and rockfill as well as their sediment trapping efficiency are studied in this research. The head-discharge relationship for filter fabric has been developed by first applying the Bernoulli equation to a single opening and then extending the principle to the entire …

Plant communities in field margins of agricultural landscapes: species distributions, functional traits, and contributions to landscape function
… management schemes at different slope degrees on sediment trapping. To test how the local management “managed and unmanaged” and the landscape-scale land-use “percentage of non-farmed habitat” influence plant communities of agricultural field margins, we studied multi-facet plant community …

Keeping Pace with Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit along the Louisiana Coast
… of the Mississippi Delta receive just 30% of the sediment necessary to sustain current land area1. An extensive monitoring campaign by the USGS and LCPRA provides direct measurements of sediment accumulation, subsidence rates, and deposit characteristics along the coast over the past 10 years2, …

Recovery status of a cypress (Taxodium distichum)-water tupelo (Nyssa aquatica) wetland seven years after harvest disturbance
… and least in the reference area (1495 kglha). Sediment accumulation reflected these differences in groundflora biomass; 104 mm in the herbicide controlled treatment, 79 mm and 63 mm in the helicopter logged and skidder simulation treatments, respectively, and 37 mm in the reference area. Three …

Geoprocessing Approaches to Delineate Impoundments and Characterize Subcatchments within Kansas Reservoir Drainages
… of impoundments to act as significant sinks for sediment. However, their significance within Kansas reservoir drainages and potential service in mitigating downstream reservoir sediment yields is not well understood. This thesis seeks to improve understanding of small impoundments distributions …

Reservoir sedimentation in dryland catchments : modelling and management
… strongly on storage in surface reservoirs and sediment deposition in these reservoirs affects adversely the water storage. In order to reproduce the complex behaviour of sediment deposition in reservoirs located in semi-arid environments and the effects of using sediment management techniques, …

Simulating Anthropogenic and Climatic Influences On Fluvial Sediment Load In the Southeastern U.S. and Central Europe
<p>Quantifying variable riverine sediment discharge over time in response to climate and human pressure is crucial to understanding past, present and future patterns of sediment flux to the worlds' oceans. The need for this data is critical in light of changing anthropogenic activities, global …
