An Investigation into the Effects of an External Electron Acceptor on Nutrient Cycling at the Sediment-Water Interface of the Occoquan Reservoir
… subject to accelerated nutrient enrichment from urban sources. Cultural eutrophication due to such enrichment requires the development of efficient management and remediation strategies to protect drinking water sources. This study investigates the effects of using nitrate as part of a management …

Estimating Sediment Losses Generated from Highway Cut and Fill Slopes in the Lake Tahoe Basin
… < 16 micrometers in diameter) contributions from urban stormwater. Of these urban sources, highway cut and fill slopes often generate large amounts of sediment due to their steep, highly-disturbed nature. Therefore, understanding the erosion mechanisms (rainfall-runoff and dry ravel), the …
