A Watershed-Scale Biogeochemical Loading Model for Nitrogen and Phosphorus
The New York State Water Resources Institutes (NYSWRI) FY2001 activity under the Federal Water Resources Research Act consisted largely of eleven research projects funded during FY1999, FY2000, and FY2001. The FY 2001 Annual Report reports on a FY2000 project and a FY 2001 project from national 104G competitions, one project from a supplemental funding source, one from the FY 1999 New York Stat...
متن کاملPhytoplankton primary production and photosynthetic parameters in reservoirs along a gradient of watershed land use
We investigated how watershed land use (a gradient of agricultural vs. forested land) relates to phytoplankton primary production (PPr) and photosynthetic parameters in 12 reservoirs in Ohio and examined spatial variation in these parameters. Shallow sites near stream inflows had higher light attenuation, total phosphorus (TP), chlorophyll, nonvolatile suspended solids (NVSS), light-saturated p...
متن کاملLaboratory-determined Phosphorus Flux from Lake Sediments as a Measure of Internal Phosphorus Loading
Eutrophication is a water quality issue in lakes worldwide, and there is a critical need to identify and control nutrient sources. Internal phosphorus (P) loading from lake sediments can account for a substantial portion of the total P load in eutrophic, and some mesotrophic, lakes. Laboratory determination of P release rates from sediment cores is one approach for determining the role of inter...
متن کاملModeling watershed-scale effectiveness of agricultural best management practices to reduce phosphorus loading.
Planners advocate best management practices (BMPs) to reduce loss of sediment and nutrients in agricultural areas. However, the scientific community lacks tools that use readily available data to investigate the relationships between BMPs and their spatial locations and water quality. In rural, humid regions where runoff is associated with saturation-excess processes from variable source areas ...
متن کاملEffects of Rainfall and Runoff Variables on Phosphorus Loss in a Forest Watershed, Iran
Suspended sediment resulted from distributed soil erosions facilitates nutrient transportation and influences soil depletion. Phosphorus (P) is one of the major limiting nutrients controlling eutrophication of surface water. Irregular P load pulsed by heavy rainfall may damage the ecological quality of downstream waters. P transport study during rainfall events is important in both predicting a...
