Recent progress in the development of a SPARROW model of sediment for the conterminous U.S.

摘要: Suspended sediment has long been recognized as an important contaminant affecting water resources. Besides its direct role in determining clarity, bridge scour and reservoir storage, serves a vehicle for the transport of many binding contaminants, including nutrients, trace metals, semivolatile organic compounds, numerous pesticides (U.S. Environmental Protection Agency 2000a). Recent efforts to address quality concerns through TMDL process have identified single most prevalent cause impairment Nation’s streams rivers 2000b). Moreover, medium sequestration carbon, playing potentially understanding sources sinks global carbon budget (Stallard 1998).
