Sediment Sources and Transport in the Chesapeake Bay Watershed
Prepared by Allen C. Gellis and John W. Brakebill, U.S. Geological Survey (March 2013)Sources, Fate, and Transport of Nitrogen and Phosphorus in the Chesapeake Bay Watershed—Interpretations and Applications of Spatially Referenced Regression on Watershed Attributes (SPARROW) Nutrient Model Results
As the largest and most productive estuary in North America, Chesapeake Bay is a vital ecological and economic resource. The bay and its tributaries have been degraded in recent decades, however, by excessive inputs of nutrients (nitrogen and phosphorus) and sediment from contributing watersheds. In 2000, the bay was listed as “impaired” under the Clean Water Act, and in 2010, a Total Maximum... - Data
