Chesapeake Bay Watershed Model Application and Calculation of Nutrient andSediment Loadings: Appendix H: Tracking Best Management Practice Nutrient Reductions in the Chesapeake Bay Program

摘要

Nutrient reduction tracking involves: (1) accurate annual land use data, (2)annual Best Management Practice (BMP) installation or implementation data, (3) using the land use and BMP data to simulate the effect of implemented BMPs. Anuual land use and BMP data are used as input for the Phase IV Watershed Model scenarios of past, present, or projected BMP implementation conditions to calculate nutrient loads and sediment delivered to the Bay.
