Abstract:
The Watershed model is an application of HSPF (Hydrologic Simulation Program - Fortran ) run on a unix workstation. The model divides the 64,000 square mile Chesapeake Bay drainage basin into 87 model segments. Each segment contains information generated by a hydrologic submodel, a nonpoint source submodel, and a river submodel. The hydrologic submodel uses rainfall, evaporation, and meteorological data to calculate runoff and subsurface flow for all the basin land uses including forest, agricultural lands, and urban lands. The surface and sub surface flows ultimately drive the nonpoint source submodel, which simulates soil erosion and the pollutant loads from the land to the rivers. The river submodel simulates flow and associated pollutant loads from the land through the lakes, rivers, and reservoirs to the Bay. Model Output, stored in the online database, includes a ten year annual average of both edge-of-stream and delivered nutrient and sediment loads to the bay. Nitrogen, phosphorous, and sediment (NH3, NO3, ORGN, TN, PO4, ORGP, TP, TSS) loads are estimated from agricultural, urban, and forested lands, as well as from point sources, septic, and air deposition. The database provides modeled nutrient and sediment load data under different management scenarios for the purpose of developing tributary strategies.

Attribute_Accuracy_Report:
The model accuracy can be assesed through the calibration results which can be found at http://www.chesapeakebay.net/temporary/mdsc/index.htm The model is believed to be accurate and is approved for use in setting tributary strategies to meet nutrient and sediment reduction goals of the Chesapeake Bay Program and its partners. See model documentation for completeness of the model documentation.
