ARan and interpreted a topographic based watershed model. Inputs included: precipitation, evapotranspiration, temperature, and calibrated flow time series; soil properties derived from SSURGO/STATSGO, hydrographs derived from ArcHydro and Spatial Analyst. Determined a relationship between nitrate/phosphate discharge and saturation deficit/base flow index for various catchment basins in the Chesapeake Bay watershed. Work also included multiple regression analysis and presentation.
