Algorithm Considerations for Evaluating Phosphorus Transport and Environmental Management Strategies Using a Grid-Based Spatial Watershed Model

Abstract

Grid-based distributed watershed modeling can be used for estimating nutrient loading and as part of a decision support system to assess nutrient runoff risk and to identify critical nutrient sources and hydrologically sensitive areas. This technical note reviews applicable phosphorus algorithms for incorporation into the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model, suggests areas of algorithm improvement, and places grid-based spatial watershed modeling analysis within a decision support system framework.
