Development of a Simple Soil Moisture Model in the Hydrologic Simulator GSSHA

Abstract

The purpose of this System-Wide Water Resources Program (SWWRP) technical note is to describe the development and application of simplified unsaturated zone modeling in the Gridded Surface Subsurface Hydrologic Analysis model (GSSHA) (Downer et al. 2005). This new method was developed to increase the applicability of the GSSHA model to high resolution coupled surface-water/groundwater simulations of large basins that may be limited by excessive simulation times or accuracy of methods of unsaturated zone computations previously available in the model.
