Application of a Geographic Information System to Rainfall-Runoff Modeling

Abstract

The planning of water resource projects relies heavily on geographic information describing river basins. Information about topography, land use, vegetative cover, soil type and erodibility are needed in rainfall-runoff modeling, flood damage determination, soil erosion studies, and water quality studies. Geographic Information Systems (GIS) have been developed to take advantage of the data handling capability of digital computers for storage and use of geographic information. With a GIS, less averaging is required and greater use of readily available physical data is accomplished. The computer program system, HEC1-ADAPT, combines two existing models. ADAPT is a GIS that was originally developed by W.E. Gates and Associates to aid in sewer design. HEC-1 is a rainfall-runoff model that was developed at the Hydrologic Engineering Center of the Corps of Engineers. These two modeling systems are linked together to provide a GIS-based watershed-runoff capability. This report describes the testing of the HECI-ADAPT system for rainfall-runoff modeling.
