AN AUTO‐CAD‐BASED WATERSHED INFORMATION SYSTEM FOR THE HYDROLOGIC MODEL HEC‐1 1

摘要: : A micro computer based Watershed Information System (W.LS.) is developed to assist in the preparation of input files for hydrologic simulation model HEC-1. This system consists three phases. Phase I utilizes capabilities AutoCAD version 9 and programs, BASINS, PLANES, CHANNELS, extract, organize, display watershed data. II uses program CN calculate some HEC-1 parameter values. HECUPDATE create files. The includes topographic, soils, land use, geometry data, a skeletal file. Output from summary User Reference File, Soils Land Use Geometry Curve Number file, which ready run. W.I.S. has been applied Macks Creek southwest Idaho.
