Abstract:

Floodplain management has become a topic of high national priority in recent years. Computer simulation programs, such as HEC-1 and HEC-2, have greatly increased the efficiency with which calculations can be performed once input data are properly formatted. The objective of this study was to develop systematic procedures for the conduct of river basin floodplain studies. Guidelines are presented for standardizing watershed subdivision and the collecting, processing, and storing of stream cross section, elevation, soils, land use, and other information in computer data bases. Methodologies for accessing data bases and generating input decks for computer programs HEC-1 and HEC-2 are presented. Also discussed are procedures for interfacing these two programs such that manual input requirements are minimized. Other topics addressed include the coding of bridges, the effect of reach length on computed water surface elevation, the areal and temporal distributions of rainfall, model calibration, the automated mapping of floods, and flood damage estimation. Three software routines and some pertinent reference materials are included in four appendixes. Author
