Abstract

A computer model for calculating flood hydrographs from storm rainfall on natural and urban catchments is described. The computer program is specifically designed for engineering flood studies, and includes data checking and verification procedures. All results are written to an output file for QA records. Features of the model include separate calculations for hydrographs from pervious and impervious surfaces, and separate calculation of overland flow hydrographs and stream channel hydrographs. Flood routing in mainstream and onsite detention flood storages is included. Built-in relations allow elevation-discharge relations to be calculate
