Abstract
A BASIC program is developed to route flood discharge through a system of river channels and reservoirs. The brevity of this program and the use of an overlaid computational matrix make it suitable for minicomputer execution with 32 K of RAM. Channel hydrographs are computed by the Muskingum method; reservoir hydrographs, by the Puls method. Data input consists of routing coefficients for channels, reservoir state-discharge-storage curves, and description of network configuration. An illustrative run is discussed.
