KeywordsComputer, Simulation, Water supply forecasting

A new approach to developing a water supply forecasting procedure is presented. Use is made of an electronic computer programming for 20 years of records and including at least 9 variables consisting of streamflow by months, precipitation by months and antecedent streamflow at six gaging stations. Two river basins were selected to try the system, one of low elevation headwaters where rainfall is the predominant source of supply, and a second with high elevation where the source of supply is largely from melting snowpack. These basins were to represent the digital model. The general equation: Inflow minus outflow equals change in storage, was expanded and used as a basis for computation of factors for the model basin.
