Abstract
The problem of prediction of surface flow hydrographs resulting from excess rainfall was investigated by applying response surface mapping techniques to estimate parameters as a function of time. An empirical model with two absorbing sectors (surface flow and the sum of the evaportranspiration and seepage loss) was developed and applied to a complex system of interconnected watersheds using hypothetical data and parameters. The model techniques were also applied to predict a surface flow hydrograph for a single real world watershed. (Author)
