The rainfall-runoff transfer has been simulated by linear, nonlinear, time invariant and time variant deterministic models. Most of these models, particularly those based on the linear analysis concept, use the rainfall excess as the input. The weakest link in the rainfall-runoff transfer models is the proper estimation of the input, the effective rainfall. The principal objective of this study was the development and testing of methods of estimation of the rainfall excess. The other objectives of the study were the testing of linear and nonlinear systems models in the determination of the response of watersheds at different stages of urbanization and the development of a model of the rainfall excess-direct runoff transfer.
