The research developed methods for a numerical simulation of watersheds which will be both operational from the standpoint of engineering usage and realistic from the standpoint of simulating physical processes occurring in the watershed. The Stanford Watershed Model has been reviewed and used as a pattern for developing a new watershed simulation model. The new model incorporates considerable flexibility of input data and model time steps which were not available in the Stanford Model. In making a detailed translation of the model into Fortran IV compiler language, a nearly complete understanding of the model was achieved and has been presented as a part of the report. New parameters describing the infiltration, evaporation, and soil water movement processes have been defined and related to physical properties of the watershed where possible. Application to two experimental watersheds are reported. (Author)
