Computer simulation of subprocesses in the hydrological cycle is very attractive for engineering applications. Three such simulation models were designed and are presented with a few practical applications. The first model synthesizes seasonal point precipitation for State College, Pennsylvania. This model was used to extend a 27 year historical precipitation record to a record for 54 years. The second model generates precipitation events which cause hydrograph peaks with return periods of 2 years or more. The third model attempts to translate precipitation into stream flow. The last two models were used to calculate peak flow rates with specified return periods on two small catchments. The stream flow model was also used to simulate daily stream flow from historical precipitation records on a medium-sized catchment and to calculate the seasonal increase in stream flow which can be obtained by means of artificially increased precipitation. With small modifications these models may find wide use in South Africa.
