Abstract: The purpose of this model is to provide a reliable method for obtaining the hydrograph of runoff at any selected point in a sewer system for any given rainfall. This is accomplished by simulating separately the processes involved during a rainfall: infiltration, depression storage, overland flow, gutter flow, and routing through sewers. The model has been developed by using independent hydraulic and hydrologic principles and equations, and by combining the processes sequentially. It is believed that the output of this mathematical model may be helpful in the management of existing sewer systems. It also should be useful in the design of new sewer systems. The model is intended for an urban watershed of at least several hundred acres or more in area; however, it may be applied to any size by appropriate scaling. The main input information required for the simulation of the rate of hydrologic runoff includes a rainfall hyctograph and data from topographic maps or aerial photographs, or both.
