Runoff Simulation for Urban Sewer System Using SWMM Combined with Computer Mapping

Abstract

In this paper, runoff simulation for urban sewer system using SUM combined with computer mapping is discussed.The method of input-output data formation for SUM is modified using computer mapping. To reduce the computation time and capacity, the effect of the simplification of sewer system on the results of simulation is examied as for EXTRAN of SUM and the comparison of the runoff computation accuracy of RUNOFF with kinematic wave model is carried out as for RUNOFF of SWMM.
