Abstract

Storm Water Management Model (SWMM) is a widely used software for designing and analysing the performance of urban drainage systems. The software simulates the reaction of drainage systems to precipitation. When the stormwater network includes open channels and ditches, the groundwater level may significantly affect the water levels and flow within these systems. However, as the availability of information on groundwater is scarce and the direct measurement challenging, calibration of it is a demanding task. Herein a method that utilizes SWMM’s Unit Hydrograph feature is suggested for distinguishing groundwater flow from the rest of the runoff. This approach allows to significantly decrease the time needed for calibration.
