A Study for a Reasonable Application of the SWMM to Watershed Runoff Event Simulation

摘要: Rainfall runoff process differs depending on if it occurs in a rural area or an urban area. While surface flow is dominant area, groundwater also important. However, Korea, most studies for watershed event simulation by the storm water management model (SWMM) have used only module regardless of characteristics basin. The purpose study to evaluate application results SWMM and suggest necessity considering basin simulation. Two basins, which can represent areas, are selected: Guro 1 Pumping Station Basin Milyang Dam Basin. Watershed simulations were conducted including derived automatic calibration. calibration quite similar observed hydrograph, even when not included. On other hand, poorly done considered. When we calculated hydrograph with Basin, well fitted into data. Thus, should be considered SWMM.
