Flood Prevention and Pollutant Reduction by Real Time Control of Urban Stormwater Storage System with Predicted Rainfall Information

Recently, some localized heavy rainfall events which are especially affected by global climate change causing urban flooding has brought a lot of disaster. On the other hand, urban river water pollution derived from non-point source distributred with urban surface has been becoming relatively important after point source pollutant reduction. In this study, effectiveness of the real time control (RTC) of urban storage system for both purpose of flood prevention and pollutant reduction is estimated by continuous simulation with prediction of the latest RADAR precipitation system..Recently, some localized heavy rainfall events which are especially affected by global climate change causing urban flooding has brought a lot of disaster.
