| Research Abstract |
The objective of this study is to evaluate the effect of pollutant load derived from combined sewer overflow(CSO) on water quality in urban coastal area after rainfall event. Then, evaluation technique of health risk in water amenity area, such as Odaiba, was developed. Based on various results of urban runoff analysis, the CSO occurrence was characterized by categorized rainfall pattern. It is possible to predict the behavior of E. coli in Odaiba area by 3-dimentional water quality model in which the tidal effect and pollutant loads from pumping station and waste water treatment plant were considered.
