Owing to overflows from combined sewer pipe systems, water quality of receiving waters, including urban rivers, has become worse year by year. Appropriate countermeasures that can mitigate the overflows, therefore, must be developed promptly. The authors have investigated a distributed simulation model of water qualityand stormwater runoff in urban sewer pipe systems. First, a surface routing model of stormwater and pollutants, which is a sub-model of the distributed model, is proposed. Second, the routing model is applied to a roof and a road surface of Matsuyama city and the applicability of the model is investigated on the basis of the comparisons of observed and simulated hydrographs.
