An inundation flow model including sewerage system for the low-lying river basin is developed in this study. This model is applied to the Neya River basin, Japan, a highly urbanized area. There are flood control facilities such as flood control zones and underground regulating ponds, which are also considered in the simulation. From the obtained results, it is concluded that this model can express the inundation process in the low-lying urban area by heavy rainfall and can support to estimate the effectiveness of those flood control facilities.
