Urban floods occur frequently in Japan. In order to reduce the risk of urban floods, the traditional method of river development should not be overemphasized. It is important to consider measures that integrate river and sewer system, as well as measures that take into account the river basin. In order to accommodate this wider scope, external factors such as rainfall need to be reasonably configured and a new model called Integrated Urban Area Model, which models complicated urban runoff and floods, is necessary. This paper reviews research on the method of setting design rainfall and the Integrated Urban Area Model, and presents future direction.
