Title: Provisional Assessment of Effect of Expansive Rainwater Storage in Urbanized Area
Abstract: Rainwater storage system is one of the effective measures for preventing serious flood dameges in an urbanized area. In this paper, after discussing about the contribution of existence of the water storage to relieving extreme urban climate, a method for provisional assessment of effect of the storage system is presented. In order to get some fundamental information for a future plan of river channel construction and administrative arrangement in an urbanized catchment, a set of systematic simulations of runoff discharge in conditions of various distributed patterns of rainwater storage by using the kinematic-dynamic model are carried out.
