Analysis of Flooding Water Over a Crowded Urban District and Attempts at Innundation Water Control

Abstract

The spread of flooding water in a crowded urban district was simulated by incorporating prorerly houses, roads, and land information in the two-dimensional numerical model. It was shown by this numerical simulation that the time of flooding water advancement was mainly controled by the road network. It was also found by the model that the decrease in the innundation area and water depth became possible by setting drainage gate and tree zones, and raising the level of roads at appropriate places.
