Application Of Integrated Urban Area Flood Estimation System
Access this Article
As frequency and intensity of torrential rain increases, water disaster caused by flood has become very serious. This appears remarkable especially in urban areas where population and industry have been heavily concentrating and underground facilities have been excessively developed. Under this undesirable trend, an integrated flood control system, by which the water disaster can be prevented or mitigated, is highly expected to be devised and installed. In order to achieve this goal, methods for understanding of hydraulic mechanism causing the water disaster as well as planning of measures against it have been proposed. Kajima Corporation and Chubu University jointly developed Integrated Urban Area Flood Estimation System to evaluate outflow and drainage in urban areas under torrential rain dynamically and precisely. It has been demonstrated that several damages of the water disaster in urban areas caused by torrential rain in the past can be appropriately simulated by our system. In this paper, it is considered how our system can be applied to assess effectiveness of measures installed against flood, such as sewer systems and reservoir facilities. For Tokai Heavy Rain, which caused one of the severest damages of the water disaster in the area of Nagoya City in the Chubu Region in Japan, numerical simulations using our system are conducted under several conditions regarding sewer systems and reservoir facilities. By comparison of their computed results, such as maximum inundation water depths and serious flooded areas, it is demonstrated how their effectiveness can be shown qualitatively.
