本文介绍了一个集成模型的开发，径流/洪水淹没模拟和经济损失估计，特别是关注，日本兵库县的佐代镇，有一个严重的洪水灾害，由于2009年8月9日至10日的强降雨事件。首先，利用日本气象厅的复合雷达和雷达-AMeDAS再分析数据，结合地面观测数据，分析了当时沙耶川流域的降雨量。其次，利用雷达-AMeDAS再分析资料，利用集成模型模拟了径流和洪水淹没过程。模拟的淹没面积与淹没记录吻合较好。然后，根据模拟的淹没面积和淹没深度进行了经济损失估算，并与市政府上报的预测值进行了比较。房屋/建筑物的经济损失估计为204亿日元，与报告的185亿日元相当吻合。
This paper deals with the development of an integrated model for rainfall-runoff/flood inundation simulation and economic loss estimation, especially focusing on Sayo Town, Hyogo Prefecture, Japan where there was a severe flood disaster due to a heavy rainfall event on 9-10 August 2009. Firstly, the rainfall over the Sayogawa river catchment at the time is analyzed by using the composite radar and Radar-AMeDAS reanalysis data by the Japan Meteorological Agency in addition to the ground observation data. Second, the rainfall-runoff and flood inundation processes are simulated using the integrated model with the Radar-AMeDAS reanalysis data. The simulated inundation area shows the good agreement with the inundation record. Then, the economic loss estimation based on the simulated inundation area and depth is carried out and compared with the prospected value reported by the municipal government. The house/building economic loss estimated is 20.4 billion Japanese Yen, which agrees well with the reported value 18.5 billion Japanese Yen.
