为了管理超过设计水位的洪涝灾害，在适当的风险评估的基础上进行洪水风险控制至关重要。在洪水灾害综合经济风险评价中，洪水风险曲线是洪水淹没损失与其超越概率之间的关系，具有重要的作用。通过降雨径流和洪水模拟，利用年最大降雨量的概率分布函数，建立洪水风险曲线，以便风险评估能够考虑气候和社会经济变化。在各种不确定性中，本研究提出的方法考虑了时空降雨分布对损失估计具有较高的不确定性。将该方法应用于日本Yura-gawa流域(1882km2)，通过比较有、无大坝的洪水风险曲线，成功地量化了该流域现有大坝的年经济效益。
To manage flood disaster with an exceeding designed level, flood risk control based on appropriate risk assessment is essential. To make an integrated economic risk assessment by flood disaster, a flood risk curve, which is a relation between flood inundation damage and its exceedance probability, plays an important role. This research purposes a method to develop a flood risk curve by utilizing a probability distribution function of annual maximum rainfall through rainfall-runoff and inundation simulations so that risk assessment can consider climate and socio-economic changes. Among a variety of uncertainties, the method proposed in this study considered spatio-temporal rainfall distributions that have high uncertainty for damage estimation. The method was applied to the Yura-gawa river basin (1882 km 2 ) in Japan; and the annual economic benefit of an existing dam in the basin was successfully quantified by comparing flood risk curves with/without the dam.
