河川の機能評価による脆弱箇所の抽出と維持管理目標の設定に関する検討

抄録

For responding to urgent river flood and levee disaster, it is essential for river administrator to comprehend the vulnerable place beforehand. We study the practicable method to extract that for overtopping, piping, sliding by integrating ready-made methods of verification used for planning and designing. Overtopping, piping and sliding are principally caused by precipitation and water level on-site. So we describe the measure of analyzing with several scenario, and evaluating vulnerability by simulating water surface profile and the piping-and-sliding characteristic curve. In addition, we point out that these methods can configure functional objectives quantitatively.
