To provide a reservoir collapse determination method or the like, capable of evaluating the risk of a disaster caused by the inflow of sediment into a reservoir.SOLUTION: A reservoir collapse determination method for determining a possibility of the collapse of a reservoir due to an inflow of sediment, includes the steps of: calculating an inflow amount of sediment that can flow into the reservoir based on information about a terrain around the reservoir; calculating an overflow water depth or a fluid force of a dam body at which a water level of the reservoir rises due to the inflow of sediment into the reservoir; and determining whether or not the collapse of the reservoir has occurred based on the calculated overflow water depth or fluid force.SELECTED DRAWING: Figure 5 【課題】貯水池への土砂の流入に起因する被災のリスクを評価可能な貯水池決壊判定方法等を提供する。【解決手段】土砂の流入による貯水池の決壊の可能性を判定する貯水池決壊判定方法は、貯水池の周辺の地形に関する情報に基づいて、貯水池内に流入する可能性のある土砂の流入量を演算する工程と、貯水池内への土砂の流入に起因して該貯水池の水位が上昇する堤体の越流水深又は流体力を算出する工程と、算出された越流水深又は流体力に基づいて、貯水池の決壊の発生の有無を判定する工程とを含む。【選択図】図５
