To provide an analyzing method and an adjustment pond capacity determination method which calculate, with satisfactory accuracy, time required for water to pass through a hollow where a water collection pipe exists.SOLUTION: An analysis method has a process of acquiring an arrangement of closed conduit drain pipes buried in the ground in a predetermined range and an arrangement of water collection pipes connecting a ground surface to the closed conduit drain pipes and for use in forwarding water to the closed conduit drain pipes from the ground surface side, a process of, based on a three-dimensional topographic data in the predetermined range and the arrangement of the water collection pipes, calculating pondage of a hollow with the water collection pipes, and a process of, based on the pondage of the hollow with the water collection pipe, a drain amount of the closed conduit drain pipes, and a predicted amount of water flowing into the hollow with the water collection pipes, calculating time required for water to pass the hollow with the water collection pipes.SELECTED DRAWING: Figure 3 【課題】集水菅が存在するくぼ地を越流するまでの時間を精度よく算出する解析方法及び調整池容量決定方法を提供する。【解決手段】解析方法は、所定範囲において地中に埋設される暗渠排水管の配置と、地表面と暗渠排水管とを接続し、地表側から暗渠排水管に水を送る集水管の配置とを取得する処理と、所定範囲の三次元地形データと集水管の配置とに基づいて、集水管が存在するくぼ地の貯水量を算出する処理と、集水菅が存在するくぼ地の貯水量、暗渠排水管の排水量及び集水菅が存在するくぼ地への水の予測流入量に基づいて、集水菅が存在するくぼ地を越流するまでの時間を算出する処理と、を含む。【選択図】図３
