In snowy regions, the water storage capacity in the soil as well as in the snowpack must be properly evaluated. This paper estimates the water storage capacity of a watershed using a long-term hydrologic processes model and then examines the relationship between rainfall and inflow to the dam reservoir for heavy rainfall events. We found that the reproducibility of the flood runoff model can be improved by incorporating water storage. Accordingly, quantifying the water storage capacity of a watershed is of practical use for predicting flood runoff and releasing water from a dam reservoir prior to a flood event to improve the dam’s flood control capacity.}, pages = {487--492}, title = {流域の貯留量を考慮したダムの洪水調節機能の改善策について}, volume = {54}, year = {2010}, yomi = {オオハシ, カズヘイ and ナカツガワ, マコト and ウスタニ, トモヒデ} }
