内容記述
For dams in snowy regions, this paper examines the feasibility of using rainfall forecasts as a basis for “advanced water release,” i.e., release that obviates the need for emergency release by reducing the water level to below the “preliminary release” water level. The authors studied this for Hoheikyo Dam, a dam with a 134-km2 catchment area on the Toyohira River of the Ishikari River System. Operations for discharging water below the preliminary release water level were simulated for cases in which the cumulative rainfall forecast and the time-series forecast of rainfall for the next 6 hours were used for decision-making.Basing advanced water release on the combination of the two forecasts achieved the avoidance of emergency operation. Some of the study results suggest that it is necessary to increase “non-damaging discharge” and review the preliminary water release level.
