Risk and benefit analysis of multifunctional reservoir staged operating

An optimal flood-limiting water level (FLWL) is needed to solve the contradiction between flood control safety measures and utilizable benefits. Therefore, this paper took the Chengbi River reservoir as an example, applied the Monte Carlo stochastic simulation and water consumption rate per unit of...
