为模拟水库溃坝,以金牛山水库为例,在分析设计洪水和水库水位多种组合下利用MIKE软件模拟了主坝溃决后洪水在下游的演进过程,获得了淹没水深、淹没范围及流速等洪水风险信息,为金牛山水库下游防洪决策提供了依据。 Taking Jinniushan Reservoir as an example, MIKE software is used to simulate the evolution of the flood downstream of the main dam after the collapse of the main dam to simulate the dam breakage of the dam. Taking the Jinniushan Reservoir as an example, the submerged depth, submerged range and velocity of flow are obtained by simulating the design flood and reservoir water level. Flood risk information provides the basis for flood control decision-making in downstream of Jinniushan Reservoir.
