摘要
从提高水库洪水资源利用的角度,运用相对频率法对丹江口水库的汛期流量资料进行统计分析,获悉汛期不同时段的入库洪水分布规律和发生概率,并结合水库调洪演算,初步确定以旬为控制时段的水库分期汛限水位,能够在不增加防洪风险的前提下充分发挥水库在汛期和汛末的兴利效率。
According to ever increasing the utilization of floodwater and in combination with flood regulation, the flood control water level of Danjiangkou Reservior per ten-day mean during flood season was statistically analysed by using the relative frequency theory and combining flood regulation. For taking ten-day as control time-interval of reservoir stage flood control water level, the Danjiangkou Reservoir can greatly improve economic benefit, without increasing risk of flood control standards during flood period and the post-flood season.
