水库防洪可分为两类,即综合利用水库承担防洪任务和专用于防洪的水库。水库根据下游防洪需要及统一的防洪规划,可以合理调蓄入库洪水,降低出库洪峰流量,拦蓄下游成灾水量,错开下游洪水高峰,使下游防洪保护地区的河道水位(或流量),保持在保证水位(或河道安全泄量)以下,以保证防洪安全。承担防洪任务的水库常与其防洪设施一起,共同组成防洪系统,担负防洪任务。水库的防洪调度方式,要安全可靠,以确保下游防护对象达到既定的防洪标准以及大坝自身的防
Reservoir flood control can be divided into two categories, namely, comprehensive utilization of reservoirs to undertake flood control tasks and flood control reservoirs. According to the need of downstream flood control and unified flood control plan, reservoirs may reasonably regulate storage and storage of floods, reduce discharge peak flow and intercept downstream disaster-caused floods, and stagger downstream flood peak so as to keep the water level (or discharge) of rivers in downstream flood control areas In ensuring the water level (or river safety relief) below, in order to ensure flood safety. The reservoirs undertaking flood control tasks often work together with their flood control facilities to form flood control systems and undertake flood control tasks. The flood control and dispatching methods of reservoirs should be safe and reliable to ensure that downstream protection targets meet the established flood control standards and the dam’s own defense
