徒骇河流域缺水严重,水资源供需矛盾尖锐,而汛期雨量丰富且蓄滞工程较为完善,因此提出通过合理地调度使用主河道上的多级闸门来提高雨洪资源利用率以缓解供需矛盾的思路。选用MIKE11软件建立多级闸门调控下雨洪演进模拟模型,主要运用其中的水动力模型(HD)和降雨径流模型(NAM),并将两者进行耦合,设计了闸门全开、水位控制、水位差控制三种调度模式,结合典型年的选取,进行典型工况下雨洪演进模拟。基于模拟结果,利用水量调控计算方法对流域调控水量进行定量分析和比较,结果表明,通过对闸门的调度,可提高雨洪资源利用率,更大程度地解决流域水资源危机。

[Abstract]
The lack of water and the imbalance between supply and demand of water resources are both serious problems in Tuhai River Basin. However, in this basin, rainfall in the flood season is abundant, and the storage and detention engineering is excellent. Therefore, we put forward an idea to improve the utilization of rain-flood resources by properly operating the multi-stage sluices on the main channel to relieve the contradiction between supply and demand. We used MIKE11 software to establish a simulation model on rain-flood resources, coupled the hydrodynamic model (HD) and rainfall runoff model (NAM), and designed three operation modes: full-open gate, water level control, and water level difference control. We used these three modes to simulate the rain and flood process in typical working conditions. Based on the results of simulation, we carried out quantitative analysis of water regulation using the water quantity regulation calculation method. The results showed that the operation of the sluices can improve the utilization of rain-flood resources and solve the water resources crisis better.
