碧流河水库下游河道的现状防洪能力

Actual flood protection ability of lower river course of Biliu River Reservoir

针对缺乏实测流量资料的水库下游河道,利用一维河网模型系统MIKE11,采用多种工况组合,模拟计算并分析了碧流河水库下游河道主要断面的现状防洪能力。建模过程考虑水库调度与潮位等因素的影响:使用水库下游河道最新实测断面数据与网上遥感数据,参考设计资料,并结合计算经验综合确定计算模型参数。研究成果可为碧流河水库及其下游河道组成的联合调度系统提供决策支持。

According to the situation of practical flux data absence for some lower river course of the reservoir, the one-dimensional river network model (MIKE11) and various project-situation combinations are introduced to stimulate the condition. Based on it, the actual flood protection ability of main section in lower river course of the Biliu River reservoir is calculated and analyzed. In the process of modeling, various factors such as reservoir operation and water level of tide have been considered. The parameters of the model are confirmed by using the late practical section data and net remote sensing data, consulting with design data and combining with calculative experience. The conclusions can provide decision-making proofs for joint operation system which consists of the Biliu River Reservoir and its lower river course.
