基于一维和二维动态耦合FLOOD水动力模型的漓江洪水风险分析

Flood risk analysis of Lijiang River based on one-dimensional and two-dimensional dynamic coupling FLOOD hydrodynamic model

基于漓江干流及两岸地形、断面数据,构建一维和二维动态耦合FLOOD水动力模型,并对模型率定与验证。模拟漓江天然洪水和考虑漓江上游水库联合调度作用下两岸淹没情况,对漓江干流两岸洪水进行风险分析,为漓江流域精准预报、水库防洪调度、预警、效益分析打下坚实基础。

Based on the topographical and sectional data of the main stream and both banks of Lijiang River,a one dimensional and two-dimensional dynamic coupling FLOOD hydrodynamic model is constructed,calibrated and verified.By simulating the natural flood of Lijiang River and considering the inundation on both banks under the joint operation of the reservoirs in the upper reaches of Lijiang River,flood risk analysis was conducted for both banks of the main stream of Lijiang River,which lay a solid foundation for the accurate prediction,reservoir flood control operation,early warning and benefit analysis of Lijiang River basin.
