摘要
以海淀区北部的南沙河流域为例,采用HEC-RAS模型模拟了50年一遇洪水水文资料下的演进过程,并可视化显示水深、流速、淹没区域等信息。结果表明,该模型操作方便,计算效率较高,满足防洪规划要求,可作为洪水风险分析的理论技术支撑。
Taking Nansha river basin in the north of Haidian District for an example, HEC-RAS model is applied to simulate the process of 50-year frequency flood. And then the information of water depth, velocity and submerged area is visualization display. The results show that the model can be implemented easily and it has high computation efficiency, which meets the requirement of flood control planning. Therefore, it can be used as the theory and technology support of flood risk analysis.
