摘要/Abstract

摘要： 洪水风险图可以综合直观反映某一区域洪灾发生时的淹没特征信息、区域的地理特征信息和社会经济,其已成为洪水风险管理的重要科学依据。为加强南澧河区域的安全建设规划,利用MIKE软件建立了南澧河河道及两岸保护区的一维和二维耦合水动力学模型,采用海河流域“96·8”历史洪水资料进行了模型的验证。利用该模型模拟了南澧河发生100 a一遇的洪水演进过程。通过对比验证,此模型可以作为南澧河洪水风险分析的依据,为南澧河周边的安全建设提供重要依据。

Abstract: Flood risk map is a vital scientific basis for flood risk management as it reflects the flood features, geographic elements and socio-economic information in the submerged area comprehensively and directly. To strengthen the safety construction planning of Nanli river area, a hydrodynamic model coupling 1D and 2D models of the river channel and both banks of Nan liriver is established by using MIKE software. The model test result is verified by historical flood data in August of 1996 in the Haihe river basin. The coupled model is used to simulate the flood routine process for 100-year event flood. Results validate that the established model could be used as a basis for flood risk analysis of Nanli river, and provide reference for the safety construction around the Nanli river.

Key words: Nanli river, flood risk analysis, MIKE, 1D-2D coupling, hydrodynamic model
