摘要
为探究重点集镇山洪演进规律,以小安溪流域为研究对象,结合实地勘测,利用GIS水文分析和MIKE11一维水动力模型模拟了重现期分别为5,10,20,50,100 a方案下小安溪流域洪水演进过程,得出了不同重现期下洪水沿程水面线动态模拟结果以及重点集镇断面的设计水位和典型断面堤岸的防洪能力。研究结果表明:模型对于小安溪流域洪水演进过程整体模拟结果可信,模拟结果可为小安溪流域内重点集镇的防洪评价以及预警提供一定的理论参考和支撑。
In order to explore the evolution laws of flash flood in key urban towns,the Xiao'anxi River is selected as the research object.Combined with field surveys,GIS hydrological analysis and MIKEll,an one-dimensional hydrodynamic model is used to study the flood routing processes of the Xiao'anxi River with return periods of 5,10,20,50,and 100 years.The dynamic simulation results of flood water surface profiles with different return periods,the design water levels of cross-sections at the key urban town,and the flood control capacity of typical cross-sections along the Xiao'anxi River are presented.The results indicate that the overall simulation results of the model for the flood routing process in the Xiao'anxi River are reliable,which can provide certain references and support for flood control evaluation and early warning of key urban towns in the Xiao'anxi River Basin.
