通过建立河流一维不恒定水流数学模型,模拟缺乏实测水位、流量资料,同时受洪潮影响的山溪性中小河流的设计洪水的途径,从而推求得河流设计洪水水面线的计算方法。
Through the establishment of a one-dimensional mathematical model of unsteady water flow in the river and simulating the design flood of the small and medium-sized rivers and streams lacking measured water level and flow data and being affected by the flood, a method for calculating the design flood waterline of the river is deduced.
