摘要
本文将水力学方法与水文学方法相结合,在用圣维南方程描述城市雨水地面径流过程的基础上引入全面汇流和部分汇流的概念,用线性叠加原理将均匀净雨强度下的坡面流理论应用于非均匀净雨强度下城市小区域地面径流模拟,从而建立了平原城市区域雨水地面径流过程模拟模型,并在进行流量过程线性叠加时采用3种净雨分割方式检验模型的模拟成果。最后将模拟结果与雨水管理模型SWMM进行对比,证明本文模型是较为合理和可行的,且具有一定的模拟精度和应用潜力。
The approach based on hydraulics is combined with the hydrologic method to simulate the runoff in small districts of a city. The San-Venant equation is applied to describe the flow of runoff and the theory for calculating the overland flow under the condition of even rain intensity is expanded to calculate the runoff in small districts under uneven rain intensity condition by using the principle of linear superimposition. The corresponding model is established. The calculated runoff of a small district in the Hangzhou City is in good agreement with the simulation result by using sewage water management model （SWMM）. It demonstrates that the proposed model is feasible.
