摘　　要：准确模拟降雨-径流动态变化规律是河流面源污染精准治理的先决条件。在收集分析金川河子流域、交汇处、排口、导管、闸门、泵站及运营制度等相关数据的基础上,概化金川河水系,采用SWMM构建金川河河网水动力模型,并基于模型开发不同降雨特征(少量多次降雨、短期暴雨)条件下水系径流预警预测平台,展示金川河流域的流量、径流变化趋势,以实现流域降水模型的快速推演和预警预测功能。Accurately simulating the dynamic changes of rainfall-runoff is a prerequisite for precise management of non-point source pollution in rivers.Based on collecting and analyzing data about the sub-basins,confluences,outlets,conduits,sluices,pump stations and operation systems of Jinchuan River,this paper generalized the Jinchuan river system and used SWMM model to establish the hydraulic model of Jinchuan River system.Moreover,based on the model,a rainfall early warning and prediction platform is developed under different rainfall characteristics(frequent light rain and short-term heavy rain).It shows the flow and runoff trends of Jinchuan River Basin,so as to achieve fast simulation and early warning forecasting functions of basin rainfall model.
