【摘要】 介绍了SWMM模型中低影响开发(LID)模块的模拟原理,通过案例介绍了场地LID雨水系统规划过程,并运用SWMM模型对传统管线设计进行了校核,对LID场地径流的控制效果进行了评价。对设计场降雨事件及连续降雨事件的模拟表明,场地LID雨水系统规划可实现峰值流量及年径流外排率恢复到开发前的状态,LID设施对污染物削减效果显著。更多还原

【Abstract】 The simulation principle of LID module in SWMM model was presented.The site LID stormwater planning process was introduced through a case study.The design of traditional pipeline was checked by SWMM model,and the LID stormwater control effect was evaluated.The simulation of design rainfall events and continuous rainfall events indicated that the site LID stormwater system plan could achieve the peak flow and annual runoff discharge rate back to predevelopment levels.The reduction effect of pollutants by LID facilities was remarkable.更多还原
