基于暴雨径流管理模型(SWMM)的海绵城市低影响开发措施控制效果模拟
Simulation on the control effect of low impact development measures of sponge city based on storm water management model (SWMM)
摘要
Abstract
In order to solve the problems of water ecology,water security and water environment in the process of urbanization,sponge city,the new urban storm water management concept,was put forward based on the low impact development (LID).The Chicago rain type formula and Shenyang rainfall intensity formula were used to form Shenyang rainfall process line of different return periods.The water quantity and quality processes of the three scenarios,before urbanization,after urbanization and after setting LID measures,were simulated and analyzed by storm water management model (SWMM).The results showed that with the increase of rainfall return period,the reduced runoff volume of LID measures was gradually increased,and the runoff volume was close to that before urbanization.LID measures removed lots of TSS and COD,but their emissions were still higher than that before urbanization,while that of TN and TP were close to that before urbanization.With the increase of the rainfall intensity,the runoff velocity increased,but the removal of TSS,TP and COD by LID measures decreased gradually.关键词
