基于暴雨管理模型(SWMM)的水生态小区低影响开发(LID)技术效果模拟及评估
Simulation and Assessment of LID Technological Benefit for Water Ecological Community Based on SWMM Model
摘要
Abstract
The aim of the thesis was to quantify the control effect of LID and build a model by LID for water ecological community through SWMM which was based on the principle of runoff generation from excess rain,the method of nonlinear flow concentration,and the calculation method of pipelines transport by de Saint-Venant system of equations.To this end,the author performed simulation and evaluation of the five schemes,namely the initial state,the independent layout of green roof,permeable pavement,sunken greenbelt respectively,and the integration of three LID measures,about the control effect toward water quantity and water quality in various recurrence periods of rainstorm,providing a case study of a certain area.The research indicated that the four projects of LID played a significant role in holding up and cutting down the rainfall runoff and peak flow.From the most effective to the least respectively were the combination of LID measures,permeable pavement,sunken greenbelt,green roof,which sequence also applied to the control of total amount of pollutant discharge in water quality.关键词
