基于SWMM模拟的城市内河区域雨水径流和水质分析
SWMM simulationbased analysis on rainfall runoff and water quality within urban inland river area
摘要
Abstract
Based on SWMM (Storm Water Management Model) , the storm runoff and water quality in the typical area ( around clean water lake) of urban inland river are simulated herein; in which the relationship between storm runoff and water quality as a function of time is examined under the conditions of various return periods and permeable areas. The result shows that the permeability of ground surface is to be decreased, while the total runoff and its peak value are to be increased with the gradual decrease of the increment amplitude along with the increases of both the return period and the permeable area. Moreover, along with the increasing of both the return period and permeable area, the concentration of pollutant presents the trend that it gradually increases in the fore-period, peaks up in the mid-period and then gradually decreases in the late-period with more and more obvious flushing effect of pollutant. For the area with short return period and quick urbanization process, the permeability of ground surface is to be decreased along with the rise of the peak value and total runoff, therefore, the risk of flood and water logging is to be increased as well.关键词
