基于SWMM的管网变化对城市水文特征的影响分析
Analysis of Influence of Pipe Networks Changes on Urban Hydrological Characteristics Based on SWMM
摘要
Abstract
Changes of pipe networks have great influence on runoff, infiltration and peak discharge. In this paper, the study area is first divided into several natural watersheds by ArcGIS's hydrological analysis module. Considering the restraint effects of roads and huge buildings, the natural watersheds are then divided into more subcatchments. After calibrating SWMM's parameters, two SWMM projects are established based on two different pipe networks, which adopt 24-h rainfall process with frequency of 30％ in Nanjing as rainfall input data. The results show that the infiltration decreases but the runoff and peak discharge increase in the affected areas. And the flood peak occurs earlier.关键词
