S WMM模型在城市暴雨洪水模拟中的参数敏感性分析
Analyzing parameter sensitivity for the SWMM model in urban storm water simulation
摘要
Abstract
Storm Water Management Model (SWMM ) uses spatial parameters to analyze regional hydrological characteristics and urban storm water process.Since many uncertain parameters affect the model, it is necessary to analyze the sensitivity of model parameters.Three floods from 2000-2003 in Dahongmen drainage districtin in Beij ing was selected for model calibration and validation.Morris screening was applied for parameter sensitivity analysis.SWMM model was found to be suitable for flood simulation.The manning roughness coefficient for impervious area,the percentage of imperviousness areas and slope were found to be sensitive to both flood peak and relative error,the percentage of imperviousness areas and slope were sensitive to correlation coefficient.关键词
