大红门地区属于北京市洪涝多发区，近年来，随着城市化进程加快，洪涝灾害进一步加剧.本研究基于SWMM模型构建了该区域一维管网、河网模型相耦合的城市雨洪模拟模型，并分别选用20000808、20030627、20010724号实测三场暴雨和洪水资料，对模型参数进行了率定和验证.结果表明：率定期流量相对误差分别为3.37%和-7.45%，洪峰流量相对误差分别为-7.65%和-9.84%，峰现时间相对误差分别为2 h 和0；检验期20010724号洪水流量相对误差为18.28%，洪峰流量相对误差为14.4%，峰现时间相对误差为0.研究结果表明，该模型能够较好的模拟北京大红门排水片区的雨洪过程，可为该区域的防洪决策提供技术支撑.

Flood and waterlogging are rather common in the Dahongmen area in Beij ing,which intensified after rapid urbanization.SWMM (Storm Water Management Model )was used to develop an urban storm simulation model.Three typical storms (occured on 20000808,20030627,and 20010724 respectively)were used for model calibration and validation.The relative errors of streamflow were found to be 3.37% and-7.45%;the relative errors of peak flow were -7.65% and -9.84%;the relative errors of peak time were 2 h and 0 h for two of the calibration storms.For a third validation storm on 20010724,relative error of streamflow was 18.28%;relative error of peak flow was 14.4%;relative error of peak time was 0.These data indicate that SWMM model simulates urban storms rather well and can provide technical support for the control of flood and waterlogging in the Dahongmen drainage area.
