摘　　要：为克服没有实测数据校准SWMM(storm water management model)的难点,选用传统的径流系数法,从降雨径流总量以及降雨径流过程2方面来验证SWMM.结果表明,SWMM模拟的场次降雨径流总量以及年降雨径流总量与径流系数法估算的径流量的相对误差在可接受范围内,并且模拟的降雨径流过程与径流系数法推算的径流过程匹配结果也较好,说明SWMM能够较好地用于城市降雨径流总量以及过程的模拟,为后期进行降雨径流污染物总量及产生规律的研究提供了工作基础.SWMM（storm water management model） is now widely used for simulation of runoff of urban rainfall.Usually,SWMM is calibrated and verified with experimental data.It is difficult however,to observe the process of rainfall-runoff in some areas,so in order to avoid this difficulty,traditional runoff coefficient method was chosen to calibrate SWMM data from two aspects,total rainfall-runoff and runoff process.It was found that SWMM could be used to simulate total rainfall-runoff and the runoff process,and provide useful data for runoff pollutant loadings.
