Limited documentation exists regarding parameterization of SWMM’s permeable pavement module and whether the output is realistic, particularly for long-term simulations. In this paper, we evaluated SWMM’s ability to replicate discharge and evaporation from three lined permeable pavement stalls. An assessment of parameter sensitivity identified the permeable pavement module’s input parameters with the highest relative sensitivity. Agreement between observations over a 1-year period and output from the calibrated model was inconsistent for 18 modelled rainfall events. While event volumes and shapes were matched relatively well for two concrete paver stalls for simple single-peak events, more complex multi-peak events showed poor agreement for all stalls. The porous asphalt stall was modelled least satisfactorily, due to its retention capacity that cannot be represented in the model. Based on the findings of this study, an evaporation coefficient (between 0.2 and 0.9), should be applied for long-term simulations of permeable pavement for best results.

关于SWMM的渗透性路面模块的参数设置以及输出是否真实（特别是对于长期模拟），文献很少。在本文中，我们评估了SWMM在三个衬砌的可渗透路面摊位上复制排放和蒸发的能力。对参数灵敏度的评估确定了渗透性路面模块的输入参数具有最高的相对灵敏度。对于18个降雨事件，在1年期间的观测值与校准模型的输出之间的一致性不一致。对于简单的单峰事件，两个混凝土摊铺机摊位的事件量和形状相对比较匹配，而对于更复杂的多峰事件，所有摊位的一致性都较差。多孔沥青摊位的建模效果欠佳，由于其保留能力无法在模型中表示。根据这项研究的结果，应将蒸发系数（0.2到0.9之间）用于渗透性路面的长期模拟，以获得最佳效果。
