Feasibility of a Permeable Pavement Option in SWMM for Long-term Continuous Modeling
With increasing concern for the natural environment, current practices in stormwater management planning have moved away from traditional applications such as detention as a means of quantity control, towards techniques that combine both quantity and quality control. These techniques lower stormwater runoff volumes, recharge groundwater and mitigate the transportation of contaminants. One such type of management practice is installation of permeable pavement. The purpose of this study was to examine the feasibility of code for the Storm Water Management Model (SWMM) to allow planners and designers to simulate the responses of permeable pavements in long-term modeling applications. The infiltration capacity of the porous pavement was determined from past studies, and takes into account degradation over time and regeneration by mechanical means.
