Recent techniques should be investigated in detail to avoid present and future problems of urbanization like flood, drought and water pollution. Low Impact Development (LID) Best Management Practices (BMPs) such as bioretentions, green roofs, rain barrels, vegetative swales, and permeable pavements have been implemented to diminish the adverse effects of urbanization. In this study, a hydrological model for a Rainfall-Watershed-Bioretention (RWB) system is developed by using the Environmental Protection Agency Storm Water Management Model (EPA SWMM). RWB system is an experimental setup which consists of an artificial rainfall system, a drainage area and four bioretention columns with different soil mixtures. The hydrological modeling capability of SWMM for bioretentions is presented using the experimental data obtained from the experiments conducted in the RWB system under different rainfall events and for bioretentions with different designs. Finally, the modeling results of SWMM are compared with the results of the Hydrological Model of RWB (HM-RWB) system. Results show that EPA SWMM performs well in modeling bioretentions whereas the results of HM-RWB are in better agreement with the experimental data.
应详细研究近期技术，以避免当前和未来城市化带来的诸如洪水、干旱和水污染等问题。低影响开发（LID）最佳管理实践（BMPs），如生物滞留池、绿色屋顶、雨水桶、植被浅沟和透水路面，已被采用以减轻城市化的不利影响。在本研究中，利用美国环境保护局雨水管理模型（EPA SWMM）开发了降雨-流域-生物滞留（RWB）系统的水文模型。RWB系统是一个实验装置，由人工降雨系统、排水区域和四个装有不同土壤混合物的生物滞留柱组成。利用在不同降雨事件下RWB系统中进行的实验所获得的实验数据，以及针对不同设计的生物滞留池，展示了SWMM对生物滞留池的水文建模能力。最后，将SWMM的建模结果与RWB水文模型（HM-RWB）系统的结果进行了比较。结果表明，EPA SWMM在生物滞留池建模方面表现良好，而HM-RWB的结果与实验数据的一致性更好。
