Best management practices (BMP) seek to mimic the pre-development hydrological behavior by increasing infiltration and reducing runoff. However, its use worldwide is still scarce. This work presented a methodology for prioritizing areas for the allocation of BMP to counteract the negative effects of urbanization. It was proposed the allocation of bioretention cells, rain gardens, permeable pavement, green roof, and native vegetation landscaping. The Storm Water Management Model (SWMM) was used to assess the efficiency of the practices used. The methodology for prioritizing areas identified places that most need intervention. This study showed that 93.7% of the studied catchment had a high and medium susceptibility to runoff generation. The methodology suggested that 54.2% of the catchment received some kind of BMP. The native vegetation landscaping was the most recommended practice. Despite the use of the BMP, some flooding points remained in the catchment, however, they decreased from 42 to 28. The runoff’s depth reduced from 85 to 23 mm while the infiltration increased from 12 to 38 mm. The methodology favored the upper areas of the catchment. It can be concluded that the allocation of the proposed practices showed good applicability. This work also allows local managers to take measures aiming the sustainability and water security and serves as a basis for future work and applications in other urban catchments.

结合城市景观的最佳管理实践分配方法

最佳管理实践(BMP)试图通过增加入渗和减少径流来模仿开发前的水文行为。但是,其在世界范围内的使用仍然很少。这项工作提出了一种方法,用于确定BMP分配区域的优先次序,以抵消城市化的负面影响。有人建议分配生物保留单元,雨水花园,可渗透的人行道,绿色屋顶和本地植被美化环境。雨水管理模型(SWMM)用于评估所用实践的效率。确定区域优先次序的方法确定了最需要干预的地方。这项研究表明,有93.7%的流域对径流产生具有高和中等的敏感性。该方法表明,有54.2%的流域接受了某种BMP。推荐使用原生植被美化环境。尽管使用了BMP,集水区仍保留了一些洪水点,但从42个减少到28个。径流深度从85毫米减少到23毫米,而入渗深度从12毫米增加到38毫米。方法学偏爱集水区的上游地区。可以得出结论,提议的做法的分配显示出良好的适用性。这项工作还允许地方管理人员采取旨在可持续性和水安全的措施,并为将来在其他城市集水区的工作和应用奠定基础。方法学偏爱集水区的上游地区。可以得出结论,提议的做法的分配显示出良好的适用性。这项工作还允许地方管理人员采取旨在可持续性和水安全的措施,并为将来在其他城市集水区的工作和应用奠定基础。方法学偏爱集水区的上游地区。可以得出结论,提议的做法的分配显示出良好的适用性。这项工作还允许地方管理人员采取旨在可持续性和水安全的措施,并为将来在其他城市集水区的工作和应用奠定基础。
