ABSTRACT

This study addresses the stormwater management challenges and opportunities in the recently growing city of Bojnord in the northeast of Iran assessing six Low Impact Development (LID) stormwater management alternatives using hydrological, social and economic criteria through a questionnaire survey and modeling effort. Hydrological and economic effects were assessed using the SWMM model and cost analysis, respectively. Different LID alternatives were evaluated using six different multi-criteria decision-making (MCDM) approaches including TOPSIS, VICOR, SAW, MEW, ELECTRE III, and NFM. Due to differences in the ranking results of the MCDM methods, three aggregation methods of Rank average, Borda, and Copeland were used to reach consistency in the ranking. Rain barrel installation has been assessed as the most preferred LID alternative and the pervious asphalt as the least preferred one. The evaluation and ranking of the alternatives with MCDM approaches facilitated the effective prioritization of sustainable LID alternatives according to various management objectives.

摘要

本研究解决了伊朗东北部最近发展壮大的 Bojnord 市的雨水管理挑战和机遇，通过问卷调查和建模工作，使用水文、社会和经济标准评估了六种低影响开发 (LID) 雨水管理替代方案。分别使用 SWMMH 模型和成本分析评估了水文和经济影响。使用六种不同的多标准决策 (MCDM) 方法评估不同的 LID 替代方案，包括 TOPSIS、VICOR、SAW、MEW、ELECTRE III 和 NFM。由于MCDM方法的排序结果存在差异，采用Rank average、Borda、Copeland三种聚合方法来达到排序的一致性。雨桶安装已被评估为最优选的 LID 替代方案，而透水沥青则是最不优选的方案。使用 MCDM 方法对替代方案进行评估和排名，有助于根据各种管理目标对可持续 LID 替代方案进行有效的优先排序。
