Abstract

The efficiency of drainage systems in urban centers and especially in their peripheral regions has deserved more and more special attention since their interrelationship with social and environmental aspects is associated with the performance of drainage infrastructures. Integrated urban water management is a major factor in the effectiveness of an urban drainage system. In large cities, negative effects caused by the disorderly urbanization process, especially those related to rainwater runoff, are increasingly present. An evaluation model of urban drainage systems was generated using System Fragility Indicators (IFS) and their ranking via Analytic Hierarchy Process (AHP), in the Jaracati River basin, Maranhão State, Brazil. Indicators were measured through the evaluation of the system and the experience of specialists in drainage systems. The results obtained allowed for the consolidation of a model to support planning and decision-making in the assessment processes of measures to mitigate socio-environmental impacts involved in the urban drainage of a watershed, with performance indicators capable of guaranteeing the support of a model being verified measurement of performance parameters of urban drainage systems.

城市排水系统性能评价:巴西Jaracati流域的层次分析法
城市中心及其周边地区排水系统的效率值得越来越多的特别关注,因为它们与社会和环境方面的相互关系与排水基础设施的性能有关。综合城市水管理是影响城市排水系统有效性的一个主要因素。在大城市中,无序城市化进程所带来的负面影响,特别是与雨水径流相关的负面影响日益显现。利用系统脆弱性指标(IFS)和层次分析法(AHP)对巴西马拉南州贾拉卡蒂河流域的城市排水系统进行排序,建立了城市排水系统评价模型。指标是通过评价系统和排水系统专家的经验来衡量的。所获得的结果允许巩固一个模型,以支持在减轻流域城市排水所涉及的社会环境影响的措施的评估过程中的规划和决策,其绩效指标能够保证对模型的支持,并对城市排水系统的绩效参数进行测量。
