Wastewater treatment plants (WWTPs) are at high risk of coastal flooding due to the proximity of water bodies. Furthermore, power outages caused by extreme weather make their recovery process more challenging. In this paper a multi criterion decision-making (MCDM) method is utilized to involve different aspects of WWTPs’ flood resilience into the framework developed for distributing financial resources among them. The flood resilience improvement of plants is investigated for a wide range of interventions and related costs. On this basis, utility of the allocations is developed for each plant and a fixed budget is distributed among them in different ways. Due to the stochastic nature of floods, the uncertain resilience attributes of systems and the subjective views of experts and decision-makers, uncertainties are incorporated into this process. Accordingly, the uncertainty of each plant is targeted. The results show that: water-energy interdependence plays a significant role in assessing the flood resilience of WWTPs; using different ways of allocation leads to varying degrees of uncertainty in investment in each plant; and evidence theory is an effective way of integrating experts’ beliefs in the process of allocating resources. The proposed methodology can be implemented on similar cases in different geographic settings. doi: 10.2166/hydro.2020.145 om http://iwaponline.com/jh/article-pdf/22/4/768/715016/jh0220768.pdf 2021 Mohammad Karamouz (corresponding author) A.

考虑相互依存关系的污水基础设施抗洪能力的不确定性预算分配

由于靠近水体，污水处理厂 (WWTP) 面临着沿海洪水泛滥的高风险。此外，极端天气造成的停电使他们的恢复过程更具挑战性。在本文中，利用多准则决策（MCDM）方法将污水处理厂抗洪能力的不同方面纳入为在它们之间分配财政资源而开发的框架中。对植物的抗洪能力改进进行了广泛的干预和相关成本的调查。在此基础上，为每个工厂开发分配的效用，并以不同方式在它们之间分配固定预算。由于洪水的随机性、系统弹性属性的不确定性以及专家和决策者的主观看法，不确定性被纳入了这个过程。因此，每个工厂的不确定性都是有针对性的。结果表明：水能相互依存对评价污水处理厂的抗洪能力具有重要作用；使用不同的分配方式导致每个工厂的投资存在不同程度的不确定性；证据理论是在资源配置过程中整合专家信念的有效途径。建议的方法可以在不同地理环境中的类似案例中实施。doi: 10.2166/hydro.2020.145 om http://iwaponline.com/jh/article-pdf/22/4/768/715016/jh0220768.pdf 2021 Mohammad Karamouz (通讯作者) A.
