The increasing complexity and uncertainty associated with decision-making involved in projects, has led to a more comprehensive and systematic multi-criteria approach being undertaken
Multi-criteria decision-making (MCDM) methods have been used to prioritise structural flood control options for the effective management of flood risks. A recent study carried out by researchers from Iran and Poland has provided valuable insights to help assist policymakers and stakeholders in effectively allocating resources and implementing appropriate structural flood control measures. MCDM approaches are described as offering “a

systematic framework for evaluating and ranking various flood control measures based on multiple criteria”. This approach considers the complex and multidimensional nature of flood management, including both technical and non-technical aspects, such as cost-effectiveness, environmental impacts, social acceptability, and resilience. According to the authors Hamidifar et al in their work published in The Journal of Flood Risk Management, the increasing complexity and uncertainty associated with decision-making in the field of hydrology has given the application of MCDM methods more prominence.
The main aim of their study was to offer decision-
makers, flood control engineers, and researchers a thorough understanding of the strengths, limitations, and practical implications related to prioritising different structural flood control solutions. This was achieved by utilising a range of predefined criteria and employing four MCDM techniques.
Study area The study area encompassed approximately
15,563km2 of the Kohgiluyeh and Boyer-Ahmad
Province in southwestern Iran. With an average annual rainfall of 550mm and a moderate temperature range of 15 to 26o
C, the province is known for its
diverse topography. The main rivers of Maroun, Khersan, Zohre, Beshar, Nazmakan, and Marbor, also pose significant flood risks during heavy rainfall and snowmelt events. In the past, decision makers have put forth various development proposals for flood control, and several small and large dams have been built on the rivers in the province – the most notable being the Kowsar, ShahQasem, and Chamshir dams.
