“…In scale of catchment, given the inherent complexity of formulating flood risk management strategies and its high uncertainty due to some reasons such as large input data and long processing time, it is necessity to select sub-watershedsas a small-scale hydrological unit to prioritize them based on their flood potential (Aher et al, 2014;Anees et al, 2019;Shivhare et al, 2018). In this context, there are variety of approaches available to analysis and prioritize sub-watersheds using Multi Criteria Decision Analysis (MCDA) (Akay and Koçyiğit, 2020;Chitsaz and Banihabib, 2015;Ghaleno et al, 2020;Sepehri et al, 2019c), Soil and Water Assessment Tool (SWAT) (Mishra et al, 2007;Talebi et al, 2019a), artificial neural network (ANN) (Dehghanian et al, 2020), Storm Water Management Model (SWMM) (Babaei et al, 2018), support vector machine (SVM) (Fan et al, 2018;Tehrany et al, 2014) and The Hydrologic Modeling System (HEC-HMS) (Malekinezhad et al, 2017;Talebi et al, 2019b). Among aforementioned methods, MCDA has been taking into account due to its capability to handle nonlinear and complex problems and its usability to prioritize ungauged watershed.…”
