The aim of this study was to evaluate the relative resilience of the Samian watershed located in Ardabil province using five indicators including specific erosion and sediment, drought, flood potential, climate, and socio-economic in different weighting conditions. At the equal weighting, the average relative resilience index of Samian Watershed was 0.53, which indicates the average relative resilience. Considering the weight of each indicator at the same level in 27 different sub-watersheds of Samian, sub-watershed 8 located in the east with priority 1 had the highest relative resilience. Considering the equal weight and with emphasis on climate, flood potential and socio-economic indicators, sub-watershed 27 located in the central part of Samian Watershed was at the lowest level of relative resilience and was given priority 27 and sub-watershed 8 has been recognized as the most resilient sub-watershed. Sub-watershed 27 has been permanently in utilization due to the use of rainfed cultivation. Emphasizing erosion and sediment, and drought indicators, respectively sub-watersheds 25 and 23 located in the center of Samian Watershed were ranked in 27 priority.
