Prioritization of Sub-Catchments for Operation of Watershed Management Projects Via Multi-Criteria Decision Making Techniques (Case Study: Asyabjofeth Watershed)

Few researches about prioritization of sub-watersheds of watersheds were conducted to watershed management operations in the world. Cause of existing of professional intervention in traditional method of watershed management office, this research was carried out to prioritization of sub-watersheds via multi-criteria decision making techniques (TOPSIS and VIKOR method in 12 different weighting conditions) in Asyabjofeth watershed. Problems was divided to 5 criteria as soil erosion and deposition, drought, flood, aridity, socio-economic problem. According to results, first scenario (equal weight of sub criteria) of TOPSIS and VIKOR methods and traditional method conducted same in recognition of two most and least critical sub catchments and differed together in recognition of sub watersheds with moderate critical.
