River basins, especially in arid and semi-arid areas such as Iran and neighboring lands, have always been the center of human settlement and civilization. The increase in population and the pressure on water and soil resources in recent times, along with the development and progress in water supply technology and agricultural practices, have caused the importance of these limited resources in our country to be noticed more than before. Therefore, the management of water and soil resources and protective measures in new ways have gained more importance and necessity. This article has been prepared with the aim of introducing a part of the Sepidroud watershed management function and evaluating its social, economic and environmental consequences. In the conducted research, the socio-economic and environmental effects of this plan have been evaluated with a qualitative method. The main variables were social variables including migration, employment and local participation in the project; Economic variables including flood control, land reclamation, production rate and land price increase; and environmental variables, including the underground water level and limiting the river bed by turning it into agricultural land. With the statistical analysis of the data, the correlation between the variables was determined based on their value and importance, and the percentage of positive and negative effects of the project on each of the factors was obtained. The results of this research show that the Zanjanrud organizing plan has been very successful in controlling floods and increasing the cultivated area, and as a result, the amount of production and income of farmers has also increased. 92% of the respondents believed that this plan had significant economic effects for farmers.
