Comprehensive management is a new concept and a new approach in planning, development, management of water resources and vegetation with special emphasis on economic, social and environmental issues. The purpose of this research is to present the comprehensive management strategies of the Dubai Basin using the SWOT model and determine the implementation priority with QSPM. For this purpose, first the weaknesses, strengths, opportunities and threats of the studied basin were extracted using the brainstorming method and group decision-making for the Doabi watershed in Tehran province, and then the relative importance and final value of each factor in the matrix was determined and analyzed. In order to prioritize the strategies, the QSPM matrix was also used. The results of this study showed that the component of the presence of springs, aqueducts and rivers in the basin with a weight of 0.24 as the most important strength, two weak components of lack of water and humidity in the downstream areas of the basin and low rainfall in the outlet area of the basin with a weight score of 0.24 as The most important weak points, the component of grade 1, 2 and 3 asphalt and dirt roads with a weight of 0.16 have been identified as the most important opportunity and the component of flood and its resulting damages with a weight of 0.18 as the most important threat. The results also showed that the evaluation matrix of internal and external factors was 3.15 and 3.16, which indicated the dominance of strengths over weaknesses and opportunities over threats. In other words, the Doabi watershed is in an aggressive strategy. In order to manage opportunities and strengthen those, strategies were proposed and based on the QSPM matrix, management operations were placed as the first priority and biological operations were placed as the second executive priority.
