This study presents a mechanism for managing the quantitative demand for water resources using the WSUD approach in the catchment area due to the high subsidence in southwest Tehran due to a groundwater decline. Due to the complexity of the physical and social environment in urban geography, the present dissertation has two general sections: social and physical-behavioral modeling. In the social sector, the emphasis is on identifying key stakeholders, studying their position and relationships in urban development, and explaining the importance of a WSUD approach as a conflict resolution approach. The statistical population in this section includes all key stakeholders in urban management and development. In this section, 13 institutions have been identified, and by classifying them as protection, development, and mediating institutions, their position, and importance in urban development have been studied. This section has obtained the interest power matrix using the Likert questionnaire and scale (5-1). According to the results of the stakeholder analysis, the strength and interest parameters of the Tehran Regional Water organization (4.02, 4.28) and Tehran Municipality (3.41 and 3.82) are higher than the others, considering their different desirability, indicating the potential conflict. Then, according to the above results, using social network analysis in the Gephi software environment, the type and level of inter-institutional relationships in groundwater management and comprehensive water resources (including groundwater, surface water, and wastewater) are estimated. The results of the social network analysis showed that in groundwater management in the cooperation network, the Tehran Regional Water and Tehran Municipality have the highest and lowest degrees (18 and 8). Tehran Regional Water and Tehran Municipality have the highest degree (5) in the conflict network, which indicates a high level of conflict between the two institutions. In water resources management, Tehran Regional Water have the highest degree of cooperation (20) and the lowest degree of conflict (2), and the municipal institution has the lowest degree of cooperation (11) and the highest degree of conflict (6) compared to other stakeholders. Social studies are essential in expressing the importance of a WSUD approach to resolving inter-institutional conflict. In other words, WSUD, considering the desirability of the development institution for urban geographical use and the desirability of the protection institution to protect the natural water cycle, can be considered in resolving the conflict between these two institutions. Then, to eva‎luate the efficiency of WSUD tools appropriate to the problem of the study area, physical-behavioral modeling of the study area was done. Tools based on WSUD in urban geography have been studied in the physical-behavioral modeling section. In this section, the physical part of the study area has been done using the water balance method, and the behavioral part has been done from the agent-based method. The results showed the average groundwater level in the desired period compared to the base year. If the current trend continues, the aquifer will decline in all three regions, significant in area 3 (about 63%). Also, in two conditions, feeding the aquifer with reclaimed wastewater and using WSUD tools can effectively control groundwater depletion.
