Nowadays, due to the increasing growth of urbanization and the increasing need for water in urban communities, Water supply management in different parts of urban water consumption is one of the problems that made human life in serious crisis. Iran faces severe water supply crises due to being in an arid and semi-arid climate. Some cities like Isfahan have a worse situation from other cities in the north and south of Iran. Isfahan is one of the most important cultural, industrial and tourist cities. Migration from cities and villages adjacent to Isfahan, in addition to the net population growth rate of this city, has caused concern for the water supply needed in various urban areas of this area. Therefore, water resources management is very important in order to balance the water demand in different parts of urban water and the water resources in this area. One of the authorities' priorities is to provide the water for agriculture, industry, landscape and utilities needed to increase the welfare of local residents. Limited water resources to supply the water required for Isfahan created a serious crisis for water supply in different parts of the city. This study investigated ways of coping with dehydration in different parts of Isfahan. The effect of different policies on the resilience and sustainability of the Isfahan water resources system has been studied. The policies implemented in this model are evaluated in the context of two continuation hydrology, business as usual (B.a.U) and drought scenarios (D.S) and are compared by water resource indices. The results of these contexts show that the total water requirement of the city increased by 4.4% over the last 31 years (1400-1430). However, due to the capacity of the water supply system in Isfahan, it will decrease by 24% during this period. According to the complexity of Isfahan's water resources, applying a single approach and focusing on one sector can not only create better conditions for that sector but also create more problems for other sectors in the needed water supply. Therefore, changing the unit management approach to integrated and holistic management is one of the most fundamental and important solutions available to address the water supply problem in different sectors. To this end, an integrated urban water system management model based on systems dynamics theory has been developed. Also, the results of applying integrated management policy packages showed that the implementation of these scenarios had the greatest impact on the resiliency index of the Isfahan urban water system. Implementation of demand management strategies is of the utmost importance for balancing socio-economic development and water supply capacity. These packages increase the effectiveness of policy packages over the simulated period by reducing the amount of water required by different sectors. The results of this study show that water resources policymakers in Isfahan should focus on management and reduction of water requirement in landscape and agricultural sectors due to changes in the cropping pattern and use of drought-tolerant cultivars and reduction or removal of plants. Highly concentrated, as low as possible to reduce vulnerability to low rainfall.
