Zayandehrud River, the largest river in the central plateau of Iran, has suffered water management crisis due to the continued drought and increased consumption in various sectors, including drinking, agricultural, and industrial sectors. To achieve logical compatibility, and taking into account the multiple economic and social goals, optimum reallocation of water resources of Zayandehrud according to the capacity of the existing resources is inevitable. In this article, the modification plan of Zayandehrud water allocation between seven irrigation networks is presented. To increase the productivity of the agricultural sector, some measures are presented in the form of intervention levels and applied in the allocation plans and the results are compared with each other and with the allocation in the current situation. These measures include changing the distribution of water between the networks under the current cultivation conditions, modifying the cultivation pattern, increasing the irrigation efficiency, and increasing the added value with the export of agricultural products. The results reveal that the current pattern of allocation between irrigation networks is not optimal in terms of economics and employment. Different levels of intervention in ideal conditions (combining all levels together) increase the value of water in the agricultural sector up to 30 times, among which export of the products abroad and modification of the cultivation pattern increase the value of agricultural water by 9 and 3.7 times, respectively.
