With the growing population and people’s increasing livelihoods, the need for agricultural products is increasing day by day, which in turn implies an increase in the water requirement in the agriculture sector. However, in countries such as Iran, the main problem in the agriculture sector is mismanagement, not lack of water resources as popularly claimed. The purpose of this study is to investigate the performance of the Sefidroud irrigation and drainage network and internal water resources of Guilan province in order to optimize the allocation of water resources with integrated management. The WEAP software was used for this purpose. Data were extracted from the Guilan Regional Water Authority and network reports and were added to the software. Different feasible management scenarios were evaluated. According to the results, the downstream environmental need of the Sefidroud irrigation network has always been met even in the worst conditions, but the Sefidroud irrigation network alone cannot meet the irrigation requirement of the region.

随着人口的增长和人们生活水平的提高，对农产品的需求日益增加，这反过来又意味着农业部门对水的需求增加。但是，在伊朗等国家，农业部门的主要问题是管理不善，而不是普遍声称的水资源短缺。这项研究的目的是调查桂兰省Sefidroud灌溉排水网络和内部水资源的性能，以便通过综合管理优化水资源的分配。WEAP软件用于此目的。数据是从桂兰地区水务局和网络报告中提取的，并已添加到软件中。评价了不同的可行管理方案。根据结果​​，
