Simulation of water allocation in Sefidroud irrigation and drainage network for sustainability of rice production

摘要

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.
