Operational management of agricultural water based on an economic perspective was investigated as a sustainable approach in water shortage periods. Accordingly, an automatic water distribution system was coupled with the Positive Mathematical Programming economic model for a sustainable agricultural water operation in the Roodasht irrigation network, Iran. Operational management was carried out based on the economic value of water in each irrigated unit. According to the results, the existing operating system was able to supply 71 and 22% of farmers’ water requirements under normal and water shortage conditions, respectively. However, employing the proposed automated operational-economic approach reduced water consumption by 14.3%, while maintaining the cultivation area by 11% and increasing farmers’ net profit to 840,000 USD under water scarcity. The economic operation can reduce water losses, implement economic strategies in those districts without water marketing mechanisms, and provide sustainable management of limited water resources in hyper-arid regions.

在缺水时期，作为一种可持续的方法，对基于经济角度的农业用水的运营管理进行了研究。因此，在伊朗Roodasht灌溉网络中，将自动配水系统与“正数学规划”经济模型相结合，以实现可持续农业用水运营。根据每个灌溉单位的水的经济价值进行运营管理。根据结果​​，在正常和缺水条件下，现有的操作系​​统分别能够满足农民的71％和22％的用水需求。但是，采用拟议的自动化运营-经济方法可将水资源消耗减少14.3％，同时将耕地面积保持11％，并在缺水的情况下将农民的净利润提高至84万美元。
