The performance of an irrigation water delivery canal located in northern Iran, which supplies water to 5,514 ha of paddy fields through ten secondary canals, was investigated. Throughout the rice growing season in the region, two performance measures, the measure of adequacy (P_A) and the measure of equity (P_E), were calculated for the system. It was observed that the canal, in its current physical and operational condition, is unable to distribute available water among all upstream and downstream users adequately. While 46.7 % of the total area is experiencing significant water scarcity, the amount of water received by 51.4 % of the area is approximately three times more than required. To improve the performance of the canal, structural and non-structural modifications were proposed and assessed using the SOBEK hydrodynamic model. The results showed that implementing the proposed modifications would decrease the measure of equity by 71.7 %, meaning that the overall performance of the canal could be reasonably improved.

对位于伊朗北部的灌溉水输送渠的性能进行了研究，该灌溉水渠通过十条辅助渠向5,514公顷的稻田供水。在该地区的水稻生长季节中，有两项绩效指标，即充足性指标（P _A）和公平指标（P _E）。），为系统进行了计算。据观察，在目前的物理和运行条件下，运河无法在所有上游和下游用户之间充分分配可用的水。虽然占总面积的46.7％严重缺水，但占总面积51.4％的用水量大约是所需水量的三倍。为了改善运河的性能，提出了结构和非结构性修改方案，并使用SOBEK流体动力学模型进行了评估。结果表明，实施拟议的修改将使公平率降低71.7％，这意味着运河的整体性能可以得到合理的改善。
