In this research, the effect of In-Line storagestrategy on operation and management of an automatic main irrigation canal is assessed as anapproachable method for improving the main irrigation canal performance in rehabilitation andmodernization projects. A Proportional-Integral (PI) local upstream controller is designed for Dezmain irrigation canal to assess the capability of the proposed strategy. The controller was tested for anextreme and sudden increasing–decreasing water off-taking scenario on two different operationconditions. The first one refers to the normal operation and the latter refers to operation of the maincanal with in-line storage in the three canal reaches of the case under study. Controller performancewas evaluated with ASCE indices includes: MAE; IAE; and StE, for irrigation schedule time period(6 days). Results indicate that using in-line storage strategy leads operational performanceimprovement. The maximum MAE index improvement happens in the first canal reach withimproving values from 2.1 to 0.32. For the IAE and StE indices, maximum improvements areobtained from 1.3 to 0.5; and from 0.71 to 0.14 respectively. The satisfactory results is obtained forthe irrigation schedule with drastic changes, so using in-line reservoirs lead to the better results for thenormal irrigation schedule.}, keywords = {}, title_fa = {استفاده از ذخیره درون مسیری در سامانه های کنترل خودکار به منظور بهبود فرایند بهره برداری در کانال اصلی آبیاری (مطالعه موردی کانال اصلی آبیاری شبکه دز)}, abstract_fa = {}, keywords_fa = {}, url = {https://jhyd.iha.ir/article_85345.html}, eprint = {https://jhyd.iha.ir/article_85345_fbda7b9f5807844d4730e4aebc4a064a.pdf} }
