| چکیده | ||
| این پژوهش به ارائۀ نوعی روش جامع کاربردی در ارزیابی عملکرد فنی سامانۀ بهره‌برداری اپراتور‌محور در توزیع آب سطحی تحت شرایط مختلف کمبود تأمین آب در یک شبکۀ آبیاری میپردازد. برای این منظور، از مدل شبیهساز انتگرالی‌ـ تأخیری برای شبیهسازی توزیع جریان در کانالهای اصلی و فرعی شبکۀ آبیاری نکوآباد اصفهان بهرهگرفته شد. شرایط مرزی مدل شبیهساز بر اساس تحلیل آمار تاریخی از سامانۀ تأمین آب سطحی در محل بند انحرافی و در قالب 7 سناریوی منتخب شامل شرایط نرمال تا شرایط کم‌آبی ملایم تا حاد انتخاب شد. ارزیابی فنی سامانه بهره‌برداری شامل: 1) تحلیل زمانی دبی تحویلی به آبگیرها و محاسبۀ میانگین روزانه کفایت توزیع آب در محل 13 آبگیر درجۀ 2 و 149 آبگیر فرعی و 2) تحلیل مکانی پراکندگی شاخص یادشده در سطح شبکه در قالب نقشههای پهنه‌بندی کفایت توزیع آب تحت هر سناریوی بهره‌برداری بود. نتایج از الگوی غالب و تکرار‌شوندۀ کاهش کفایت توزیع آب از محل منبع به سمت پاییندست در کانال اصلی و در هر 13 کانال درجۀ 2 بود. دامنۀ تغییرات میانگین روزانۀ شاخص کفایت توزیع آب سطحی به‌ترتیب در سناریوی نرمال تا سناریوهای کم‌آبی 10%>، 10-15%، 15-20%،20-30%، 30-40% و <40% برابر با 95-64%، 56-90%، 54-89%، 50-89%، 49-86%، 46-86% و 77-33% به دست آمد. همچنین نقشههای پهنه‌بندی مکانی کفایت توزیع آب حاکی از الگوی واضحی از ناکارآمدی سامانۀ بهره‌برداری در توزیع کافی آب سطحی تحت سناریوهای کم‌آبی ارائه کرده و مناطق آسیبپذیر شبکه را مشخص کرد. | ||

| The research conducted was aimed at developing a comprehensive method to evaluate the technical performance of an operator-centered Operation. The study was conducted under different water supply shortage conditions. The NekooAbad irrigation District was selected for simulation purposes using the Integral-Delay model to simulate flow distribution in the canals. The boundary conditions were based on historical statistics of surface water supply at the source. Seven scenarios were created, ranging from normal to severe water shortage. The technical assessment was based on two aspects: temporal analysis of the daily average water distribution adequacy in 13 main and 149 secondary off-takes. The second aspect included spatial analysis of the distribution of the mentioned index throughout the district. The study classified water distribution adequacy under each scenario. The results showed a pattern of reduced water distribution adequacy from the source to the downstream in all 13 secondary and the main canal. The daily average of the surface water distribution adequacy index ranged from over 10% in the normal scenario to less than 40% in the water scarcity scenarios. The percentage changes ranged from -95% to 64%, 90% to 56%, 89% to 54%, 89% to 50%, 86% to 49%, 86% to 46%, and 33% to 77%. The study also revealed a clear pattern of the operational system's inefficiency in the adequate distribution of surface water under water scarcity scenarios. Furthermore, it identified the vulnerable areas of the district through spatial regionalization maps of water distribution adequacy. | ||
