چکیده

افزایش نیازهای آبی در مناطق توسعه یافته، چالش‌های زیادی را در تأمین نیازها ایجاد نموده است. فرودگاه نیز به‌عنوان یکی از مناطق حساس و استراتژیک حمل بار و مسافر، از این قاعده مستثنی نیست. با توجه به خطراتی که در نتیجه برداشت بی‌رویه از آبخوان‌ها به‌دلیل نشست سطح زمین در باند پروازی می‌تواند ایجاد شود، برنامه‌ریزی برای تدوین الگوی بهینه مصرف بر اساس برداشت پایدار، از اهمیت بالایی برخوردار است. در این تحقیق بر اساس آمار و اطلاعات مصرف و برداشت و طرح‌های آینده محدوده فرودگاه بین‌المللی امام خمینی (ره)، مدلی بر پایه برنامه‌ریزی چندهدفه تدوین شد. در این مدل با هدف حداقل نمودن میزان عدم تأمین نیاز و هزینه انتقال آب بخش‌های واقع در هر منطقه نیاز، مقدار بهینه تخصیص از منابع آبی پیشنهادی به‌صورت سیاست‌های ماهانه برداشت از منابع بهره‌برداری زیرزمینی و به‌صورت گرافیکی تهیه شد. نتایج نشان داد که برای برداشت مطمئن از چاه‌ها باید دستورالعمل‌های بهره‌برداری ارائه شده برای هر چاه به دقت اجرا شود. این امر منجر به افزایش اطمینان‌پذیری تأمین و کاهش هزینه‌های ناشی از آن می‌شود. این رویکرد، قابلیت تعمیم به افق‌های آینده برنامه‌ریزی را داشته و می‌تواند با توسعه تابع هدف و محدودیت‌های آن، برای هر منطقه‌ای به‌کار رود.

Developing a Model for Optimal Use of Groundwater Based on Multi-Objective Planning, Case Study: Imam Khomeini International Airport

چکیده [English]

The increasing demand for water in developed regions has led to numerous water supply challenges. Given their sensitivity and strategic importance as zones of cargo and passenger transfer, international airports are no exception to this general rule. The potential dangers to ground subsidence on the runway as a result of excessive groundwater withdrawal warrant plans aimed at developing models for optimal groundwater withdrawal as a measure of sustainable use of aquifers. In this study, consumption and withdrawal data are used and future development plans of the Imam Khomeini International Airport are considered to develop a model for groundwater use within the region based on multi-objective programming. Considering the objectives of maximizing water supply and minimizing costs of water transmission to demand zones, the model was used to develop an optimal water allocation system for the region containing monthly groundwater withdrawal policies and graphical distribution plans. The results show that the operation instructions thus developed for each well need to be carefully executed in order to ensure its safe exploitation. Strict adherence to the instructions is expected to enhance water supply reliability and to reduce the associated costs. This approach can be tailored and scaled up for future planning horizons and is also replicable in other areas by developing the relevant objective functions and constraints.
