چکیده

آب‌های زیرزمینی در مناطق ساحلی، یکی از منابع اصلی آب شیرین محسوب می‌شوند به‌طوری که حفاظت این منابع از خطر پیشروی آب شور بر اساس یک الگوی مدیریتی بهینه، یک اولویت است. برای این منظور، می‌توان از مدل‌های تصمیم‌گیری برای تعیین راهبردهای مدیریتی بهینه استفاده نمود. آثار تغییرات محیطی بر روی منابع آب زیرزمینی در این مطالعه مورد بررسی قرار ‌گرفت. به‌منظور تحقق این هدف، مدل تلفیقی شبیه‌سازی-بهینه‌سازی منابع آب زیرزمینی جزیره کیش با بهره‌گیری از مدل عددی سوترا و روش بهینه‌سازی فراکاوشی جامعه مورچه‌ها مورد استفاده قرار گرفت. نتایج بررسی سناریوهای مختلف فرضی تغییرات محیطی نشان داد که اثر تغییرات خط ساحلی ناشی از افزایش سطح آب دریا به‌خصوص در مناطق پست، عامل مهم تأثیرگذار بر لنز آب شیرین است و تغییرات نرخ تغذیه نیز از عوامل بسیار مهم و مؤثر بر سیستم آب زیرزمینی تلقی می‌شود. همچنین لحاظ نمودن آثار تغییرات محیطی در مدیریت بهینه آبخوان جزیره کیش، منجر به کاهش بیش از 20 درصدی مقدار مجاز برداشت شده است که نشان دهنده حساسیت بالای مدیریت منابع آب زیرزمینی جزایر کوچک به این تغییرات است.

چکیده [English]

Groundwater in coastal areas is an essential source of freshwater that warrants protection from seawater intrusion as a priority based on an optimal management plan. Proper optimal management strategies can be developed using a variety of decision-making models. The present study aims to investigate the impacts of environmental changes on groundwater resources. For this purpose, a combined simulation-optimization model is employed that incorporates the SUTRA numerical model and the evolutionaty method of ant colony optimization. The fresh groundwater lens in Kish Island is used as a case study and different scenarios are considered for the likely enviromental changes. Results indicate that while variations in recharge rate form an important factor in the fresh groundwater lens, land-surface inundation due to rises in seawater level, especially in low-lying lands, is the major factor affecting the lens. Furthermore, impacts of environmental changes when effected into the Kish Island aquifer optimization management plan have led to a reduction of more than 20% in the allowable water extraction, indicating the high sensitivity of groundwater resources management plans in small islands to such variations.
