| چکیده | ||
| آبهای زیرزمینی مهمترین منبع تأمین آب در بسیاری از نواحی ساحلی جهان هستند. با توجه به برداشت بیرویه از آبخوانها و هجوم آب شور، باید در آبخوانهای ساحلی مدیریت صحیح اعمال شود. در این مطالعه، آسیبپذیری آبخوان ساحلی قره‌سو-گرگان‌رود برای شناسایی نواحی آسیبپذیر با استفاده از روش SINTACS و GALDIT بررسی شده است. نقشههای آسیبپذیری این دو مدل در محیط نرم‌افزار GIS تولید، طبقهبندی و تلفیق شدند. بهمنظور دست‌یابی به مدل بهینه، ضریب همبستگی بین شاخصهای آسیبپذیری و غلظت TDS محاسبه شد. نتایج به‌دست‌آمده نشان داد مدل GALDIT ضریب همبستگی بیشتری نسبت به مدل SINTACS برای تهیۀ نقشۀ آسیبپذیری در منطقۀ مطالعه‌شده دارد. علاوه بر این، برای اصلاح مدل GALDIT از روش تحلیل حساسیت تکپارامتری استفاده شد. نتایج به‌دست‌آمده از این تحلیل نشان داد مؤثرترین پارامترها در ارزیابی آسیبپذیری آبخوان منطقۀ مد نظر، هدایت هیدرولیکی و ارتفاع سطح آب زیرزمینی بالاتر از سطح دریا هستند. | ||

| چکیده [English] | ||
| Groundwater is the most important source of water in coastal areas. Recently, due to overexploitation of the aquifer and seawater intrusion, a correct management in coastal aquifers must be applied. In this study, GALDIT and SINTACS models are used with geographic information system (GIS), in order to identify Gharesou-Gorganroud vulnerability areas. To generate, classify, weight and overlay vulnerability maps according to these two models, GIS environment is used. Geographic information system (GIS) is a useful tool to identify and assess vulnerability areas. The Pearson correlation coefficients is used to achieve an optimal model. To compare correlation results of GALDIT model and SINTACS model, GALDIT model has a higher correlation with TDS concentrations. In addition, Single parameter sensitivity analysis used to modify the GALDIT model to observe effect of each parameter on the GALDIT result model. In the study area, the result illustrated that the effective parameters in aquifer vulnerability assessment were hydraulic conductivity, depth of groundwater level, distance from the shore, type of aquifer, thickness of aquifer and impact status of existing saltwater intrusion, respectively. | ||
