| چکیده | ||
| ارزیابی تغییر کمی منابع آب سطحی در مقیاس زمان و مکان در برخی از آبخیزهای استان اردبیل، امکان موازنه و تخصیص بهینهی منابع آب را در وضعیت فعلی و آینده فراهم خواهد آورد. مدیران منابع آب نیازمند دست‌رسی به اطلاعات اعتمادکردنی از میزان آب دست‌رس و مصرف‌های آن برای تصمیم‌گیری در تخصیص این منابع‌اند. هدف از این پژوهش برآورد مقدار آب مازاد جریان سطحی رودخانه در زیرحوضه‌های استان اردبیل در مقیاس ماهانه است. داده‌های آب‌دهی ثبت‌شده در 23 ایستگاه آب‌سنجی در سال‌های 1368 تا 1393 در 21 حوضه ارزیابی شد. شاخص کم‌بود آب (WSI) و شاخص کم‌بود آب با نگاه‌به جریان زیست‌محیطی (WSIef) نیز محاسبه شد. طبق نتایج، حجم آب مازاد در همه‌ی ایستگاه‌ها به‌استثنای چهار ایستگاه مشیران، بوران، دوست‌بیگلو و سامیان، در بیش‌تر ماه‌ها و فصل‌های مختلف و به‌خصوص ماه‌های گرم سال چندان زیاد نیست. اختلاف میان نتایج شاخص WSI و WSIef نشانگر این واقعیت است که در استان اردبیل برای تأمین نیازهای بخش‌های مختلف کشاورزی، خانگی، و صنعت نه‌تنها جریان و آب‌دهی طبیعی رودخانه مصرف می‌شود، بل‌که جریان زیست‌محیطی نیز از رودخانه برداشته می‌شود. با برداشتن جریان‌زیست‌محیطی و درنظرنگرفتن آن در نظام مدیریتی منابع آب، حیات زیست‌بوم‌های وابسته به جریان‌های سطحی در خطر خواهد بود. | ||

| چکیده [English] | ||
| Assessment of quantitative variationsof the surface water resources in the temporaland spatial scale in some watersheds the province of Ardabil will provide the possibility of balancing and optimal allocationof water resources in the current and future situations. Water resource managers need to have access to reliable information about the amount of available water and costs to decide on the allocation of this resource. The purpose of this study is to evaluate the temporal and spatial variations of excess volume in surface waters in some watersheds the provinceof Ardabil. The data collected at 23 hydrometry stations during the 1989–2014 periodin 21 watersheds were evaluated. The Water Stress Indicators (WSI and WSIef) were calculated. Excluding the Mashiran, Buran, Dostbeiglou and Samian stations, the remaining stations do not have too much excess water in most of the months and seasons, especially during the warm months. The difference between the results of the WSI and WSIef indexes indicate that in order to meet the needs of different sectors of agriculture, drinking and industry the province of Ardebil, not only the discharge of the rivers are consumed, but also the environmental flow is taken from the rivers. By exploiting the environmental flow,thus not considering it in thewater resources management system, the survival of surface-dependent ecosystems is at stake. | ||
