چکیده

علم جریان زیست‏محیطی، ابزاری رایج برای ارزیابی پیامدهای تغییر رژیم‏های جریان بر اکوسیستم‏های آبی و تأمین حداقل جریان در حفاظت از گونه‏های آبزی است. هدف از پژوهش حاضر، فراهم‌کردن ملزومات برای مهیاشدن ابزار ارزیابی و طراحی پروژه‏های احیا و باززنده‏سازی زیستگاه رودخانة زرین‏گل با استفاده از شاخص‏های اکوهیدرولیکی، هیدرومورفولوژیکی مبتنی بر شبیه‏سازی مطلوبیت زیستگاه است. به این منظور بر پایة چارچوب تحقیق، پس از مطالعات میدانی و توسعة مدل مطلوبیت زیستگاه برای گونة هدف، شبیه‏سازی هیدرودینامیکی جریان صورت گرفت و در نهایت رژیم جریانات اکولوژیک استخراج شد. نتایج نشان داد مدل River2D با برقراری ارتباط بین خصوصیات جریان مورد نیاز گونة سیاه‏ماهی C.Capoeta gracilis و استفاده از روابط هیدرولیکی و هیدرولوژیکی، بیشترین و کمترین رژیم جریان مورد نیاز برای حفظ اکوسیستم رودخانة زرین‏گل را با توجه به نیازهای اکولوژیکی در ماه‏های فروردین و مهر به‌ترتیب معادل 09/5 و 89/0 مترمکعب بر ثانیه، با میانگین 79/1 مترمکعب بر ثانیه (معادل 84 درصد جریان طبیعی رودخانه) برآورد می‏‌کند. طبق نتایج تحقیق‌ حاضر، در مطالعات زیست‏محیطی منابع آب و مهندسی رودخانه، مدل دوبعدی هیدرودینامیکی River2D، قادر به شبیه‏سازی جریان، مدل‏سازی مطلوبیت زیستگاه گونة هدف و پیش‏بینی دینامیک زیستگاه برای محافظت از زیستگاه مناسب ماهی در اکوسیستم‏های رودخانه‏ای است. محاسبة جریان زیست‏محیطی می‏تواند تخمین مناسبی برای ارزیابی پاسخ اکولوژیکی رودخانه به تغییرات مورفولوژیکی ایجادشده بر اثر فرایندهای هیدرولوژیکی و هیدرولیکی باشد.

چکیده [English]

Environmental flow science is a current tool for assessing the outcome of changing the flow regime of aquatic ecosystems and providing a minimum flow of protection aquatic species. The purpose of this research is to provide the essentials in preparing the tools for the assessment and design of restoration and regeneration projects for Zarrin-Gol river habitats using ecohydraulic and hydromorphological indices based on the habitat suitability simulation. In this regard based on the research framework, after the field studies and the development of the habitat suitability model for the target species, the hydrodynamic simulation of the flow was carried out and eventually the ecological flow regime was extracted. The results showed that River2D model by connecting the flow requirement characteristics of C.Capoeta gracilis and using hydraulic and hydrological relations, would have the maximum and minimum flow regime required to maintain the Zarrin-Gol river ecosystem according to ecological needs in the months of April and October is estimated to order equivalent to 5.09 and 0.89 m3/s, with average 1.79  m3/s (equivalent 84 percent of natural stream of the river). Based on the results of this study, in environmental studies of water resources and river engineering, the two-dimensional hydrodynamic River2D model is able to simulate flow, modeling habitat suitability of target species and predict the dynamics of habitats to protect the proper habitat of fish in river ecosystems. The calculation of the environmental flow can be an appropriate estimate for the ecological response of the river to the morphological changes caused by hydrological and hydrological processes.
