چکیده مقاله :

چکیده زمینه و هدف: امروزه آب به عنوان یکی از عوامل بهبود و رشد اقتصادی جوامع به شمار می آید تحقیق حاضر به منظور مدل سازی تعدادی از متغیرهای کیفی آب با دبی در دو زیرحوضه خلیفه ترخان و چهل گزی سد قشلاق سنندج، به تفکیک ماه های سرد و گرم سال و مقایسه آن با عدم تفکیک ماه های سرد و گرم سال در بازه زمانی 26 سال است. روش بررسی: در این پژوهش، پس از بررسی و صحت داده های دبی، هدایت الکتریکی، مواد محلول، کلر، کلسیم، سدیم، منیزیم، اسیدیته و نسبت جذب سدیم دو ایستگاه مورد مطالعه، سعی شد که روابط رگرسیونی مناسبی بین پارامتر دبی و پارامترهای کیفی آب ارایه شود. یافته ها: نتایج نشان داد که در زیرحوضه چهل گزی برای ماه های سرد، بین دبی با هدایت الکتریکی، املاح محلول، کلر و سدیم، رابطه خطی و هم چنین برای بیان ارتباط بین دبی با کلسیم رابطه نمایی مناسب تر بود. در ماه های گرم این زیر حوضه رابطه خطی ارتباط مناسب تری بین دبی با املاح محلول، هدایت الکتریکی، منیزیم، کلسیم، سدیم و نسبت جذب سدیم، ارایه نمود. هم چنین در زیر حوضه خلیفه ترخان درماه های سرد سال برای بیان ارتباط بین دبی با املاح محلول، هدایت الکتریکی، کلر، سدیم، رابطه خطی و برای بیان ارتباط بین دبی با کلسیم، رابطه نمایی مناسب تر بود. در این زیرحوضه برای ماه های گرم، ارتباط بین دبی با املاح محلول، هدایت الکتریکی، کلر، سدیم و نسبت جذب سدیم، رابطه خطی مناسب تر بود. مقایسه تفکیک ماه های سرد و گرم با شرایط عدم تفکیک نشان داد که در صورت عدم تفکیک ماه های سرد و گرم، برآورد کلر و منیزیم (در زیرحوضه چهل گزی) و برآورد کلسیم (در زیرحوضه خلیفه ترخان) امکان پذیر نمی باشد. بحث و نتیجه گیری: حال می توان با استفاده از این روابط و توجه به تغییرات فصلی کیفیت آب های سطحی، بدون انجام اقدامات آزمایشگاهی و تنها با داشتن مقدار دبی و در نظرگرفتن صرفه جویی اقتصادی به مدل سازی کیفیت آب، استخراج و بازیابی داده های کیفی آب اقدام نمود.

چکیده انگلیسی:

Background and Objective: Nowadays, water is considered as one of the factors for improvement and economic growth of societies. The hot and cold seasons of the year and its comparison with the non-segregation of the hot and cold seasons are 26 years. Method: In this study, after studying the accuracy of discharge data, electrical conductivity, soluble matter, chlorine, calcium, sodium, magnesium, acidity and sodium uptake ratio of the two stations, it was tried to find appropriate regression relationships between discharge parameter and qualitative parameters. Provide water. Findings: The results showed that the Chehelgazi sub-watershed in cold months, the liner relationship between discharge with electrical conductivity, dissolved solids, chloride and sodium and also the exponential relationship was suitable between discharging with calcium. In warm months for this sub-watershed, the linear relationship presented the suitable relationship between discharge with dissolved solids, electrical conductivity, magnesium, calcium, sodium and the sodium adsorption. Also, the linear relationship was suitable between discharge with dissolved solids, electrical conductivity, chloride and sodium whereas the exponential relationship was better between the discharging with calcium in Khalifehtarkhan sub-watershed. In this sub-watershed, for warm months, the linear relationship was suitable for the relationship between discharge with dissolved solids, electrical conductivity, chloride, sodium and sodium adsorption. The separation comparison of cold and warm months with non-separation showed that non-separation of cold and warm months is not possible the chloride and magnesium estimation (in Chehelgazi sub-watershed) and calcium estimation (in Khalifetarkhan sub-watershed). Discussion and Conclusion: using obtained relationships and seasonal changes of surface waters quality, with discharge rate can create modeling water quality, extraction and recovery of water quality data.
