چکیده

در این مطالعه پارامترهای اکسیژن محلول، اکسیژنخواهی بیوشیمیایی و شیمیایی رودخانه عباس‌آباد همدان با استفاده از مدل QUAL2KW در فصل‌های بهار (تر) و تابستان (خشک) بررسی گردید. پس از آنالیز حساسیت مدل، داده‌های اردیبهشت، خرداد و مردادماه سال‌های 1390 و 1391 برای واسنجی و داده‌های مشابه 1394 برای صحت­سنجی استفاده گردید. دقت مدل از طریق محاسبه شاخص‌های آماری ضریب تعیین، خطای استاندارد و ریشه میانگین مربعات خطای نرمال بررسی شد. خطای استاندارد اکسیژن محلول، اکسیژنخواهی بیوشیمیایی و شیمیایی در مرحله واسنجی، به‌ترتیب در محدوده 038/0 تا 092/0، 058/0 تا 180/0 و 075/0 تا 156/0، در مرحله صحت‌سنجی به‌ترتیب در محدوده 007/0 تا 040/0، 225/0 تا 385/0، 166/0 تا 216/0 محاسبه شد. نتایج نشان داد روند تغییرات اکسیژن محلول در فصول تر و خشک تقریباً یکنواخت و خطی بوده که ناشی از شیب زیاد و هوادهی بالای رودخانه است. همچنین تغییرات اکسیژنخواهی بیوشیمیایی و شیمیایی نسبتاً مشابه و دارای روند افزایشی است.

چکیده [English]

In general, the entry of sewage into rivers and the decomposition into river water has led to a reduction in water quality and, in particular, a decrease in DO concentration (Sarda and Sadgir 2015). To have the optimal water quality characteristic, river reception capacity should remain within acceptable limits along the river. Using management tools, including water quality simulation models, can be very beneficial in this context. QUAL2KW is one of the best tools to simulate water quality due to its flexibility, ease of use, and availability. Studies with the QUAL2KW model for simulating water quality in rivers and basins using parameters BOD (Fang et al. 2008), Nitrogen, Phosphorus, and COD (Grabiç et al., 2011) have been carried out. This study aims to provide a model for simulating water quality parameters in rivers with steep slopes and short paths. Therefore, the analysis of BOD, DO, and COD qualitative parameters and awareness of the Abbas-Abad River's location and time trends (seasonal) in Hamadan during dry and wet seasons were considered.
