Abstract
The quality of the water resources is facing threats because of continuous urbanization. This
increase in human activities around the river areas changed the water quality, affecting the
aquatic ecosystem. Eutrophication occurs when high levels of nutrients cause algal bloom. The
water quality modeling can be a useful tool for assessing water bodies. The quality of the Ravi
River has deteriorated during the past decades due to inappropriate sewage systems, so the aim
of this research was to make a one-dimensional model to model the river water quality in terms
of CBOD and DO concentrations. The results of the model were compared to the available
literature on this river, as it was the only available data. The results showed the poor quality of
the waters of the Ravi River in terms of high CBOD concentrations (200 mg/l), according to
the International Water Quality Guidelines for Ecosystems (IWQGES) estimates, World
Health Organization (WHO), and EPA Pakistan. These results were consistent with the
previous studies, and thus HEC-RAS can be considered as an effective tool for modeling river
water quality.
