2D Water Quality Modeling of Dam Reservoir (Case Study: Doosti Dam)

Due to the developments in the field of computer sciences, numerous models have recently been developed for hydrodynamic and water quality assessment in water-bodies. Among these models, the two-dimensional laterally averaged CE-QUAL-W2 has received considerable attention worldwide and has become a commercial model in the recent decade. Considering the model’s abilities and the need to study the Doosti dam, the present study examines the water quality parameters of the Doosti dam Reservoir, such as phosphorus, Nitrate, etc., over a year-long period. The model was calibrated and yielded satisfying results, especially in the case of water temperature. Here, the results for the period from 2013 to 2014 have been presented. The results showed a three-month thermal stratification in the reservoir. Also, results of quality parameters showed that the Doosti dam reservoir is in danger of eutrophication.
