Abstract One of the essential issues in quality management water resources is determination level eutrophication and dissolved oxygen dam reservoirs other bodies. It possible to study changes concentration using qualitative models. In this study, CE-QUAL-W2, a two-dimensional model hydrodynamics capable predicting behavior aquatic ecosystems, has been used simulate eutrophication. As case Yamch...
