Though it provides abundant benefits to society, it also has environmental and ecological consequences. Dam construction significantly alters natural flow conditions. Fish numbers decline and other aquatic life may be adversely affected, especially during migration and reproduction cycles, due to degradation of their natural habitat. High summer water temperatures in hydropower reservoirs and elevated total dissolved gas (TDG) concentrations in downstream tailrace regions can increase mortality rates of fish passing through the dam. This study proposes to develop a numerical model to improve the prediction of hydrodynamics and water-quality parameters in hydropower flows. The main focus is to simulate temperature dynamics and TDG distribution in the McNary Dam forebay and tailrace. Existing numerical temperature and TDG models, developed by Politano et al. (2008, 2009c), were improved and implemented into the open-source CFD code OpenFOAM. These newly developed …
