This work is a Doctoral study of the University of Alberta which describes the flow-field upstream of the hydropower dams, with emphasis on the application of temperature control curtains. By reviewing the available literature, it is concluded that the near intake flow-field upstream of the hydropower intake systems can be modeled by the potential theories. This near intake flow-field can be useful in fish entrainment study and in designing fish repulsion systems. To maintain downstream river temperature, a flexible curtain was installed upstream of several dams in California. Flow downstream of the curtain is analyzed using a Computational Fluid Dynamic (CFD) solver and flow upstream of the curtain is analyzed using potential flow theories. In this part, a theory based on Schwarz-Christoffel transformation is developed to predict the flow-field upstream of the curtain. Effect of stratification on line sink is also analyzed. A theory is developed to predict the incipient withdrawal...
