Abstract: The study analyzes the expected changes in the Paute River, located in Ecuador, as a result of the construction of the Paute-Cardenillo Dam. To evaluate the stability and safety of the structure, it is necessary to ascertain the shape and dimensions of the scour generated downstream. The scour is studied with three complementary procedures: empirical formulae obtained in models and prototypes, semi-empirical methodology based on pressure fluctuations-erodibility index and computational fluid dynamics (CFD) simulations. A preexcavated stilling basin is proposed and analyzed.
