Abstract: The Salamonde Hydroelectric power scheme is located in the north of Portugal, within the Cavado river mountainous basin, and is one of the seven powerplants of Cavado-RabagaoHomem hydropower system. The original Salamonde scheme began industrial operation in 1953 and recently EDP took the decision to repower it by means of a new 209 MW reversible scheme (Salamonde II). Several scale hydraulic model studies of the main hydraulic structures were performed. The paper presents the basic design studies and the description of the outlet structure and downstream channel scale model tests as well as the results obtained.
