 A numerical tidal stream energy assessment study for Baía de Todos os Santos, BrazilMartinho Marta-Almeida, Mauro Cirano, Carlos Guedes Soares and Guilherme C. Lessa Renewable Energy, 2017, vol. 107, issue C, 271-287 Abstract: Estuaries may have ideal technical conditions for tidal energy conversion: strong currents and proximity to the coast and urban/industrial infrastructures. This is the case of the estuary Baía de Todos os Santos, for which a numerical tidal potential density assessment was done. This study used a high resolution numerical configuration of the ocean model ROMS forced with realistic surface and lateral forcing, as well as with tides and river discharges into the bay. Strong currents were found along the main axis of the bay, particularly at the centre and left side of the bay’s main entrance, and for a considerable time fraction. In these regions, speeds higher than 1 m s−1 were found during about 30% of the time leading to a power density around 1300 W m−2 at the surface layer, reaching peaks higher than 2500 W m−2. The energetic flow at the left side of the inlet is affected by a remarkable sand ridge, the St. Antonio Bank, which intensifies the flow between the shoal and the coast.
