Santa Catarina Island bays (SCI bays) have a great economic and social importance in the region. With more than 700,000 habitants in its surroundings, besides touristic and fishery activities, it represents approximately 70% of the Brazilian bivalve shellfish production. In order to understand processes controlling the water quality and food availability, relevant for the shellfish production, it is unquestionably important to understand the main hydrodynamics patterns of SCI Bays. Thus, the first step was to characterize the hydrodynamics of the SCI bays via observations and using the numerical model MOHID. An acoustic Doppler current profiler (ADCP) was deployed in two different locations, during a period of one lunar cycle each, in order to obtain a time series of water level, currents velocity and direction, which were then used to validate the model. The model was forced with astronomical tides and measured tides to evaluate the meteorological tide influence. Results from the model using both, measured tides and astronomical tides, show index of agreement for water elevation of 0.98 and 0.88 for the month of May and 0.96 and 0.73 for the month of July, respectively. The best results for the relative mean absolute error and the index of agreement for velocity V were from the simulation forced with measured tides, in July, with results of 0.07 and 0.80, respectively. Based on the results, the hydrodynamic model forced with measured tide will be used to drive the water quality model for bacteriological dispersion and decay.
