Due to the increase in global energy consumption and the search for diversification of the energy matrix, there has been an increase in research related to renewable energy sources. The energy contained in sea waves stands out when it comes to renewable sources. Then, the present study aims to analyze the influence of wave channel bathymetry on the generation and propagation of realistic irregular waves and representative regular waves of the sea state that occurred in Tramandaí, in the state of Rio Grande do Sul, Brazil. Thereunto, two geometries were considered for the wave channel: with an inclined bottom (representing local bathymetry) and with a flat bottom. The computational fluid dynamics software, FLUENT, which is based on the Finite Volume Method, was employed in the numerical simulation of the wave channels. The Volume of Fluid model was used for the treatment between the phases, which are water and air. The WaveMIMO methodology was used to generate realistic irregular waves, while 2nd order Stokes Theory was considered to generate representative regular waves. The results showed that the generation and propagation of both realistic irregular waves and representative regular waves presented greater accuracy when considering the wave channel with an inclined bottom.
