Wave climate modelling south of Rio de Janeiro in Brazil

A verified accurate numerical model for wave propagation in nearshore regions is used to study wave transformation and to predict the wave climate in the coastal area south of Rio de Janeiro in Brazil. The sea state is represented by a group of monochromatic waves. The existence of several groups of islands in the nearshore region adds complexity to the physical processes of wave transformation when waves travel shoreward. Such complexity requires the application of an adequate numerical model like the one used in this study. Results obtained reveal the effects of the islands in the process of wave propagation and the resulting variation of exposure to wave action along the beach.
