Use of sea wave containment techniques

Abstract

This work makes a comparison between different wave control methods applied in coastal cities, using a small-scale experimental model. The coastal zone of Brazil extends over a considerable area and covers a significant portion of the national territory. It is common to find a variety of constructions on the seashore, from large buildings to small kiosks, many of which are irregular, as they do not follow the proper authorizations from the competent authorities, resulting in environmental, social and economic problems. The coastal environment is dynamic, subject to constant changes in its configuration, since the waves transport and deposit sand, even in small quantities. However, human activity has accelerated this process, although it is natural. Therefore, some methods have been developed to mitigate it.
