That is why, scientists and engineers have spend continuous efforts in order to develop the knowledge about the hydrodynamic, ecological and morphologic characteristics of the coastal area specifically of the nearshore zone. In this study, an experimental work has been done in order to obtain oxygen rates along a shoaling region and it has been obtained that great amount of oxygen has been transferred especially in the vicinity of breaking conditions.<P>
