Resumo: | In a previous article (1969), the author demonstrated, through the use of a hydrostatic model and of the Boussinesq hypothesis, the importance of some non-linear terms in the formation of inner fronts; this model provides a criterion for the easing and intensification of the slope of a simple wave according to the wave's upshore conditions. In this article, the use of a regular perturbation method enables us to free ourselves both from the long wave hypothesis and from the Boussinesq hypothesis. The theoretical model we created demonstrates the importance of non-linear terms in the formation of secondary oscillations upshore from the front. A phenomenon which was extensively observed in the eastern part of the Gibraltar straight. As the parameters of the model had been set to depict the conditions in the straight, the lengths and characteristic times recorded for these oscillations are very close to those previously observed.
