THE THEORICAL TEMPORAL STRUCTURE OF THE LONGSHORE CURRENTS

Abstract

For a better Knowledge of the causes about the littoral solid transport is essential to experience advances in the littoral hydrodynamic. In this field the longshore currents are may be who play the most important role due to the intensity, the distribution and the relative duration of them, causing the movement of the solid particles due to the suspension of them and the friction in bottom. The first theorical formulation about the longshore currents were established by Bowen (1969), Longet-Higgins (1970) and Thornton (1970). Previously another works trated an aproximation about the problem, obtaining a little precise results basing his works in simplest formulations, it shows in Sonu et alt. (1966).
