The morphodynamic control on coastal drivers at plan and profile scales presents differences of various orders of magnitude both in time and space. This is due mainly to the different associated physical processes (refraction, diffraction, depth induced breaking and friction, …) which act at various scales. The paper analyzes the morphodynamic control in both plan and profile scales using practical examples from the Ebre delta coast (in the Spanish Mediterranean). During these analyses, some conclusions have been derived regarding the effect of hydrodynamic processes over the probabilistic distributions and their parameters.
