Abstract


Se llevó a cabo el seguimiento morfológico del litoral entre Ceuta y Cabo Negro (NO de Marruecos). Las playas estudiadas presentaron perfiles reflectivos que mostraron escasa variabilidad estacional, estando los cambios más importantes (del orden de 20 m3 m?1) relacionados con la acción de los temporales. Los parámetros geomorfológicos utilizados evidenciaron la presencia de playas intermedias y reflectivas caracterizadas por roturas en voluta. Sólo a veces, tras los temporales, se observaron playas más disipativas. Finalmente, las playas que presentaron mayor variabilidad fueron aquellas que se encuentran próximas a estructuras antrópicas.

A beach monitoring program was carried out along the littoral between Ceuta and Cabo Negro (NW Morocco). The beaches studied showed reflective profiles that recorded little seasonality and the most notable morphological changes (about 20 m3 m?1) were related to storm waves. Morphological parameters highlighted the existence of intermediate and reflective beach states, which are characterized by plunging breakers. Dissipative conditions were observed only in a few cases, after severe storms. The beaches that showed the most variability were usually those located close to human structures.
