Abstract

The work deals with the effects that the storm surges of December-1995 and January-1996 made upon the beaches of Cádiz Bay (SW Spain). From the incident-wave analysis it can be deduced that the effects are much stronger when the surge peak coincides with maximum tidal ranges. The morphological changes recorded in the beaches are studied through pre- and post-surge profiling of both natural and artificially nourished beaches. The quantification of such morphological transformations shows that the initial beach profile is determinant in the kind of response of the beach to high wave-energy conditions. The erosive processes upon dune ridges are represented by gullying, overwashing, etc. The final estimation of losses in the beaches reveals higher damages in zones where anthropic preassure is higher.
