Abstract

Coastal erosion is a natural phenomenon that is becoming a growing problem along coastlines around the world. In this research, the evolution of Poniente Beach, Benidorm (Spain), has been studied, which presents a different morphological behaviour depending on the area analysed. To do this, an analysis of shoreline evolution using aerial images has been carried out first. And, secondly, waves and incident storms have been studied. From the results obtained, the eastern zone of Poniente presents higher rates of erosion than the western zone, where in addition to a cross-shoretransport, a longshore transport of sediments is detected. This erosive trend disappeared in the last analysed period due to a change in the wave regime. A decrease in the frequency of waves coming from the east caused a decrease in erosion and stopped the tilting produced on the beach. In this situation, it is necessary to decide what solution to apply: carry out a nourishment similar to that of 1991 or make periodic maintenance of the beach? The accurate knowledge of the mentioned factors will provide adequate tools for its future management.
