This work presents the Solanas’s beach evolution, sedimentary and dynamic study results, which followed up a monitoring activity between years 2001 and 2007. The study started with a bibliographic research of the whole area and were reached by revising previous echographic and sedimentary data, used to produce a first seabottom’s map. New surveys were carried out by high precision instruments, according to the methodological standard references of the European Project Interreg IIIA GERER, in order to evaluate the sedimentary dynamic and the evolution of the area. Collected data allowed the realization of wave and hydrodinamic models with dedicated software, in order to understand the circulation systems produced by the different meteomarino events recorded in the area. This study allowed to define the sedimentological set and to identify which meteomarine events mainly influence the beach dynamic. Solanas beach was classified as “intermediate-dissipative” with a significative advance trend. Bars and troughs zone (surfzone) can extends up to 1 km from the shoreline. The Mistral and Libeccio wind events were the most significant. Sediment samples were mainly classified between “very coarse sands” and “medium sands” with siliciclastic composition.

Abstract
This work presents the Solanas’s beach evolution, sedimentary and dynamic study results, which followed up a monitoring activity between years 2001 and 2007. The study started with a bibliographic research of the whole area and were reached by revising previous echographic and sedimentary data, used to produce a first seabottom’s map. New surveys were carried out by high precision instruments, according to the methodological standard references of the European Project Interreg IIIA GERER, in order to evaluate the sedimentary dynamic and the evolution of the area. Collected data allowed the realization of wave and hydrodinamic models with dedicated software, in order to understand the circulation systems produced by the different meteomarino events recorded in the area. This study allowed to define the sedimentological set and to identify which meteomarine events mainly influence the beach dynamic. Solanas beach was classified as “intermediate-dissipative” with a significative advance trend. Bars and troughs zone (surfzone) can extends up to 1 km from the shoreline. The Mistral and Libeccio wind events were the most significant. Sediment samples were mainly classified between “very coarse sands” and “medium sands” with siliciclastic composition.
