The ResSaMMè project was set up by six European partners (Italian, French, Spanish and Greek) who decided to pool together their experience. The goal is to exploit the technical tools available when analysing the characteristics and potential use of natural sand resources on the continental shelf within their regions, therefore slowing down erosion along the Mediterranean coasts. This should result in the guidelines required to develop a common protocol which will define the standards and terminology and also take research strategies into account. The project, based on of the outcome of the European BEACHMED (Interreg IIIb – Medocc) and the «Ipotesi di linee-guida per la ricerca in mare di masse sabbiose da utilizzare per il ripascimento dei litorali soggetti ad erosione» (Guideline Options for research at sea of sand masses to be used for the beach nourishment of eroding coasts) paper written by "La Sapienza” Rome University together with Genoa University, aims to evaluate the potential availability of sand and gravels in the submarine deposits of participating countries. This includes new and existing sources whose main characteristics are to be analysed in order to verify their suitability for beach nourishment activities for the various coastal areas. Finally, a summary of partners’ experience in this field will contribute to the creation of a methodological protocol which can be used for this type of research and analysis (main results). Coastlines of countries involved will benefit directly from the project. Thanks to the sustainability of results and the opportunity to transfer initiatives to other European coastal zones with similar problems the project will have a positive impact on the future, and will create the foundations for further research and development.
