Coastal zone is the Earth sector which involves Waterscape Archaeology, recent branch of Archaeological studies which provide a new approach to the environment with a total comprehension of the context. Environments consists of natural landscapes and cultural landscapes, altered in some manner by people. Among archaeologists, the term landscape can refer to the meanings and alterations people mark onto their surroundings: landscape archaeology is often employed to study the human use of land over extensive periods of time, waterscape archaeology is a multidisciplinary science devoted to the study of human use of wet lands, coastal zones, anthropological connection with the water environment: the study of the ways in which people in the past constructed and used the water environment around them. A new approach of scientific synergy with geomorphological analysis, biology and water environmental conditions studies associated to archaeology, history, ancient sources (texts, inscriptions, cartography), data coming from aerial and satellite photos has been great to map the sites and promote new strategies of use and conservation. RWT Researching While Training method following the international CMAS standards and UNESCO legislation has brought excellent results. In this cultural ambit we developed a pilote Research / Didactic Project called WAS Waterscape Archaeology in Sicily at Isola delle Femmine, Palermo, Italy, under the patronage of Soprintendenza del Mare, Regione Siciliana, Assessorato Beni culturali e Identità siciliana, Dipartimento dei Beni culturali e Identità siciliana, Dept. of Cultural Heritage, University of Padova with its Underwater Archaeology Laboratory. The project concerns researches, studies, protection, conservation, tutela of the coastal cultural heritage, with an ecosustainable approach, best practice for scientific diving, beginning from total respect of nature across a deep knowledge of the context and of the site. The campaigns completed between 2016 and 2018 has been very successful. More than 30 points of cultural interest attested, a new proposal for responsible tourism and conservation for protected marine areas. The Project, through the organization of 3 European events, is recognized by European Commission Environment and Energy European Commission as Partner for Satellite Event of EU Green Week and Energy Week. In this conference we would like to introduce our unpublished work, bringing an example of collaboration between different disciplines to safeguard and promote the coast as cultural resource.
