CARG Project: land-sea geological cartography of the Campania Region coastal sectors.

In December 1999 the Regione Campania promoted its participation in the National CARG Project and co-financed the regional geological maps of emerged and coastal marine areas. The maps include the 0 -200 m depth and the related emerged coastal sector. These maps have been surveyed at 1:10.000 scale while a synthetic 1:50.000 versions was also derived for the National Project CARG. In this way, the use of same scale for the survey of emerged and submerged areas allow a land-sea correlation. Moreover the areas around the coastal in the Gulf of Naples have been mapped by direct methodology, by subacqueous geologist (bathimetric range from 0 to -30 m). This significant aspect for the study of submerged marine areas represent the establishment of homogeneous criteria for the geological survey between coastal emerged and submerged zones. The above mentioned criteria result in a tool to map in great detail, the underwater geology strategically useful for territorial planning procedures and risk evaluation in a densely anthropized environment with socio-economical value, characterized by high geomorphological dynamism and specific vulnerability. This modern land-sea geological 1:10.000 cartography of coastal sheets respond to new regional needs in order to face, consciously and responsibly, the complex problems of coastal sectors. This type of cartography has already been used for "Piano Stralcio dell'Erosione Costiera" dell'Autorità di Bacino del Sarno (today, Autorità di Bacino della Campania Centrale) and now form the basic data set for the integrated coastal planning of Campania region. At present, only part of the land-sea geological cartography of Campania Region has been printed and is avaliable (series of cartography of Campania region coastal maps in 1:10.000 scale) with the associated illustrative notes.
