Geomorphology of Cinque Terre National Park (Italy)

This work presents the outcomes of the geomorphological investigation and mapping carried out within the Cinque Terre National Park (38 km2), an outstanding example of a human-modified landscape. Over the centuries, the natural landscape of Cinque Terre has been almost completely modified by slope terracing for agricultural purposes. Extensive field surveys, topographic maps examination and aerial photographs interpretation have led to the production, within a GIS environment, of a new geomorphological map at 1:18,000 scale which outlines the main genesis and related landforms and deposits: (i) gravity-induced features, (ii) fluvial and runoff features, (iii) coastal features and (iv) anthropogenic features. Special attention has been given to the mapping of terraced slopes, which at present are extremely vulnerable to gravity-driven processes and running water because of extensive farmland abandonment. The output map is a fundamental basis for future activities of hazard assessment and zonation and the definition of land management strategies.
