Architectonical and archaeological heritage GIS-based risk map of high Agri river valley (southern Italy).

This paper is part of a wider research project on "Territory safeguard and cultural heritage conservation in Basilicata in relation to landscape development and geomorphological risk factors" carried out by National Research Council-IBAM in the high Agri river valley, southern Italy. The whole architectonical and archaeological heritage of several urban centers has been identified, analyzed and catalogued in a geodatabase, in order to structure a webGIS platform. The project concerns a thematic that has a regional and national scale of importance and its topic is the defense and the conservation of Cultural Heritage (historical, monumental and archaeological sites). The aim is to start analyzing landscape dynamics, to compare them with natural and anthropic transformations and finally to evaluate the impact caused by extreme natural events, such as landslides, floods or earthquakes, on monumental sites and buildings. The main aim of this project, focused on the case study of Marsico Nuovo Municipality, is to define the Cultural Heritage (architectonical and archaeological) risk map, which is the necessary basis to plan interventions of preservation and conservation of that Cultural Heritage mainly exposed to natural risks. The study was finalized to individualize the historical and architectonical heritage, expression of structural vulnerability V, as well as to map the landslide phenomena as expression of hazard H natural factor. The overlapping of these two different levels permitted to defining the risk map using a matrix.
