Evoluzione della foce del Volturno e del litorale circostante da cartografie storiche e recenti

Volturno mouth and Campania neighbouring shores are characterised from time by morphological modifications that in the last decades have caused a great cost-line withdrawal. To plan actions for limiting these phenomena and their impacts, a detailed cognizance on dynamics and relative consequences on territory and environment is indispensable: reconstruction of changes occurred to fluvial mouth and coastal morphology, or, in other terms, quantitative determination of variations, must be realised. The use of historical and recent maps is fundamental, taking into account representation accuracy. This paper concerns the methodological approach adopted to compare morphological data included in different cartographic documents, such as historical and recent maps produced by IGMI (Istituto Geografico Militare Italiano), Campania Region, and CasMez between 1876 and 1998. Taking into account heterogeneity of these documentations, to realise comparisons of their contents, all data are related to the same datum (Gauss-Boaga Roma40).
