Abstract

This study aims at defining a general method for identifying, in karst coastal settings, the elevations of flat or low topographic gradient surfaces (using morphometric analysis of Digital Elevation Models (DEMs) and geographical information systems (GISs), and their comparison with elevations of distinctive karstic levels (passages, lateral solution cavities) observed in vertical shafts and horizontal caves. The method is applied to a regional coastal carbonate formation in southern Italy, by using a 10 m DEM and information on 140 complex caves and 85 shafts. Of the 15 elevations above sea level indicated by DEM analysis, 13 match clearly those highlighted by significant frequencies of distinctive karstic levels. These elevations are validated by comparison to the elevation of terraces and karst plains indicated in the literature
