La morfologia del versante in funzione dei processi morfogenetici in aree calanchive: l’esempio della Sicilia settentrionale

FROM SLOPE MORPHOMETRY TO MORPHOGENETIC PROCESSES: AN INTEGRATED APPROACH OF FIELD SURVEY, GIS MORPHOMETRIC ANALYSIS AND STATISTICS IN ITALIAN BADLANDS

Calanchi (singular calanco) represent a typical example of badlands in the Italian peninsula, which rapidly evolve on clayey terrains such as the widespread Pliocene-Pleistocene marine clays. The present study aimed at investigating the role of the slope morphometry on the typology and distribution of morphogenetic processes in a calanchi area located in southern Italy. The research included detailed geomorphological surveying, morphometric and statistical analysis. The study area was first subdivided into individual hydrographic units (HUs), for which field survey allowed to identify the dominant denudation processes, their intensity and the distribution of the associated landforms (pipes,…
