Description :
The Torrente Piantrafolla sample area was chosen as representative of the study area; it was most recently monitored during the period Nov. 2000 - Feb. 2004. At this time morphographic and morphometric analyses carried out in selected measurements station located on slopes, identify gravity as the main morphogenic process responsible for slope shaping. The calanchi badland areas are characterised by constant and rapid shrinking of their edges resulting from landslides which occur in autumn and winter as a consequence of intense rainstorms. Results and discussion on the erosion rate, comparison between 1976 and 1994 digital elevation models obtained from photogrammetric restitution.
