Abstract

The aim of this geomorphologic study was to analyse the recent morphologic evolution of calanchi badlands over a 50 years' period (1955-2006) and to evaluate the mean erosion rate in areas situated in Southern Tuscany. These areas are characterised by Pliocene marine claystone which have undergone and continue to undergo erosion processes and a rapid morphologic evolution. This morphodynamic investigation was based on systematic field surveys conducted over a 12 years' period (1994-2006) and photogeological analysis of a 30 km2 area. The results indicated that the effects of graviatational processes have increased over the last 10 years while sheet-wash action has been less intense over the same period. In addition, the morphodynamic analysis strongly suggest that anthropogenic action should not be underestimated as a major force in shaping the landscape in the study area over the last 50 years
