Soil erosion assessment using geomorphological remote sensing techniques : an example from southern Italy

Auteur(s) et Affiliation(s)



Description :
The aim of this study is to assess of the distribution and map the geomorphological effects of soil erosion at the basin scale identifying newly-formed erosional landsurfaces (NeFELs), by means of an integration of Landsat ETM 7+ remotely sensed data and field-surveyed geomorphological data. The study was carried out in a typical Mediterranean area located in southern Italy. The study area was first characterized from a lithological, pedological, land-use and morpho-topographic point of view and thematic maps were created. Then, the georeferenced Landsat ETM 7+ satellite imagery was processed using the RSI ENVI 4.0 software. The spatial analysis showed that the highest frequency of the NeFELs occurred on both south-facing and southwest-facing slopes. The comparison of two satellite imageries of different periods highlighted that the NeFELs were most clearly evident immediately after summer tillage operations.
