Abstract
A photogrammetric study employing geostatistical techniques was carried out to detect changes due to hydric erosion in slopy termines. Photogrammetry allows accurate measurements of spatial coordinates to be made with any disturbance of natural conditions. With the experimental points, given by Photogrammetry, digital elevation models (DEM) were generated in different seasons (end of summer 1997 to spring 1998). Geostatistical techniques also have helped to optimise the measuring network and make estimations of the errors in the DEM’s. This approach can be used to detect areas where erosion takes place, but also those zones which are being filled with sediments (mainly the gullies developed by torrential rainfalls in summer 1997). Comparison between DEM’s has allowed for the quantification of the volumes of material involved in these processes.
