Geomorphological processes in the Studineţ catchment (Tutova Hills)
Keywords:Studineţ catcment, geomorphological processes, gullies, sheet erosion, landslides
Studineţ catchment is situated in the eastern part of Romania (Tutova Hills), having a surface of about 9669 hectares. The land degradation in Studineţ catchment is mainly represented by sheet erosion processes, gully erosion and landslides. Gully erosion is the most characteristic geomorphological process, both by the occupied area and by the resulting effects, even if, overall, this process does not exceed the amount of soil losses, caused by sheet erosion The exploitation of GIS techniques and the use of aerial photos allow the diachronic analysis of large land surfaces. Departing from the digital elevation model (DEM) and from derived thematic maps constructed with the help of the TNT mips software, we have conducted a complex analysis of geomorphological processes in relationship with the control factors (rainfalls, slope, fragmentation depth, land use, etc).
