The study was performed on a catchment area of approx. 150 ha, mainly for agricultural use, with steep slopes, with intense erosion and associated processes. The arrangement proposal was made after establishing the erosion risk, the degrees of intensity and the spatial distribution of this process. In order to determine the average annual soil loss and then the alluvial influx, the U.O.R. (Homogeneous Relief Units) procedure was chosen: for each U.O.R. the ROMSEM equation was applied successively, adapted for our country by acad. M. Moţoc. In this approach, the GIS technique was used by using Geo-Graph software, by creating spatial bases and processing by overlay technique (7 information layers were created). The attribute database was created taking into account all the factors involved in the erosion process, the parameters characterizing the climate, the relief, the soil, the land use, the technologies of agricultural exploitation, etc. The main purpose of the paper is to demonstrate that the complex action of monitoring and management of lands affected by various degradation processes can only be done correctly within a Geographic Information System - GIS.
