This paper presents the outcomes of a research on water erosion quantification by GIS-based mathematical stimulation and modelling, carried out in a water catchment area from Romania. This paper presents the outcomes of a research carried out in a water catchment area with high slopes, where intense processes of water erosion emerge. The researchers in this field successfully use two models. The first one is USLE, within GIS Geo-Graph software and the second one is WEEP; the simulation was done in a GIS ArcView environment. The simulation and application of simulation models take place in the same water catchment area (perimeter), under the same conditions and within the same range imposed by each model. This paper contains an analysis of the outcomes and concludes on the visible differences. The USLE model stalling was done by direct measurements in the bordering area of a reservoir, where the silt depositions were measured. As a follow-up to this project, the WEEP model will also be stalled in the water catchment area subjected to study, by using aerophotograms and field data.
