Gully erosion is one of the major threats to soil resources in Hungary, and may impair their ability to deliver a range of ecosystem goods and services. This study elaborates a model for mapping gully erosion hazard in two Hungarian microregions (Medves and Volgység) using spatial database and GIS. Slope, soil and land cover parameters were combined to create erosion risk maps. The SRTM, the CORINE land cover database and the Hungarian agro-topographi- cal database, the AGROTOPO were available from both regions and used in the study. In the Medves microregion most of the gullies are located on steep (17%<) N-NW slopes, meanwhile in the VOlgyseg gentle (5-17%) S-SW slopes are more common. Thus, among the important factors of slope inclination (Medves) the parameters like arable land and bess covered areas on gentle slope surfaces (Volgység) also favour erosion. Erosion risk mapping is a very useful tool to identify areas for soil conservation planning and sustainable management. Further research in different regions is needed to verify and improve our model of estimating gully erosion. [ABSTRACT FROM AUTHOR]
