Gullies constitute one of the most characteristic elements
of loess relief in SE Poland. Particularly dense net of
permanent gullies – in some places more than 10 km?km-2 –
appears in areas of specific conditions of abiotic environment
which favour gully erosion. However, it is generally believed
that these conditions were not a natural landscape (Bork
1989, Schmitt et al. 2006, Vanwalleghem et al. 2003). Only
after the devastation of the natural plant cover of mixed and
deciduous forests, resulting from agricultural expansion, the
erosion began to develop dynamically.
The purpose of this article was to determine the
influence of natural factors and human activity on the
processes of gully erosion (density of permanent gullies).
The existing gully systems were examined and the achieved
results give an idea about the processes taking place in the
past.
