Sicily
Opis:: A GIS+analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels.

Tutova basin
Opis:: The present study approaches gully erosion in Tutova basin (south-central part of the Moldavian Plateau, Eastern Romania), mainly with the help of GIS and remote sensing by using the TNTmips 7.3. software. For this purpose a GIS was created, that integrates the Digital Elevation Model, geologic and morphometric maps, climatic and soil data, land use information and others. The assessment of risks associated to gullying has monitored several indicators, grouped as follows: gully-head advance and probability of affecting objectives located upstream; dynamics of gully banks; areal gully growth and loss of agricultural land; flooding and sedimentation of the land or social and economical objectives situated downstream the gully.

Opis:: Current soil erosion models do not solve the impact of gully erosion on the landscape changes but only its spatial distribution and intensity. Distributed process-based model SIMWE (Mitas & Mitasova 1998) and landscape evolution module (Burton et. al. 2010) was used for simulation of gully erosion consequences in GIS environment. The results of simulation within the assigned initiation condition in the past showed the real situation at the present time. Simulation process corresponded with the theoretical knowledge about gully development. Modification and combination of selected module procedure and of erosion model has shown the potential of the presented method to predict effectively the genesis of gullies.
