dc.description.abstract | Natural processes and anthropogenic activity threaten soil as a resource. Soil degradation is a global problem intensifi ed by climate change, population growth and economic development. Soil erosion is one of the most prevalent forms of degradation in Serbia. Soil resistance to erosive processes largely depends on the soil‘s physical properties. Erosion processes aff ect changes in the physical characteristics of the soil. Therefore, the hypothesis is established: There is a diff erence between the physical parameters of soil aff ected by erosion processes and soil on which there are no visible indicators of the action of these processes.The investigated area is located in the southern, hilly part of Belgrade, in a degraded forest area vegetated by Hungarian and Turkey oak (Quercetum frainetto – cerris). Intensive landslide and gully erosion processes aff ect this area. The mechanism of occurrence of the erosion process is piping-erosion. Thirteen transverse profi les were selected on gullies where soil sampling was performed. Sampling was performed on each profi le in the gully bed, in the left and right banks at two fi xed depths, zone 1, depth 5–10 cm and zone 2, depth of 10–25 cm. Laboratory analyses included tests of volume weight, specifi c weight, soil particle size distribution, consistent states and humidity. Parameters porosity and clay activity were also analysed. Soil sampling and laboratory testing were done in accordance with SRPS.U.B1 geotechnical testing standards. The comparison of the obtained results was made between the banks and the gully bed, as well as between the zones using tests: t-test of mean values; W (Mann-Whitney; Wilcoxon) – median test. Hypothesis testing was performed with a signifi cance threshold p of 95.0 %. Testing was conducted in the statistical analysis program Statgraphics centurion XVIII (StatPoint Technologies, Inc. 2019). Comparison of soil parameters in zone 1 had shown a statistically signifi cant diff erence for percentage of clay and sand, liquid limit, humidity and clay activity. Results of conducted comparison showed that in the zone 2, a statistically signifi cant diff erence found for the parameter percentage of clay and sand, between banks and gully bed soil samples. While no signifi cant statistical diff erence found for the other parameters. Analysing the results between zones, a signifi cant statistical diff erence was found for the gully bed, left and right banks soil samples for the parameters volume weight (dry and humid) and porosity while for gully samples there was signifi cant statistical diff erence for liquid limit, plastic limit, humidity and clay activity. Comparing all samples of the zones 1 and 2, a signifi cant statistical diff erence was found for the parameters volume weight (dry and humid), porosity, percentage of sand particles, plastic limit and current humidity. | sr |
