AB  - For the purposes of researching the influence of rainfall factors on soil shear strength, i.e. soil
erosion resistance, research was conducted on plots measuring 1.0x0.3 m at a slope of 15°, with
equally prepared soil. It’s been carried out 12 rainfall simulations with different values of rainfall
factors (rainfall intensity and drops diameter). These simulations were carried out with a modified
rain simulator with sprayers by Živanović et. al (2021). The analysis of the uniformity of the
prepared soil, as well as the examination of the influence of simulated rainfall factors on soil
erosion, was carried out by measuring with a pocket vane tester (Eijkelkamp M1.14.10.E). The
measurement was carried out at 30 regularly spaced locations on every plot, immediately after the
simulation was completed. Also, the measurement was carried out after 24 hours in three places
(upper, middle and lower third of the plot). Spatial distribution of measured values was assessed
by Christians' coefficient of uniformity CU. The measured shear strength values of the prepared
soil range from 2.1 to 6.9 kN/m2. The shear strength values immediately after the simulation range
from 0.4 to 5.4 kN/m2, while after 24 hours they range from 2.4 to 8.1 kN/m2. The CU values of the
prepared soil range from 68% to 81% (average 75%). Immediately after the simulation, Cu values
range from 73% to 83%, while after 24 hours, from 69% to 91%. In general, there is a clear trend of
decreasing values measured with the pocket vane tester from the top to the bottom of the plots.
Also, the influence of the change in soil moisture on the values of soil shear strength was
observed. The change in rainfall factors affects the change in soil resistance to erosion.

AB  - Due to the action of erosion processes, degraded areas of forests have a reduced capacity to perform ecosystem services and a reduced production potential of wood mass. In an attempt to reduce such negative effects, one of the steps is to determine the elements of the mechanisms of erosion processes in order to achieve an appropriate solution for remediation by analysing the physical and mechanical parameters of the soil. Using a portable field rainfall simulator in the forest area in the gullies and the conditionally stable zone of the gullies’ banks, experimental soil testing has conducted. Тhe simulator that was used is based on the pop up sprinkler system described in detail by Živanović et al. (2022). The limited amount of water on the field, as well as the duration of the pouring rain for the study area, affected the duration of each test to be limited to 10 minutes. During the experiment, the effects of changes in soil moisture on changes in the parameters of soil shear resistance and resistance to penetration, as well as the formation of surface runoff and soil erosion, have been observed. Research has been conducted during the spring and autumn. It was established that the change in the current soil moisture affects the change in the mechanical parameters of the soil. Compared to tests on gullies’ banks, the values of soil shear resistance and resistance to penetration are lower in tests in gullies. The presence of cracks and macropores influenced the appearance of rapid infiltration into the soil of part of the precipitation, which resulted in small amounts of runoff water on the exit profile (3.76–32.71% of the total volume of rain). Surface erosion occurs in the form of tearing off entire microaggregates and their transport via micro-furrows to the outlet profile. The concentration of sediments in the water, during tests on the banks, tended to decrease with each subsequent repetition. It’s been determined that soils of the research area are sensitive to erosion processes when they are in a state of low natural humidity. With an increase in water content above 20%, the soil becomes more sensitive to erosion processes and other forms of physical degradation. After an increase in the current water content above 42% (the average value of the liquid limit), the soil was in a saturated state when the resistance forces cease to act.

AB  - 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.

AB  - Soil erosion is the most prevalent form of soil degradation both in the world and in Serbia. Degraded forest ecosystems do not provide sufficient soil protection and often large areas are affected by erosion processes. Shear stress plays an important role in assessing soil resistance to erosion processes. The investigated area is located in the southwestern part of Belgrade, whose areas under the forest are exposed to intense erosion processes. The entire surface is crisscrossed by gullies and shallow landslides. 13 profiles on gullies were selected, where soil resistance was measured with hand-held devices at three points along the profile (left bank, gully, right bank) and two depths each. Handy devices were chosen for field measurements: pocket wing probe (Eijkelkamp model M1.14.10.E) and pocket (hand) static penetrometer (Eijkelkamp model M1.06.03.E). The paper presents mechanical parameters measured with hand-held devices with a range of values of soil shear strength τ = 11.58 – 172.42 kN∙m-2 and pin penetration resistance R = 159.36 – 441.30 kN∙m-2. A statistical dependence was established between the values obtained by wing probe and penetrometer measurements, with a correlation coefficient of r = 0.65 and a determination coefficient of r2 = 0.42. The established differences in the values of soil resistance to shear, at the selected measurement points, as well as the established dependence, indicate the possible application of hand-held devices for determining the soil resistance of forest ecosystems to erosion processes.
AB  - Ерозија земљишта је најзаступљенији облик деградације земљишта како у свету тако и у Србији. Деградирани шумски екосистеми не пружају довољну заштиту земљишта те су често велике површине захваћене ерозионим процесима. Важну улогу при оцени отпорности земљишта на ерозионе процесе има напон смицања. Истраживано подручје лоцирано је у југозападном делу Београда чије су површине под шумом изложене интензивним ерозионим процесима. Читава површина испресецана је јаругама и плитким клизиштима. Одабрано је 13 профила на јаругама на којима је извршено мерење отпорности земљишта приручним апаратима на три тачке дуж профила (лева обала, јаруга, десна обала) и по две дубине. За теренска мерења изабрани су приручни апарати: џепна крилна сонда (Eijkelkamp модел M1.14.10.E) и џепни (ручни) статички пенетрометар (Eijkelkamp модел M1.06.03.E). У раду су приказани механички параметри мерени приручним апаратима са опсегом вредности чврстоће земљишта на смицање τ = 11,58 – 172,42 kN∙m-2 и отпора при продору игле R = 159,36 – 441,30 kN∙m-2. Утврђена је статистичка зависност између вредности добијених мерењима крилном сондом и пенетрометром, са коефицијентом корелације r = 0,65 и коефицијентом детерминације r2 = 0,42. Утврђене разлике у вредностима отпорности земљишта на смицање, на изабраним мерним тачкама, као и утврђена зависност указују на могућу примену приручних апарата за одређивање отпорности земљишта шумских екосистема на ерозионе процесе.
