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.

целокупне падине. Стабилност пре примене техничких мера и генерална стабилност
падине са примењеним мерама испитивана је методом Janbu-а, а локална стабилност
методом Bishop-а. Провера стабилности зида извршена је у погледу претурања и
хоризонталног померања. Ове анализе извршене су применом софтвера GEO5
(Geotechnical software). Аналитичким путем извршена је и анализа носивости земљишта
испод потпорних зидова методом Brinc Hansen-а. Два решења испунила су задате
критеријуме, решења I са факторм сигурности Fs = 1,81 и решење II Fs = 1,75. Анализа
носивости земљишта показала је да темељено тло може безбедно да прими оптерећење

AB  - In this paper, the stability analysis before and after the application of technical solutions was performed on a landslide located on the Stolicе-Krupanj route, in the western part of the Republic of Serbia. The landslide also affected part of the road, so the movement of traffic was difficult. Several solutions of the gabion retaining wall and the leveling of the slope affected by the landslide were analyzed. The selection of the optimal solution is based on the fulfillment of two criteria: the stability of the structure and the stability of the entire slope. The stability before the application of technical measures and the general stability of the slope with the applied measures were examined using the Yanbu method, and the local stability using the Bishop method. The stability of the wall was checked in terms of overturning and horizontal movement. These analyzes were performed using GEO5 software (Geotechnical software). Analytical analysis of the load-bearing capacity of the soil under the retaining walls was carried out using the Brinc Hansen method. Two solutions met the set criteria, solution I with a safety factor Fs = 1.81 and solution II Fs = 1.75. The analysis of the bearing capacity of the soil showed that the foundation soil can safely receive the load from the structure in the case of both solutions. Solution II was selected for the optimal solution for landslide rehabilitation.

AB  - Rainfall simulators are important instruments in soil research. In 2019 we have constructed and calibrated
portable field spraying rainfall simulator for a research of effects of changes in soil moisture content on
changes in mechanical parameters of soil and formation of surface runoff and soil erosion. Also, we have
constructed a dripping rainfall simulator with one dripper for the research of splash erosion and calibration
of hypodermic needles for a further development of dripping rainfall simulator with a more than one dripper
for research of rainfall impact and runoff on soil erosion. Beside that we are in a process of modifying
portable field spraying rainfall simulator in term of drops falling height and size, giving us a greater
possibility in the application and analysis of soil erosion. In the paper we will represent our results and
experience gained through the literature analyses and the process of construction and calibration of rainfall
simulators for our research. We have analyzed process of development rainfall simulators, conducted an
analysis of the design and performance of the current dripping rainfall simulators, while collecting data and
creating a database related to the design and performance of spraying rainfall simulators improving our
understanding of research needs and simulator abilities to simulate natural rainfalls. Such approach is pushing
us toward to harmonization of some future rainfall simulators improving and facilitating data analysis of soil
research all around the world. Scientific research in which rain simulators are used, and which can be applied
in the fields of hydrology, agriculture, forestry, as well as in other industrial branches, are becoming
increasingly necessary and frequent.

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  - Degraded areas of forests, due to the action of erosion processes, have a reduced capacity to perform ecosystem services and a reduced production potential of wood mass. In order to achieve an appropriate solution for remediation, it is necessary to determine the elements of the mechanisms of erosion processes, by analyzing the physical and mechanical parameters of the soil. Experimental soil testing has conducted using a portable field rainfall simulator in the forest area in the gullies and the conditionally stable zone of the gullies’ banks. It’s been observed the effects of changes in soil moisture on changes in the mechanical parameters of the soil, as well as the formation of surface runoff and soil erosion. It was established that the change in the current soil moisture affects the change in the mechanical parameters of the soil. The values of soil shear resistance and resistance to penetration are lower in tests in gullies, compared to tests on gullies’ banks. The presence of cracks and macropores influenced the appearance of rapid infiltration of part of the precipitation into the soil, 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 soils of the research area are sensitive to erosion processes when they are in a state of low natural humidity. With an increase in humidity above 20%, the soil becomes more sensitive to erosion processes and other forms of physical degradation. After an increase in the current humidity above 42% (the average value of the liquid limit), the soil is in a saturated state when the resistance forces cease to act.

AB  - Land degradation caused by erosion processes is a widespread global problem. Rain simulators are one of the tools often used to determine the resistance of soils to erosion processes. The aim of this publication is to present the process of the construction and calibration of a small, portable field simulator which would be implemented in research studies designed to determine the changes in the soils’ shear strength parameters in forested areas (in situ) caused by a change in soil moisture content achieved by the rain simulation. The constructed simulator consists of a metal frame, sprayers (with specific nozzles), a sediment funnel/tray made of metal, water and a sediment collector unit, a water tank and pump, and a set of rubber hoses, manometer, valves, reducers, adapters and other supplementary equipment. The calibration was carried out by using the pluviometric method. The choice of nozzles was based on the criteria of low water consumption (losses), the Christiansen uniformity coefficient (CU) and the possibility of achieving specific downpour intensities for the investigated area. The further calibration of the device consisted of determining the raindrop diameter and the distribution of the rainfall when the simulator is positioned on the slopes (7° and 15°). The achieved rain intensity was 1.7–1.9 mm/min, with a CU of 92.23–93.70% for the raindrop diameters equal to 1.2 mm. The kinetic energy of the simulated rain (Ke) was 2.82∙10. The constructed simulator proved itself to be in accordance with all of the given criteria, and it can successfully be implemented in research studies aimed at determining the resistance of forest soils to erosion processes, infiltration, and sediment yield.

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.

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.
