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  - Dripping rainfall simulators for soil research generate water drops with different types of drippers, such as plastic and glass tubes, drippers in a form of holes, irrigation drippers and hanging yarn, among which metal tubes are the most commonly used. Metal tubes appear in the form of capillaries with a flat tip or in the form of hypodermic needles. Hypodermic needles are suitable for this purpose because their diameter size is standardized with relatively small deviations from the standardized dimensions, they are available on the market, relatively cheap, made of stainless material and have a threaded connector (Luer taper). However, very often the descriptions of the rainfall simulators were not complete, nor was the calibration of the needles. In order to conduct calibration and define water drops diameter for different hypodermic needles size and dripping speed, it was constructed rainfall simulator with one dripper in a form of hypodermic needle. Simulator was designed in accordance to research of Rončević et al., (2022), needle calibration research and future soil research requirements. Simulator was intended primarily for laboratory use. It consists of structural support, water tank, water pump, mechanism of water flow regulation and simulator operation, water tank with dripper and dripper. Calibration was conducted for 11 different needles, ranging in size from 16 G to 32 G (G – gauge number), at different dripping speed, using drop counting sensor. Water drops are measured using weight measuring method. Obtained water drops size ranging from 3.70 to 1.48 mm. Based on research data, two nomograms were made for determination of interconnected parameters of potentially simulated rainfall: water drops size under different dripping speed, drippers discharge, number of drippers, and kinetic energy of water drops for the given falling height. The results of research provide the data necessary for the design of future dripping rainfall simulators for soil research and use of hypodermic needles as drippers.
