The close almost functional relationship of the erosion rate and, hence, the erodibility of model soil samples with the temperature of the water used in the experiments has been shown. This suggests that the rupture of bonds between the particles of eroded soil samples is due to the electrostatic forces appearing between the monomolecular water layers around the adjacent soil aggregates similarly oriented with respect to the soil solid phase rather than to the hydraulic forces. The erosion parameters of the samples also strongly depend on the soil moisture. The lowest erosion rate of the heavy loamy chernozem samples is observed at an initial water content of 22–24%. The erosion rate increases and the variability of the results is reduced with both decreasing and increasing the initial water content.
