Abstract: Erosion processes are commonly found on the sloping lands of the North Caucasus region during crop growing operations. The processes are caused by a particular combination of natural conditions. Climatic conditions, topography, geological structure, soil features and vegetation cover are of equal significance. The effect of climatic conditions on erosion processes is diverse, but the precipitation and wind are crucial in the case. Thus, the study was conducted to substantiate the main analytical patterns that characterise soil erosion. The basic principles of higher mathematics, theoretical mechanics and strength of materials were the basis for the study. Analytical dependencies were identified to establish the final velocity of a falling raindrop, taking into account the influence of the wind on the trajectory of raindrop movement since rains are often accompanied by winds with a high speed. The study also established a dependence of the angle of incidence for a raindrop on its diameter at different wind speeds. A mathematical expression was obtained to calculate the time of raindrop fall depending on the height of the rain clouds. The trajectories of movement for a raindrop with a diameter of 5 mm were plotted at various wind speeds (5, 10, and 15 m/s).
