A study of slope stability of agrolandscapes |

Agricultural production on slopes should be based on elaborate soil protection technologies that meet the specific requirements of mountain farming and optimal for mechanization of production processes. It should also be borne in mind that the technology of mountain agriculture need to be flexible and adaptive to rapidly changing environmental conditions. Consequently, complexes of machines for mechanization of technological processes must meet these requirements.
Thus, the system of measures on involving sloping agricultural lands in agricultural production should provide high crop productivity, a comprehensive mechanization of technological processes and, most importantly, prevention of water erosion of soils occurring under the action of precipitation.
Based on this complex task in this paper we theoretically investigated the impact of rainfall on the soil. Analysis of the results of previous studies showed that the defining characteristic of precipitation that affect the processes of erosion, should be considered the ultimate speed of the raindrops. A theoretical study was carried out taking into account the influence of the wind, as the rains are often accompanied by winds of high speed.
Analysis of the results shows that in terms of slope cultivated lands significantly increases the value of the horizontal component of impact force, which is the reason for the gain here erosion processes.
Theoretical relations and the results presented in this article can be used in the development of technical measures for the protection of sloping agricultural lands from erosion processes, and technical means for their implementation.
