Abstract
Solving problems of anti-erosion technology and machinery design is associated with finding an integral objective parameter that would meet piratical requirements and develop an acceptable determination method. Therefore, the research objective is to develop an integral criterion to determine soil erosion potential (SEP). As a value to characterize SEP it is prosed to use energy ΔА expended to erode and remove the unit weight of a soil mass Δm under specific conditions of its occurrence. Consequently, the development of theoretical prerequisites for the problem under consideration, as well as the experimental determination of ΔА and Δm, can reveal the main regularities in the physical mechanism of erosion processes. We propose to use the thermodynamic potential method to describe soil erosion processes. It has been shown that the Gibbs thermodynamic potential is the most suitable for this purpose since it is possible to design devices for the experimental measurement of independent variables. SEP is an additive and constant value for a given soil and expresses its properties, i.e. it can be adopted as a single integral criterion for assessing the resistance of soils to erosion.
