To the problem of mapping erosion processes

Abstract

Goal. To substantiate the application of data on the magnetic susceptibility (MS) of soils as a diagnostic criterion for the degree of their blur (erodibility). Methods. Laboratory, mathematical-statistical, geoinformation. Results The magnetic susceptibility of the soil is highly probable due to the distribution of humus content and the index of erosion hazard. Due to the established linear dependence (based on a limited sample - the catenary number of chernozems), the use of humus depletion schemes can be recommended similarly between humus content and the investigated indicator. The water-erosion structure of the investigated slope is grounded on the basis of the spatial distribution of the values of the investigated index. Conclusions By using the statistical link of the soil MS with the index of erosion hazard and the content of humus, circuits for determining the degree of blur (erodibility) on the basis of the researched indicator can be used, similar to those based on the reduction of humus content. Due to the expressiveness and lower cost of the method for determining the soil MC, it is possible to plot and substantiate the probable water-erosion structure of the slope on the basis of a denser systematic sampling grid.
