Study of the relation between soil erodibility and hydrological characteristics

Abstract

Hydrological characteristics such as soil water retention curve and hydraulic conductivity, for which, however, there are no standardized measurement methods for the entire range of soil moisture, are most important for assessing the erodibility of soil. In the article, based on the energy approach to soil erodibility analysis, a relation was proposed linking the characteristic of soil erodibility, - the specific power spent on the destruction and removal of soil in the places of its natural occurrence, with soil hydrological characteristics. Modeling erosion processes based on the proposed ratio may allow both describing the erosion properties depending on the initial soil moisture and obtaining numerical information on the soil hydrological characteristics using measured values of soil erodibility characteristics at any time during the vegetation period.
