ИСТИНА

The hypothesis of the analysis of the water retention curve (WRC) with the help of the so-called “cutting lines” or simply “Voronin’s interceptors” is the theoretical part of the WRC analysis in soil hydrophysics. A.D. Voronin, on the basis of a large experimental material and an analysis of the known theories of the rheological behavior of soils, suggested description of soil moisture state by straight lines in the axes pF – mass moisture. In justifying the "interceptors" A.D. Voronin proceeded from the physical essence of the phenomenon of equilibrium soil moisture and rheological states of the soil. Modern hydrological pedotransfer functions are mainly statistical in nature, not taking into account the physical justification of the phenomenon.
