| Abstract: | Soil–hydrophysical research substantiating the mathematical models of water movement, taking into account the soil heterogeneity, due to the vertical change in texture, is considered. The vertical movement of water on large-size lysimeters of the Federal Scientific Center of Agroecology of the Russian Academy of Sciences (Volgograd) was studied. The influence of statistical heterogeneity of hydrophysical parameters of lysimeter substrates was studied on models of water transfer dynamics and formation of gravitational runoff developed in the HYDRUS-1D software package. The change in texture along the vertical profile of the lysimeters and the related variability of the main hydrophysical characteristic or water retention curve (WRC) were taken into account. The textural heterogeneity of the substrates was estimated by the scaling method, according to the scale factors of the WRC parameters, assuming a normal probability distribution of the logarithms of the pore space capillary radii between soil particles. The effect of texture on water holding capacity, boundary and initial conditions, intensity of gravitational runoff and cumulative accumulation of water were studied. [ABSTRACT FROM AUTHOR] |
