Analysis of hydrophysical properties of soils using pore-network models
Бюллетень Почвенного института им. В.В. ДокучаеваModern soil physical models traditionally consider the pore space as static; however, new visualization techniques, such as X-ray tomography, have revealed structural dynamics that can intensively change under the influence of moisture and temperature ...
