... hysteresis and menisci evolution in the test materials during wet–dry cycles were measured to interpret the WRC. The WEV of soil increased with decreasing chemical heterogeneity and particle size. When drying the hydrophobised soils, they could retain water before reaching a certain negative...

...Yosuke Higo; Ryunosuke Kido The hysteresis observed in a water retention curve was experimentally studied through the use of X-ray micro-computed tomography (μCT). The CT images were acquired during the main drying and wetting processes of a water retention test for uniform sand. The porosity...
