FIG. 2. The distribution of volumetric water contents at three times during the simulated drying–rewetting cycle (B, D, E; right-hand side) with and (A, C, E; left-hand side) without considering water repellency. Locations where the actual contact angle is above the minimum contact angle (reduced wettability) are marked by dots. (A, B) End of the drying phase: after 20 d without precipitation and at a constant potential evapotranspiration rate of 0.42 cm d–1. (C, D) Start of the rewetting phase: after 2 d with a constant precipitation rate of 2 cm d–1. (E, F) End of the rewetting phase: after 7 d with a constant precipitation rate of 2 cm d–1.
