FIG. 3. The impact of water repellency on the simulated behavior of two locations (grid node 1003 at 75-cm horizontal and 30-cm vertical distance, and grid node 1089 at 87.5-cm horizontal and 32.5-cm vertical distance) during the rewetting phase. The time 0 is the start of the rewetting phase. Water repellency is not considered for A–B and is considered for C–H. Simulation without considering water repellency: (A) Matric heads and actual contact angles (dashed line) at node 1003. (B) Volumetric water contents at node 1003. Simulation with considering water repellency: The pore surface properties are on average 
max 90° ± 20° and min 5° ± 1.5°; at node 1003 they are max = 93.6° and min = 5.27°; at node 1089 they are max = 67.1° and min = 3.28°. Node 1003 is outside of fingers and node 1089 is inside a finger. (C) Matric heads and actual contact angles (dashed line) at node 1003. (D) Volumetric water contents and actual contact angles (dashed line) at node 1003. (E) The values of the parameter 
vG during the simulation and the actual contact angles (dashed line) at node 1003. (F) The values of the parameter nvG during the simulation and the actual contact angles (dashed line) at node 1003. (G) Matric heads and actual contact angles (dashed line) at node 1089. (H) Volumetric water contents and actual contact angles (dashed line) at node 1089.
