The simulated seepage fields for the ground surface boundary condition with 2 m negative pressure at time of :
(a) 0.012d, (b) 0.0185d, (c) 0.0198d, (d) 0.02d, (e) 0.022d and (f) 2d. (The pressure water heads are in black and red. The red line represents zero pressure which indicates the water table and the inverted water table curves respectively. Total water head is in green and flow directions are indicated in arrow).
