New 2DV laboratory data on moisture-pressure dynamics above groundwater wave. Laboratory data cover different oscillation periods ranged from 268 s to 2449 s. Hysteretic Richards’ equation was solved numerically considering seepage face formation. Data was used to evaluate numerical solution of hysteretic Richards’ equation. Model can qualitatively reproduce observed moisture-pressure dynamics.
