- •
New laboratory data on groundwater wave propagation in an unconfined aquifer.
- •
Laboratory data cover a wide range of oscillation period from 10.7 s to 909 s.
- •
Numerical solution of hysteretic and non-hysteretic Richards’ equation for all periods.
- •
A monotonic increase in the observed water table’s amplitude decay and phase lag.
- •
Qualitative discrepancy between data and existing theoretical and numerical models.
