Data of Is the combination of linearized theoretical analysis and sand column experiment always suitable for estimating the complex effective porosity?

Sand conlumn experiments were conducted to describe time-varying pore water pressure. Height of the sand column is fixed as 50 cm and three pore water pressure transducers were deployed along the sidewall of the sand column at 46 cm, 38 cm, 30cm, 22 cm, 14cm, 6 cm below the sand surface, respectively.
