  abstract = {{I}n this work, we conducted two laboratory column experiments on an undisturbed sandy soil. {T}he first deals with a percolation-drainage experiment whereas the second deals with an infiltration of a constant water flux at the surface of the unsaturated soil. {A} {B}ayesian assessment of the soil parameters is performed for both experiments with the {M}arkov {C}hain {M}onte {C}arlo ({MCMC}) method using measurements of pressure head inside the column and cumulative outflow collected during the experiments. {T}he results show that both experiments can be well reproduced with the mathematical model based on the {R}ichards equation and the van-{G}enchten/{M}ualem models. {F}urthermore, the inversion of the two laboratory experiments yields similar results in terms of mean estimated parameter values but strong discrepancies occur between confidence intervals used to quantify uncertainty on the estimated parameters. {C}ompared to the percolation-drainage experiment, the infiltration experiment yields more accurate parameters with narrower uncertainty regions.},
