Résumé

For each flow modeling in the unsaturated soils, it is necessary to determine the retention curve and the hydraulic conductivity curve of studied soils . Some empirical models use the same parameters to describe these two hydraulic properties. For this reason the estimation of these parameters is achieved by adjusting the experimental points to the retention curve only, which is more easily measured as compared with the the hydraulic conductivity curve. In this work, we show that the adjustment of the retention curve θ (h) is not generally sufficient to describe the hydraulic conductivity curve K (θ) and the spatio-temporel variation of the moisture in the soil θ (z). The models used in this study are van Genuchten- Mualem (1980-1976), Brooks and Corey (1964), for two different soils; Gault clay and Givors silt.
