Salt concentration and water content profiles were intensively measured within an area of 40x7 m2 to a depth 1.0 m in a sandy (Ando) soil. A few models were considered to simulate salt movement in the soil. Comparison of simulation results with the field experimental data showed that the convective dispersive (CD) model with effective parameters well describes the mean concentration profiles.

Abstract

Salt concentration and water content profiles were intensively measured within an area of 40x7 m2 to a depth 1.0 m in a sandy (Ando) soil. A few models were considered to simulate salt movement in the soil. Comparison of simulation results with the field experimental data showed that the convective dispersive (CD) model with effective parameters well describes the mean concentration profiles. The failure of other models is probably due to the neglect of pore scale dispersion, which in the considered experiment seems to have a relevant impact.
