Abstract

DISPERSIVITY is a measurable property of a geologic system and one of the parameters of advection-dispersion equation. In this research, the dependence of DISPERSIVITY on SOIL THICKNESS is investigated in coarse and medium HOMOGENEOUS SANDs. Experiments were carried out in a rectangular laboratory-scale Plexiglas tank, 0.72 m long, along which the main flow was imposed, 0.1 m wide and 1.2m high. A solution containing 8 g/l (Ec=14 ds/m) sodium chloride concentration was used as the nonreactive contaminant. Experiments were carried out with SOIL THICKNESSes of 0.1 m in sequence up to 1 m with an increment of 0.1 m. Dispersivities obtained from the analysis of breakthrough curves data ranged from 0.31 to 0.64 cm for coarse sand and 0.13 to 0.46 cm for medium sand. The results indicate that DISPERSIVITY is independent of SOIL THICKNESS in the coarse and medium sands investigated.
