A modified analytical modeling of horizontal solute transport through unsaturated soil

Abstract EN

The analytical mode) proposed by Smiles cl at.

(1978) to describe solute transport through unsaturated soil has been modified, by solving ihe governing equations using integration limits in the vicinity of the solute front, to enable deferminmg the exact location of the wetting front as a function of both time and length, For verification purposes, the results obtained using the proposed analytical approach were compared with those ohtained using numerical method.

The proposed approach was found very successful in pre- dicting solute transport through unsaturated soil.

Therefore, the modified ana- lytical approach is an effective predictive tool in horizontal solute transport through unsaturated soils.
