Simulating Infiltration Into Sand From a Trickle Line Source Using the Matric Flux Potential Concept

We used a simulation model based on the matric flux potential concept to describe two-dimensional infiltration from a line source. The model showed considerable stability with varying compartment sizes and trickle discharges. The simulated wetting patterns indicated closer agreement with published experimental data than did alternative models, especially under high rates of trickle discharge.
