Abstract: A green element formulation was developed for horizontal flow as found in furrow irrigation. The model was tested on clay and sandy soils. An integral equation was developed using a one-dimensional horizontal equation for flow through unsaturated soils. The integral equation was implemented by discretize the soil column into elements. The values of the soil water content and the fluxes were obtained directly from the formulation. The soil water content profiles obtained were compared with that of vertical infiltration under the same condition.
