Abstract: By considering the phenomena of subsurface irrigation as a case of two-dimensional infiltration, a method is developed for analyzing the water distribution pattern in the soil profile from a subirrigation pipe placed on a barrier. Equations of soil-water movement were used to establish the design criteria of the discharge, the burial depth and the spacing of the subsurface irrigation system. A numerical example is given to show the procedures of the proposed method for subsurface irrigation system analysis and design.
