Although Richards' equation (RE) generally provides a good description of infiltration and water redistribution in soils, its numerical solutions can be computationally intensive or suffer from numerical instability and require extensive soil data. Simplified physically based approaches are often used in many practical settings after validation against RE used as a benchmark. The purpose of this research was to develop and test an approximated physical model for simulating transient point‐source infiltration and redistribution in a quasi three‐dimensional flow domain. An existing three‐dimensional Green–Ampt model that simulates only the infiltration phase is extended based on the one...
