WebJul 1, 2024 · The Green-Ampt (GA) model has been widely used to evaluate soil water infiltration. While a simple piston profile is commonly used, the wetting profile of a soil changes during infiltration and a quarter-ellipse has been found to better describe its evolution. This study aims to improve the GA model and discuss the model parameters … WebJul 23, 2024 · Green-Ampt (GA) infiltration model (Green and Ampt 1911) is one of the most commonly used models to describe the infiltration process which has a simple structure, requires few parameters, and has ...
