Van Genuchten Model

The Van Genuchten model describes how water moves through soil and how much water soil can hold at different levels of moisture. It uses mathematical formulas to relate the soil’s water content to the pressure needed to extract or hold the water. This model helps scientists and engineers predict things like how efficiently plants can access water or how water drains in the ground. It’s widely used because it accurately captures the complex behavior of water in unsaturated soils, providing insights for agriculture, environmental management, and hydrology.
