abstract The experimental validation of bypass flow submodel was done using data gathered at two sites Grab6w and Czes3awice. Measured and calculated moisture content show better agreement when the bypass flow is taken into account. This is especally important for deeper layers of the soil where the Richard's equation modeling shows too small water content. The bypass flow mechanism allows more water to flow down immediately to deep layers bypassing the top layers of soil profile.
