    Gravity-driven fingered flow in porous media is recognized to be an important process with respect to solute transport in the unsaturated zone. Recent continuous and nondestructive measurements of water content distribution in a water-repellent sandy field soil in the Netherlands reveals a very complicated wetting pattern with fingered flow being quite prevalent. Recent success in modelling gravity-driven unstable flow enables the complicated patterns observed at field sites to be simulated. In this study an attempt is made to simulate the patterns observed at the water-repellent field site using a numerical solution intended for modelling gravity-driven unstable flow.
