    Abstract

    Water flow and transport through the vadose zone of water-repellent field soils take place mainly through preferred flow paths. For modelling purposes, it is essential to know when fingers can be expected and what their average dimension is. Thereforeten soil blocks, each 1.2 m long, 0.6 m wide and 0.52 m deep, were sampled in a water-repellent sandy field soil. Fingered flow patterns were distinct in soil blocks sampled after rain events. Fingers were found where the degree of potential water repellency in the upper part of the soil was low.
