Abstract
The research yielded the following conclusions and results: preferential flow can be expected in recently deposited, loosely packed, wettable dune sands; preferential flow is common in most water-repellent sandy soils; distribution flow in topsoils isa process of major importance, resulting in a spatially heterogeneous distribution of water and solutes in soils; with the potential water repellency parameter soils can be compared with respect to their sensitivity to water repellency; a two-dimensionalwater flow model, including hysteresis, has been developed, which is able to simulate finger growth and persistence.
