Percolation characteristics of a water‐repellent sandy forest soil
In a tracer experiment TDR transect measurements were made to study percolation behaviour in a 120‐year‐old pine stand (Pinus sylvestris) on a water‐repellent sandy soil (Haplic Arenosol). The

By limiting infiltration and facilitating preferential flow, water repellency in surface soils produces wetting patterns which differ substantially from those in comparable wettable soils. Seasonal
Variability of water repellency in sandy forest soils under broadleaves and conifers in north-western Jutland/Denmark.
Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been
A new modelling approach to simulate preferential flow and transport in water repellent porous media: Parameter sensitivity, and effects on crop growth and solute leaching
A modified version of the popular agrohydrological model SWAP has been used to evaluate modelling of soil water flow and crop growth at field situations in which water repellency causes preferential


How water moves in a water repellent sandy soil: 1. Potential and actual water repellency
Water repellency is an important property of many soils. It causes rainwater to penetrate into the soil as preferential flow paths, and solutes can reach the groundwater more rapidly than in the case
Distribution flow: a general process in the top layer of water repellent soils
Water and solute input rates on the soil surface may vary considerably from place to place. Distribution flow, i.e., the process of water and solute flow in a lateral direction over and through the
How water moves in a water repellent sandy soil: 2. Dynamics of fingered flow
The dynamics of fingered flow in a water repellent sandy soil was studied in the field by sampling 10 vertical trenches in a 1-year cycle. In dry soil, fingers were formed in those places in the top
A three-Region Analytical Model of Solute Leaching in a Soil with a Water-Repellent Top Layer
When water enters a water-repellent topsoil, fingers develop and a large part of the soil is bypassed. Therefore fingering is expected to accelerate solute leaching to the groundwater. In soils with
Recurring fingered flow pathways in a water repellent sandy field soil
Abstract. Field evidence of finger formation and reformation during Successive rain events over an eight months' observation period from June 1994 until January 1995 is presented. Fingered flow
