Water flow and solute transport in top soils are important elements in many environmental studies. The agro- and ecohydrological model SWAP (Soil-Water-Plant-Atmosphere) has been developed to simulate simultaneously water flow, solute transport, heat flow and crop growth at field scale level. The main features and theoretical concepts of SWAP are d...
In het kader van de bouw van het nutriëntenuitspoelingsmodel STONE is aan Alterra, RIZA en RIVM verzocht gezamenlijk nieuwe hydrologische randvoorwaarden als invoer voor dit model toe te leveren. Hiertoe is een ruimtelijke schematisering van met name het topsysteem van de ondergrond gemaakt in zogenaamde unieke combinaties. Voor het ontwerpen van d...
Water repellent soils are known to inhibit water infiltration, ultimately forcing water to flow via preferential paths through the vadose zone. To study water flow and transport in a water repellent sandy soil, a bromide tracer experiment was carried out, which started in the fall, after winter wheat had been sown. Field average soil water content ...
Soil tillage is the manipulation of soil which is generally considered as necessary to obtain optimum growth conditions for a crop. In the same time the resulting modification of soil structure has serious implications for the behaviour of the soil to erosive forces by water and wind. In Chapter 1 an introduction is given to the most important aspe...
