Four types of soil data, each with a characteristic reliability, are proposed for point observations and areas of land. Distinctions are based on procedures by which data are obtained: (i) measurement; (ii) estimation by experts; (iii) calculation by

The relevance of bypass flow on water flow, solute or pesticide transport is becoming increasingly recognized. Recent investigations proved that soil salinization may be influenced by bypass flow, i.e. the rapid transport of water and solutes via mac

Bypass flow and its role in leaching of raised beds under different land use types on an acid sulphate soil

Autor: M.E.F. van Mensvoort, J. Bouma, H.W.G. Booltink, To Phuc Tuong, L.Q. Minh

Agricultural Water Management 32 (1997)

A better understanding of leaching processes in raised beds is useful in assessing management options for acid sulphate soils. Field and laboratory studies were carried out to quantify the effects of soil physical properties and bypass flow on leachi

Field-scale distributed modelling of bypass flow in a heavily textured clay soil

Autor: H.W.G. Booltink

Publikováno v: Journal of Hydrology 163 (1994)
Journal of Hydrology, 163, 65-84

Water transport in structured soils is influenced strongly by macropores. This study developed a water transport model to simulate bypass flow processes on the field scale. The LEACHW-model was extended with subroutines describing bypass flow, tortuo

Journal of Hydrology 135 (1992)

Methylene blue staining patterns of five undisturbed unsaturated soil cores, 200 mm long and 200 mm in diameter, taken from a well-structured clay soil classified as a Hydric Fluvaquent, were characterized by using the fractal dimension of structure
