Titre de série : Technical Bulletin (ILWMR), 111 Titre : A method to changes in Hydraulic conductivity caused by drainage plows and bacfilling of trenches Type de document : texte imprimé Auteurs : Boels, D. Mention d'édition : ILWMR Editeur : ILWMR Année de publication : 1979 ISBN/ISSN/EAN : CI-10542 Note générale : A method was developed to predict the reduction in hydraulic conductivity around drainpipes due to the laying technique. The relation between hydraulic conductivity and deformation was derived from cores placed in a triaxial apparatus. When the frictions angle is known, the reduction in hydraulic conductivity can be determined. Using a relation between density and hydraulic conductivity the reduction in conductivity is obtained.

Titre de série : Technical Bulletin (ILWMR) Titre : Calculation of vertical moistuce flow in a soil body during evaporation, infiltration and redistribution Type de document : texte imprimé Auteurs : Kastanek, F. Année de publication : 1973 ISBN/ISSN/EAN : CI-09957 Note générale : Water movement in soil is governed by two basic principles: the law of continuity, the law of resistance. Combination of these two principles gives a differential equation which can describe the movement of noisture in soils. With the aid of theoretical considerations it is possible to divide the soil profile into different zones, for each of which the boundary conditions can be defined. For each such zone one can calculate the distribution of noisture content and water potential using the law of continuity and the law of resistance in accordance with the boundary conditions...
