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.
