E. Mention d'édition : IWC Editeur : IWC Année de publication : 1978 ISBN/ISSN/EAN : CI-03699 Note générale : This moisture characteristic and the unsatured hydraulic conductivy are calculated from the measured water pressures at different depths in a soil core and the weights during evaporation at the top of thecore the mesured water presure is assumed to represent the mean preasure to be described with sufficient accuracy by a polynon in each pressure interval is solved from a set of equations. Assuming the hydraulic conductivity - water pressure relation ship can be described by an exponentiol relationship with varying constants in the different pressure at two deppths and three sequential moments, and the rate of change in water content below some definde depth in the core during two sequential time periods. In the satured conductivity is relatively hight, a steady-state infiltartion method is applied to determine the unsaturated hydraulic conductivity at high water Langues : Anglais (eng) Mots-clés : Methodologie  Infiltration  Hydraulique  Eau  Evaporation  Humidité  SOL  Pédologie  Système automatique  Théorie Index. décimale : 621.2 Hydraulique : turbines, pompes, accumulateurs, transmission hydraulique Résumé : This moisture characteristic and the unsatured hydraulic conductivy are calculated from the measured water pressures at different depths in a soil core and the weights during evaporation at the top of thecore the mesured water presure is assumed to represent the mean preasure to be described with sufficient accuracy by a polynon in each pressure interval is solved from a set of equations.
