Download or read book Transfert par infiltration de l'eau dans les sols fins compactes non saturés. Etude de la diffusivité et de la conductivité hydraulique written by Okba Bentoumi and published by . This book was released on 1995 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'une des conditions que doit remplir une barrière étanche en site de décharge est de pouvoir assurer un coefficient de perméabilité inférieur à 10(exp)-9 m/s. La mesure de cette perméabilité pose actuellement de nombreuses questions auxquelles l'étude du transfert hydrique en milieu non saturé doit pouvoir répondre. Dans ce cadre, nous présentons des résultats expérimentaux relatifs à l'étude du transfert par infiltration de l'eau dans un sol fin compacté non saturé soumis à des conditions initiales et aux limites bien définies. Dans un premier temps, une étude paramétrique a été menée sur le limon de Givors ou des essais d'infiltration ont été réalisés sous des différentes conditions. Des enseignements tirés de cette étude ont permis de définir les différents paramètres qui peuvent influencer le transfert hydrique dans un sol non saturé, et de proposer un protocole d'essai pour la détermination de la perméabilité à saturation in-situ. Dans un deuxième temps, nous avons complété cette étude paramétrique par une série d'essais d'infiltration réalisés sur une colonne de sol de 225 mm de hauteur ou l'analyse des profils hydriques et des succions a été possible grâce au dispositif expérimental mis au point. Un deuxième protocole pour la détermination du coefficient de perméabilité in-situ a été proposé grâce à cette étude. La méthode des profils instantanés a été appliquée aux résultats des essais d'infiltration sur la colonne de 225 mm pour établir la relation entre la conductivité hydraulique et la teneur en eau. Les modèles de Mualem et Van Genuchten ont été testés.

This book was released on 1995 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 17-21 October 1994. The objective of the symposium was to assess the progress being made in the use of nuclear and related techniques for studying various aspects of soil fertility and plant nutrition, environmental problems, the potential and limitations of existing methods, and the possibilities for further development. Analytical methods and equipment are discussed, as are isotope dilution techniques, transfers of fixed N to non-fixing crops, crop water consumption, labelled fertilizer involving fertigation, 13C discrimination, erosion and soil degradation, and global warming and climate change. The proceedings should assist scientists, particularly those in developing countries, to find ways of increasing and sustaining soil fertility and crop production while preserving the environment.
