Simulation Num Rique De La Propagation D Un Polluant Dans Un Milieu Poreux Satur

Simulation numérique de la propagation d'un polluant dans un milieu poreux saturé

ON MET AU POINT UN MODELE NUMERIQUE D'ECOULEMENT-DISPERSION. ON UTILISE CE MODELE POUR MONTRER SUR UN EXEMPLE L'IMPORTANCE DES HETEROGENEITES DANS UNE ETUDE DE LA DISPERSION ET POUR ILLUSTRER LES PROBLEMES D'ECHELLE. ON PRESENTE UNE ETUDE EXPERIMENTALE ET ON DEVELOPPE UNE METHODE DE MESURE PAR TRACAGE PAR ELECTROLYTE ET MESURE DES CONDUCTIVITES PAR CAROTTAGE ELECTRIQUE.

Groundwater and Subsurface Remediation

The complex topic of in-situ subsurface remediation technologies has been ad dressed at an international symposium at the Universitat Stuttgart on September 26 and 27, 1995, on the occasion of the inauguration of the research facility VEGAS (Versuchseinrichtung zur Grundwasser- und Altlastensanierung). The results are contained in this book with 22 contributions from leading experts in the field from Europe and North America. The book illustrates the role of large-scale experiments in groundwater and subsurface remediation research. The subtopics address the various links between conventional laboratory experiments, technology-scale experiments and field-site studies, showing the contribution of large-scale experiments to bridging the gap between small-scale investigations and large-scale field investigations (upscaling). The interdisciplinary nature of the problems requires a multidisciplinary approach. Therefore, the idea has been followed to bring together the various disciplines in volved in the different aspects and facets of subsurface flow, transport and trans as hydraulics and hydrology, physics, formation, involving such diverse disciplines chemistry, microbiology, geology, industrial, chemical and hydraulic engineering, mathematics and hydroinformatics. The individual contributions from these di versified fields address the subject from different angles in an attempt to form a coherent picture of the various aspects of the complex problems of subsurface remediation. The focus is on research approaches and strategies with respect to the development of new and improved technologies and to the role of large-scale experiments in research and application.
