Résumé :
|
By their very nature, permeable media and thus the transport phenomena taking place in them are highly complex. Often, finding solutions to practical problems calls for close cooperation between experts from different fields. In recent years, highly complex theories and methods, based on novel concept of non-linear wave propagation have been developed, verified and successfully applied in chemical, petroleum and environmental engineering. Yet, a truly comprehensive understanding of migration and fate of chemicals in soils and subsoils and an ability to make reliable predictions have not been fully obtained. The authors (from European and Americain countries) are experts in soils and environmental sciences as well as in theory of wave propagation and numerical modeling, and practical use of such knowledge and models for guidance in disposal operations, preventive measures to minimize ecological damage, prediction of consequences of sepage, and design of rmedial actions.
