Heterogeneity and Scaling in Geologic Media: Applications to Transport in the Vadose and Saturated Zones

摘要

The DOE National Laboratories have extensive environmental remediation and operations centers as well as research teams specializing in environmental problems. These organizations are concerned largely with pollution prevention, safe disposal of hazardous materials, polluted site identification and characterization, and cleanup of polluted sites. These organizations, and the private-industry subcontractors they hire, require state of the art tools and techniques for characterization and monitoring. Our research will contribute to this effort by providing descriptions of heterogeneities and scaling properties in the vadose and saturated zones with particular emphasis on flow and transport. This work will also provide an important link between some geophysical measurements and fluid transport characteristics.
