This book was released on 1967 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A desk study and a laboratory scale-model study were made of the feasibility of using high resolution, very high frequency (VHF) mapping techniques to detect the presence of tunnel complexes such as occur in Vietnam. Detailed descriptions of proposed airborne systems for such detection are given. An evaluation of the feasibility of using these systems for tunnel detection was made by considering the known capabilities of existing radar systems for a similar purpose and the specific results of this scale-model study which involved the use of cylindrical and L-shaped Plexiglas rods submerged in water to simulate tunnels approximately 1 m in cross section buried beneath wet soils at depths of as much as 10 m. The results of the study indicate that tunnels could be detected in areas characteristic of a large part of Vietnam using the airborne systems described. (Author).

Book Synopsis Rock Fractures and Fluid Flow by : National Research Council
Download or read book Rock Fractures and Fluid Flow written by National Research Council and published by National Academies Press. This book was released on 1996-08-27 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific understanding of fluid flow in rock fracturesâ€"a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storageâ€"has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
