Book Description
Research has been in progress since July 1970 to determine which geophysical and remote-sensing methods offer the most promising results for detecting subsurface cavities and what might be done to further develop them. Through extensive field tests, it has been determined that none of the standard electrical resistivity procedures give consistently good results. As a result of the initial field testing, a new process of data interpretation has been developed for one specific electrode configuration. Cavities less than 10 feet in diameter and at the depths greater than 100 feet were located. Research is continuing to adapt this process for locating water- or mud-filled cavities.

Book Description
The research is part of a program underway to evaluate remote sensing instrumentation and methods for locating subsurface cavities that can cause serious highway construction and maintenance problems. Three methods of subsurface cavity detection based on different geophysical techniques were experimentally evaluated, including ground-penetrating radar, gravity profiling, and earth resistivity profiling. Tests were conducted at three sites having different geological environments. Verification tests showed all methods to be capable of locating air-filled cavities.

Book Description
This handbook is primarily a description of the methodology of using earth resistivity techniques for locating cavities. Only a small portion of the handbook will be devoted to the theoretical considerations behind these techniques. However, the annotated bibliography cites ample literature to satisfy the needs of the theoretician. Along with earth resistivity techniques, several geophysical techniques will be examined in lesser detail with respect to cavity location. Micro-gravity, high-resolution seismic reflection profiling, and ground probing radar were selected because they show good success rates in cavity detection. High-resolution seismic profiling shows particularly good promise as an effective tool in cavity location. Techniques in photo interpretation will also be discussed with regard to possible cavity location.

Book Description
Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

Book Description
The first international symposium on NDT-CE (Non-Destructive Testing in Civil Engineering) was held in Berlin, Germany in 1991. Successive symposia were held throughout Europe until 1997. This, the 5th symposium is organized as SEIKEN SYMPOSIUM No. 26, and is sponsored by the Institute of Industrial Science, at the University of Tokyo, Japan. Original objectives of the NDT-CE symposium have been to provide an opportunity for discussing current issues and future perspectives of NDT and for promoting mutual understanding among engineers and researchers. Asia is one of the key regions for further development in NDT and this symposium in Japan will be a good opportunity not only to exchange technical information on NDT, but to promote worldwide friendship between engineers in Asian countries and other nations of the world. This volume contains 70 papers providing the most recent research results and findings. The papers are grouped under the following areas: (1) keynote papers, (2) magnetic / electric, (3) steel structures, (4) integrated test, (5) moisture, (6) strength, (7) acoustic emission, (8) various tests, (9) ultrasonic, (10) impact echo, (11) radar, (12) quality and (13) corrosion / cover.
