Environmental geotechnology is a relatively new and interdisciplinary subject, which covers soil, water and rock and their interaction with various environmental cycles including the atmosphere, biosphere, hydrosphere, lithosphere, as well as geomicrobiosphere. To tackle this complex subject, it is necessary to have knowledge from other disciplinary fields including agricultural science, biology, environmental science, geology, microbiology, mineralogy, and physicochemistry. Therefore, a uniform glossary of terms, definitions, nomenclature, abbreviation, acronym, symbols and units is needed for general discussions, reports and documents to minimize confusion and to improve the effectiveness for the environmental aspects of geotechnical problems. Some important information is collected, compiled and edited, and in spite of careful preparation of this dictionary, there cannot be avoided some missing or misinterpreted terms, typing errors, etc. The editor hopes, however, that with the aid of suggestions and criticism, there can be improvement for a later edition.
Thanks to many government agencies, professional societies and private organizations including American Society of Civil Engineers (ASCE), American Society for Testing and Materials (ASTM), Transportation Research Board (TRB), International Society of Environmental Geotechnology (ISEG), U.S. Environmental Protection Agency (EPA), U.S. Department of Energy (DOE) for providing useful documents for preparation of the dictionary. Also thanks to Prof. Charles Ochola, Villanova University, Prof. Tae-Hyung Kim, Korea Maritime University, Ms. Eleanor S. Nothelfer of Fritz Engineering Laboratory, Lehigh University and Mr. Gustavo Borel Menezes of Global Institute for Energy and Environmental Systems (GIEES), University of North Carolina at Charlotte for their assistance during various phases of preparation of the manuscript.
Acknowledgment is made to Review Committee Members for their time and willingness to review the manuscripts.
