Environmental Geotechnology
The term "Environmental Geotechnology" was introduced in 1986 at Lehigh by Professor Emeritus of Geotechnical Engineering Dr. Hsai-Yang Fang to help explain the diversity of geotechnical phenomena unexplained by the classical soil mechanics compaction test as defined by Karl Terzaghi. Famous tests performed in Fritz Lab with the Baldwin test machine on garbage bales stimulated the formulation of the term.
