GSP 97 contains 17 papers on in situ geotechnical testing presented at sessions of Geo-Denver 2000, held in Denver, Colorado, August 5-8, 2000.

Site characterization is a fundamental step towards the proper design, construction and long term performance of all types of geotechnical projects, ranging from foundation, excavation, earth dams, embankments, seismic hazards, environmental issues, tunnels, near and offshore structures. Geotechnical and Geophysical Site Characterization 4 provides practical applications of novel and innovative technologies in geotechnical and geophysical engineering, and is of interest to academics, engineers and professionals involved in Geotechnical Engineering.

The theme of this collection of conference proceedings on geotechnical site characterization is to promote the exchange of innovative ideas, new technology and practical applications related to all aspects of site characterization for geotechnical and geoenvironmental engineering.

The topic of site characterization is unique to geotechnical engineering and owes its significance directly to the variability of the natural geologic deposits on the earth’s surface. Proper site characterization requires an understanding of various field and laboratory investigation methods. The book discusses the suitability of various methods under different site conditions and presents the procedures to derive design parameters based on interpretation of test results. Recent developments in specialized site characterization methods (such as seismic hazard evaluation) are also included. Three recent case histories are presented, where site characterization played a key role. The three disparate cases include soft natural soil under static loading, coarse and fine-grained soil under seismic impact, and hazardous waste deposits under both static and seismic loading. Site investigation requirements of building codes are discussed and guidelines for preparing a typical site characterization report are presented. The book is aimed at the practicing geotechnical engineer, as well as advanced undergraduate and graduate students.

This book comprises the select peer-reviewed proceedings of the Indian Geotechnical Conference (IGC) 2021. The contents focus on Geotechnics for Infrastructure Development and Innovative Applications. The book covers topics related to soil behavior and characterization of geomaterials, geotechnical, geological, and geophysical investigation of special topics such as behavior of unsaturated soils, offshore and marine geotechnics, remote sensing and GIS, instrumentation and monitoring, retrofitting of geotechnical structures, reliability in geotechnical engineering, geotechnical education, codes and standards, among others. This volume will be of interest to those in academia and industry.
