Geological and geotechnical engineering: Expert Reports

The division produces 60-70 reports per year. These reports are unique, authoritative expert evaluations. Each report is produced by a committee of experts selected by the Academy to address a particular statement of task and is subject to a rigorous, independent peer review. The experts who volunteer their time participating on study committees are vetted to make sure that the committee has the range of expertise needed to address the task, that they have a balance of perspectives, and to identify and eliminate members with conflicts of interest. All reports undergo a rigorous, independent peer review to assure that the statement of task has been addressed, that conclusions are adequately supported, and that all important issues raised by the reviewers are addressed. Thus, while the reports represent views of the committee, they also are endorsed by the Academy.

State of the Art and Practice in the Assessment of Earthquake-Induced Soil Liquefaction and Its Consequences (2016)

Earthquake-induced soil liquefaction is a leading cause of earthquake damage worldwide. Studies often describe liquefaction as the phenomena of seismic generation of excess porewater* pressures, which then soften granular soils. Many regions in the United States have been witness to liquefaction and its consequences, such as the inability of soils to support the foundations of buildings and other infrastructure. Past damage and destructio... More >>

Characterization, Modeling, Monitoring, and Remediation of Fractured Rock (2015)

Characterizing and modeling fluid flow through fractured rock is vital to limiting the spread of chemical contaminants through rock features; for understanding where reservoirs of petroleum, water, or geothermal resources may form; and for engineering stable and resilient underground infrastructure. Over the past twenty years there have been significant advances in abilities to model and characterize these pathways, but significant challenge... More >>

Underground Engineering for Sustainable Urban Development (2013)

Humans have long relied on underground space for the placement of physical structures that allow our cities and developed areas to function safely. These include building foundations, underground utilities (e.g., power, gas, communications, waste management), transportation (e.g., roads and highways, subways, freight and passenger rail) and their supporting facilities. However, underground infrastructure is rarely engineered in coordination wit... More >>

Dam and Levee Safety and Community Resilience: A Vision for Future Practice (2012)

Although advances in engineering can reduce the risk of dam and levee failure, some failures will still occur. Such events cause impacts on social and physical infrastructure that extend far beyond the flood zone. Broadening dam and levee safety programs to consider community- and regional-level priorities in decision making can help reduce the risk of, and increase community resilience to, potential dam and levee failures. Collaboration betwee... More >>

Induced Seismicity Potential in Energy Technologies (2012)

Report in Brief >> In the past several years, some energy technologies that inject or extract fluid from the Earth, such as oil and gas development and geothermal energy development, have been found or suspected to cause seismic events, drawing heightened public attention. Although only a very small fraction of injection and extraction activities among the hundreds of thousands of energy development sites in the United States have induce... More >>
