Geotechnical and
GeoHazards
Systems (GHS)
The
Geotechnical and GeoHazards Systems (GHS) program seeks to advance the fundamental
engineering and related knowledge for geostructures (foundations, slopes,
excavations, soil and rock improvement technologies, and reinforcement systems);
geohazards mitigation; constitutive modeling and verification; remediation
and containment of geoenvironmental contamination; transferability of laboratory
results to field scale; and non-destructive and in situ evaluation. GHS
support is given for research that will increase geotechnical and geohazards
knowledge necessary to mitigate the impacts of natural and technological
hazards on both the constructed and the natural environment. A broad
spectrum of research is supported, including the use of data from laboratory
and field experiments to verify design procedures and methodologies, simulation
of phenomena, collection of data from catastrophic events, including rapid-response
reconnaissance inspections.
Geomechanics
and Geotechnical Systems (GGS)
The
research portfolio for the Geomechanics and Geotechnical Systems (GGS)
program element includes projects on geomechanics, geotechnical engineering,
problem soils, weak rocks, rock mechanics and rock engineering, and mining
engineering. Support is given for research that will increase geotechnical
knowledge for foundations, slopes, excavations and other geostructures, including
soil and rock improvement technologies and reinforcement systems; constitutive
modeling and verification in geomechanics; transferability of laboratory
results to field scale; and non-destructive, remote and in situ evaluation
of soil and rock properties.
Geoenvironmental
Engineering and GeoHazards Mitigation (GEH)
The
research portfolio for the Geoenvironmental Engineering and GeoHazards Mitigation (GEH)
program element includes projects on geoenvironmental engineering, including
physical, chemical, thermal and biological processes that affect the properties
of geologic materials; contaminant transport and hydraulic properties of
geologic materials involved in surface and subsurface flow; and construction
for remediation and containment of geoenvironmental contamination. The
GEH program also supports research in geological engineering and engineering
geology, geotechnical earthquake engineering and strong ground motions, piping
(particle erosion, transport, and deposition), scouring, tsunamis (both earthquake
and non-earthquake generated), landslides and debris flows, forest fires,
droughts and floods.
