Military
GeoTek
uses
a
suite
of
non
intrusive,
surface-based
geophysical
sensors
to
estimate
levee
and
levee
foundation
soil
properties.
Geophysical
sensors
provide
continuous
soil
data
along
survey
paths.
In
some
geologic
settings,
data
can
be
collected
to
depths
in
excess
of
50
meters.
ERDC
geophysicists
have
conducted
surveys
on
several
levee
systems
using
combinations
of
ground
penetrating
radar,
electromagnetic
(EM)
induction,
dc
electrical
resistivity,
capacitively
coupled
resistivity
(CCR),
and
magnetic
and
seismic
methods
to
rapidly
interrogate
subsurface
conditions.
Geophysical
surveys
can
also
be
used
in
locating
buried
utilities
or
structures within or beneath levees, as these can provide a seepage path during flooding periods.
Geotechnical
Engineering
involves
soil
and
its
properties
relevant
to
groundwater
flow,
bearing
capacity
for
foundations,
settlement
and
compaction,
slope
stability,
tunneling
and
mining,
and
a
variety
of
other
issues
associated with activities on or below the ground surface.
