Geologic studies at the FRF have included surface sediment texture, box and vibracoring, subbottom profiling, and side-scan sonar mapping
Oregon Inlet in North Carolina, the only inlet along a 170 km stretch of coast, supports an active commercial fishing and recreational boating industry. Severe erosion, because of the ongoing migration of OI, resulted in NC constructing a terminal groin in 1990 to prevent the highway from being cut off.
SUPERDUCK Sep-Oct 1986
This experiment involved people from seven
agencies, ten universities, and three foreign countries. Thirty different studies were
conducted during this two-phase experiment including detailed measurements of the
alongshore current in the surf zone. One major discovery was of shear waves, a wave like
surf zone instability which can account for a significant percentage of the energy in the surf
zone, especially during storms.
Similar to DUCK82, but more frequent surveys and a
permanent array of surf zone instrumentation were used to measure the processes.
DUCK82 October 1982
A multi-agency nearshore processes experiment was conducted to
measure the nearshore morphological response to storm-induced waves and currents. This
experiment provided some of the first ever quantitative data on the rapid bottom changes that
occur in the surf zone during storms.

Beneficial use of dredged material is a priority for the USACE. Placement of dredged material as nearshore berms could provide for shorline stability and greatly reduce the cost...
