Topographic and Bathymetric Surveys: Bogue Inlet
Relocation

Geodynamics was contracted
by Coastal Planning and Engineering to perform
topographic and bathymetric surveys at Bogue
Inlet, North Carolina. RTK-GPS was used to collect
topographic beach data, morphologic break-points
between the marsh-water interface and provide
decimeter level positioning and tidal information
for singlebeam bathymetric mapping of the channels
within the inlet complex. In addition, high-res
digital photography was georeferenced to the
morphologic break-points.

The
relocation project is being proposed to move
the main ebb channel in Bogue Inlet to a
more central location between the west end
of Bogue Banks and the east end of Bear Island
(Hammocks Beach State Park).

| The
relocation of the main ebb channel to a central location
would restore the channel to a position it occupied
in the late 1970s and eliminate the erosive impact
of tidal currents on the east shoulder of the inlet.
A portion of the material removed to relocate the
main ebb channel would be used to close the existing
channel with the balance of the material used to
nourish the shoreline on the west end of the Town
of Emerald Isle (USACE, 2003) |
