Seasonal and storm-induced changes in mean shoreline position for 18 months
of SWASH surveys along 28 km of Cape Cod's outer
coast.

On October 2-7, Jeff List, Barry Irwin, and Kathy Konicki (WHFC)
conducted SWASH surveys of shoreline position along 130 km of
the new North Carolina's Outer Banks as part of the North Carolina
coastal-erosion project. These surveys re-established the Corolla
to Oregon Inlet section studied intensively during the 1997
Sandyduck experiment and established Oregon Inlet to Hatteras
Point as a new coastal reach for SWASH studies of the shoreline
response to storms.
Over the coming winter season, the SWASH team will be on standby
for repeated surveys of shoreline changes in response to Nor'easter
storms in the Outer Banks. Over the next several weeks, Abby
Sallenger (St. Pete) will also be focusing on storm impacts along
this coast, working with NASA and NOAA to conduct regional LIDAR
surveys of three-dimensional topography. The LIDAR and SWASH surveys
will characterize the full beach and dune response. This work is
also being done as a component of the new North Carolina
coastal-erosion project.
The Outer Banks measurements represent one of three field areas
that will be surveyed by the SWASH system this winter, promising
a very busy winter for the SWASH team if it turns out to be a
stormy season. Measurements along the outer coast of Cape Cod
are continuing, with over 1.5 years of bi-weekly data beginning
to reveal an interesting picture of the annual cycles of beach
changes. In the next several weeks the team will also establish
a new SWASH survey site on Fire Island, Long Island, with the hope
of capturing the impact of at least one storm this winter. These
measurements will be examined in the context of longer term
measurements of shoreline change by Jim Allen (USGS/BRD) and
results of ongoing wave-modeling studies in this area conducted
by Courtney Harris (WHFC).
