Simulating Wave Heights and DirectionsAlong the Coast
and storm surges, have often produced results where
the simulation of coastal flooding was below the actual
observed coastal flooding.
There is a lack of raw data consisting of wave height
measurements and wave directional data offshore or
in the Barrow coastal region.
The Research Problems
The Naval Arctic Research Lab (NARL)(Approximately 1.5 miles north of Barrow)
October 1963

October 1963 Flood Extent with 12 and 16 Foot Contours for Barrow, Alaska
Flood map constructed by Leanne Lestak, William F. Manley, and James Maslanik, August 2003. The October 1963 flood extent was mapped by Hume and Schaulk, 1967.
ChukchiSea
The purpose of this project is the use of the
Simulation of Waves Near shore (SWAN) model to
simulate wave heights and directions offshore and
in
the Barrow coastal region.
Incorporating the results from from the SWAN
model
with a storm surge model for Barrow, will allow a
total
flood height to be simulated and compared with
past, observed coastal flooding.
Purpose
Bathymetry map of the Barrow coastal region

Barrow
ChukchiSea
BeaufortSea
Bathymetry of the Barrow Coastal Region
Bathymetry of the Barrow coastal region compiled with data from NOAA and NGDC
Daily and average monthly sea ice concentration data from NSIDC
Daily average wind speeds and directions for 11 historical storms from the Barrow NWS office
Hourly wind speeds and directions for the 29 July 2003 storm from the Barrow NWS office
The computational grid will represent an area 390 by 390 km over the Alaska North Slope coastline and the Chukchi/Beaufort Seas.

The Simulation of Waves Near shore Model
SWAN is a wave simulation model specificallydesigned to simulate wave heights for shallow coastal areas.
Input data for SWAN includes:
Wind direction and speed
Location and shape of the shoreline
Bathymetry of the coastal seafloor
