Description:
Abstract: This report defines hurricane-induced coastal erosion hazards for
sandy beaches along the U.S. Gulf of Mexico coastline. The analysis is based on
a storm-impact scaling model that uses observations of beach morphology
combined with sophisticated hydrodynamic models to predict how the coast will
respond to the direct landfall of category 1-5 hurricanes. Hurricane-induced
water levels, due to both surge and waves, are compared to beach and dune
elevations to determine the probabilities of three types of coastal change:
collision (dune erosion), overwash, and inundation.
As new beach morphology observations and storm predictions become available,
this analysis will be updated to describe how coastal vulnerability to storms
will vary in the future.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The validity or accuracy
of probabilities of coastal change depends largely on the quality of the
morphologic and hydrodynamic parameters. RMS errors for each parameter are
included in each shape file for the user.
Logical_Consistency_Report:
These data are from
different dates with different acquisition systems; however, for most purposes,
the data are comparable across dates and systems.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data have been
