project is funded by the National Aeronautics and Space Administration's
(NASA's) Solid Earth and Natural Hazards Program. The goal is to
apply advanced terrain mapping technology to improve our understanding
of storm hazards and erosion along sandy barrier island coasts.
The Bureau is using its airborne topographic lidar instrument to
acquire detailed terrain models of beaches and dunes along the southeast
Texas coast. With these models we can accurately track the change
in position of the shoreline and develop sediment-volume budgets
for the beach/dune system. Spatial variation in the sand volume
and elevation and shape of the beach/dune system is a primary control
on the amount of damage to landward structures during storms. This
project is mapping these variations and developing new parameters
to describe them.
