On August 29th, 2005,
Hurricane Katrina hit New
Orleans causing immense destruction in
and around the city.
When the hurricanes
passed over the wetlands, sediments were
churned, and anywhere from one to six inches of new sediment were
the wetlands (Drye). While this could be a very good addition to
soil-deprived wetlands, the hurricanes during 2005 also eroded a lot of
a much faster rate than it had been deteriorating previously.
Katrina alone, the wetlands east of the Mississippi
lost 25% of their land area (Dean, 2006). Though the additional
should promote growth in some areas, there was still a large amount of
done in other locations.
Hurricane Katrina had a severe
and negative impact of Louisiana's
islands. Hurricane Katrina's eyewall passed directly over the Chandeleur Islands, and reduced them an
50% (Louisiana Hurricane Resources). Hurricane Katrina's winds and
also eroded areas of barrier islands much further away from the center
storm. Although barrier islands have some ability to regenerate
hurricane, the regeneration process takes a lot of time, and is often
incomplete. Hurricane Katrina had an especially strong impact on
barrier islands not only because of its size and strength, but also
was the fifth hurricane to impact the Louisiana
coast in eight years (Louisiana Hurricane Resources).
of the few positive results of Hurricane Katrina was that
it sparked further concern for Louisiana’s
disappearing coast. People finally understood the value of
only for the environment, but as a form of protection from
With this newly instated drive, many more projects have been done to
area and to push the coastal reclamation endeavors forward.
