Hurricane
Katrina made landfall on the eastern coastline of Louisiana on August
29, 2005; Hurricane Rita made landfall on the western coastline of Louisiana
on September 24, 2005. Comparison of Landsat Thematic Mapper (TM) satellite
imagery acquired before and after the landfalls of Katrina and Rita and
classified to identify land and water demonstrated that water area increased
by 217 mi2 (562 km2) in coastal Louisiana as a result of the storms. These new water areas represent
land losses caused by direct removal of wetlands. They also indicate
transitory changes in water area caused by remnant flooding, removal
of aquatic vegetation, scouring of marsh vegetation, and water-level
variation attributed to normal tidal and meteorological variation between
satellite images. Permanent land losses cannot be estimated until several
growing seasons have passed and the transitory impacts of the hurricanes
are minimized. The purpose of this study was to provide preliminary information
on water area changes in coastal Louisiana acquired shortly after the
landfalls of both hurricanes (detectable with Landsat TM imagery) and
to serve as a regional baseline for monitoring posthurricane wetland
recovery.
