Hurricanes are highly destructive storms that cause destruction to not only human property but also the environment of coastal regions. The most common damages include raising sea levels and shoreline erosion. Several studies have revealed some more of hurricanes' immense power. For example, Hurricane Andrew completely wiped out the vegetation in the northern part of the Florida Keys and defoliated almost all of the mangrove trees. Andrew also stripped sand away from about seventy percent of the barrier islands exposing the bare marshlands. Another severe problem caused by hurricanes is erosion of the coast that is having an especially heavy impact on Louisiana. Currently, Louisiana is losing its barrier islands at a rate of 40 km per year. If this carries on, all of Louisiana�s wetlands will be lost in a few decades. In order to plan to reduce environmental damage, we must first understand the aspects of geological processes that cause erosion and environmental change. Data collected from the Louisiana Barrier Island Erosion Study is now being used by parish planners and engineers involved in the restoration project. |
