Lesson Learned?

On August 29, 2005, Hurricane Katrina hit the Gulf Coast. Two and a half years later, have we learned any lessons? Hopefully, the next administration will promote the restoration of the wetlands to help prevent this from happening again.

I just wrote a blog piece, recently, on Katrina. Seemed I found much more primacy than wetlands to report. Though, if this was any kind of factor, I must admit I do not understand it.

Wetlands can create a buffer against the storm surge created during a hurricane. The cypress trees, grasses and other wetland plants create friction against the water that is forced inland from hurricane strength winds. That friction reduces velocities and, therefore, reduces storm surge height. Some scientists believe that a wetlands buffer along the Gulf Coast could reduce a 20 foot storm surge to approximately 5 feet. This reduction in storm surge could greatly reduce the stress on levees during future hurricanes.
