For the InstructorThese student materials complement the Coastal Processes, Hazards and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Coastal Louisiana is an example of a very low-profile coastal area characterized by relatively newly deposited delta sediment (less than 10 thousand years) of the Mississippi River delta. Land loss has been ongoing at a rapid pace over the past century, peaking in the late 20th century and is currently occurring at a rate of approximately 10 – 20 square miles per year. The communities in coastal Louisiana are all at risk to storm surge inundation, to varying degrees. We have already looked at New Orleans in detail, and seen that it has a system of flood defenses recently upgraded after Hurricane Katrina. Many smaller communities that are located close to the Gulf of Mexico have no protection from federally funded flood protection. Many have levees built and maintained at a parish level. New federally-funded hurricane protection levees such as the Morganza to the Gulf levee system are planned to protect towns such as Houma and Thibodaux, but some small communities such as Cocodrie and Isle De Jean Charles will not be within the footprint of this levee. It is not feasible in terms of available funding and engineering options to protect some communities. This presents a dilemma for many communities.
