Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
Information on video and still photography used to supplement laser altimetry measurements of the coast. The photography is used for recognizing geomorphic and cultural features impacted by storms. Links to photo collections of hurricanes and El Nino.
Airborne scanning laser surveys (LIDAR) are used to obtaining data to investigate the magnitude and causes of coastal changes that occur during severe storms. Links to examples of coastal mapping during specific hurricanes.
Description of three types of severe coastal storm impacts: hurricane impacts on the southeast U.S., extra-tropical storm impacts on the U.S. west coast during El-Nino winters, and 'northeaster' impacts on the U.S. east coast.
Characteristics of recent tsunami deposits, with the knowledge we have about the events that caused them, give us ways to recognize ancient deposits of this type and infer characteristics of those ancient tsunamis as well.
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.
