Time Series for the east end of East Island of the Isles Dernieres Aerial Video Survey Program Pontchartrain Institute of Environmental Sciences University of New Orleans Karen A Westphal

The Aerial Video Survey Program has been acquiring photography and video of the northern Gulf of Mexico shoreline since Oblique aerial photography does not produce exact matches due to variations in altitude, camera angle and distance from the shore (and different photographers). Photos that matched well were scaled and aligned to illustrate the landscape changes that have taken place between time periods. Occasionally a pointer or symbol was added to assist with the visual comparison.

Location of East Island, Louisiana East Island is in BICM region “Teche Delta” and BICM segment 36 “East Island”

Relevant Coastal Restoration Projects  Isles Dernieres Restoration East Island. State Project Number: TE-20 Project Priority List (PPL): 01 Federal Sponsor: Environmental Protection Agency (EPA) Project Type: Barrier Island Construction Completion Date: 1999 Description: The project objective is to restore the coastal dunes and wetlands of the Eastern Isles Dernieres. Approximately 3,925,000 cubic yards of sand were dredged from adjacent waters and used to build a retaining dune which was then hydraulically filled to create an elevated marsh platform. Sand fences and vegetation were also installed to stabilize the sand and minimize wind-driven transport.  Isles Dernieres Restoration East Island.
