Sediment berm along the northern Chandeleur Islands, Louisiana

Sediment berm placement in the shoreface of northern Chandeleur Islands, Louisiana

(looking north). This berm was placed in 2010 during the Deepwater Horizon oil spill to prevent oil from reaching the island and the mainland of Louisiana in this area of the coast. The sediment deposited along the shoreline was dredged from a borrow pit north of berm placement on a

Total Water Level and Coastal Change Forecast Expansion, 2020

The Total Water Level and Coastal Change Forecast has continually expanded since real-time forecasts began in 2015. In 2020, new regions of the Gulf and South Atlantic coasts were added to the forecast and officially approved for use in National Weather Service Forecasts. The Total Water Levels and Coastal Change (TWL-CC) Forecast Viewer is a web-based tool that visualizes

Coastal Change Hazards Portal for Hurricane Laura

This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura.  The model accounts for sandy beaches and barrier islands and does not include marshes, forested or sea
