Hydrologic Atlases Showing Areas Flooded by Hurricane Camille Tides of August 18, 1969, Along the Mississippi Gulf Coast |
|
The approximate areas flooded by Hurricane Camille tides of August 18, 1969, along the Mississippi Gulf Coast are shown in a series of 14 hydrologic atlases. The area covered by the series of atlases extends from Bayou La Batre, Alabama, westward along the gulf coast through Mississippi to the mouth of the West Pearl River, a distance of about 90 miles. On November 10, 1969, 12 weeks after Hurricane Camille made landfall, the U.S. Geological Survey made public distribution of these atlases. The atlases are the culmination of effort that began soon after the hurricane made landfall in the Waveland and Bay St. Louis, Mississippi, area late during the night of August 17, 1969. The U.S. Geological Survey recognized the need to get the data to the public as soon as possible because any realistic and effective settlement of insurance claims and plans for rebuilding in the devastated area would require the delineation of the land area flooded. The U.S. Geological Survey was able to produce in 3 months a series of atlases that would have normally required one to two years to complete. The U.S. Geological Survey recently used the data shown on these atlases as a guide to determine locations for flagging and surveying storm-tide flood elevations caused by Hurricane Georges, which made landfall on September 28, 1998, in the Ocean Springs and Biloxi, Mississippi, area. Hurricane Georges was considered a strong Category 2 hurricane, and Hurricane Camille was considered a category 5 hurricane. The maximum storm-tide elevation surveyed for Hurricane Georges was 11.0 feet above sea level near Pascagoula; at the same location, the storm-tide elevation for Hurricane Camille was 12.7 feet above sea level. The maximum elevation for Hurricane Camille was 24.2 feet above sea level at Pass Christian; at the same location, the elevation for Hurricane Georges was 7.0 feet above sea level. These atlases are provided in digital form as part of a cooperative program between the U.S. Geological Survey and the Mississippi Department of Transportation. The atlases are provided via the internet, so that more people can become aware of their existence. The highly compressed image file (SID) for each atlas will need to be downloaded to your system for viewing. Downloading speed will be dependent on your modem speed and internet traffic.
