Multibeam Bathymetric Data for the Atchafalaya River

ABSTRACT: Dataset contains multibeam sonar data and bank LIDAR data was for the Atchafalaya River. The survey area was the entire navigation channel of the Atchafalaya River from its junction with the Red River at Old River Outflow Channel to Mile 0 and then from Mile 0 to Mile 126 (1998) just below the confluence with the Intracoastal Waterway. Survey coverage was from the water's edge of the left descending bank to the water's edge of the right descending bank, including under docks and wharves.

PURPOSE: Data was collected to monitor changes in the hydrography of the Atchafalaya river. This dataset is also useful for identifying wrecks and locations of scouring or shoaling. The surface may also be used to extract cross-section geometries to perform bank stability analysis.

COLLECTION DATES: 09/15/2010 to 12/09/2010

SUPPLEMENTAL INFORMATION: Dataset collected under contract number DACW912P8-10-D-0051 by Chutz Surveying, Inc. Time period of data collection estimated from quality control reports. Survey was delivered as a 2x2 foot grid.

FILE NAME: Each file is identified by its river mile. For example "10-151-C-A000.zip" contains the survey for river mile 0, "10-151-C-A001.zip" contains river mile 1, etc.

Hydrographic survey data is subject to change rapidly due to several factors including but not limited to dredging activity and natural shoaling and scouring processes. The U.S. Army Corps of Engineers accepts no responsibility for changes in the hydrographical conditions which develop after the date of publication.
