Flood Control Levees

Submitted by Anonymous (not verified) on

Flood protection in south Louisiana is largely dependent on earthen levees, and following Hurricane Katrina no infrastructure has received more scrutiny than the State's levee system. The USGS is working with local levee districts to map and monitor non-Federal levees using airborne and terrestrial lidar surveys. The purpose of the study is to demonstrate the capability to collect high-resolution, high-accuracy elevation data to benefit local levee districts in south Louisiana as well as the coastal monitoring and restoration community.  The USGS is developing a suite of analytical tools for rapidly analyzing lidar-derived levee metrics including levee crest elevation, crown width, levee volume.  Future lidar data acquisitions are planned to examine the utility of Lidar to monitor changes in levee elevation and volume over time.
