Services include:

• Riverine and coastal engineering

After natural disasters, the U.S. Army Corps of Engineers (USACE) often looks to its engineering team members for support. Under contract for riverine and coastal engineering services with the USACE’s New Orleans District, Baker has performed multiple task orders for the USACE’s water resources program and its post-Katrina recovery activities.

Specific support activities include the following:

Evaluation and Analysis of Coastal Levees and Floodwalls for Hurricane Protection Projects.  Evaluated levees, floodwalls, and closure structures.  Performed risk and uncertainty analyses to determine assurance levels for levee and floodwall heights.  Also conducted wave height and levee analysis for Plaquemines Parish to determine appropriate levee heights as part of rebuilding efforts.

Calcasieu Lock Feasibility Study.  Provided modeling to determine reduction in flooding attributable to the use of Calcasieu Lock for drainage of the lower Mermentau Basin, near Lake Charles, Louisiana.

On-site H&H Support to Floodplain Management Services Program (FPMS). Developed interior drainage, networked unsteady HEC-RAS models for new hurricane protection systems for Donaldsonville and Alexandria, Louisiana.

Mississippi River Sediment Analysis. Analyzed 40 years of sediment and discharge data for the Mississippi River and the Old River Outflow Channel and developed discharge-sediment concentration rating curves, discharge-sediment load rating curves, and annual and decadal total load.
