  • USACE Vicksburg District, U.S. Geological Survey conduct first-ever airborne geophysical survey

    VICKSBURG, Miss. – An 800-pound dart-shaped instrument is the latest tool to map beneath the surface of levees in a partnership between the U.S. Army Corps of Engineers Vicksburg District and the U.S. Geological Survey. For the first time, a regional geophysical survey will provide a full overview of 800 miles of the Mississippi River mainline levees. Sometimes called a bird, the frequency domain system suspended from a helicopter will use frequency technology similar to LiDAR to differentiate between various soil layers and penetrate about 150 feet under the surface.

  • Corps awards contract for Pigs Eye Lake habitat restoration project

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, in partnership with Minnesota’s Ramsey County awarded a $14.7 million contract to LS Marine, Inc., of St. Paul, Minnesota, June 25, to restore habitat on Pigs Eye Lake, located in upper Pool 2 of the Mississippi River.

  • Memphis District employee proud of Valedictorian daughter

    The Memphis District prides itself on the many achievements made by our employees throughout the year. Not only that, but we consider it especially valuable when employees and their family members experience greatness for their hard work outside of the district. Recently the district had a very special reason to celebrate. Erika Wallace, daughter of M/V Mississippi Machinery Mechanic Ervin Wallace, just graduated from Frederick Douglass Public High School as Valedictorian, with an astounding 4.4 GPA.

  • Corps of Engineers is hosting an open house to gather ideas on managing its dredged material

  • Automated Characterization of Ridge-Swale Patterns Along the Mississippi River

    Abstract: The orientation of constructed levee embankments relative to alluvial swales is a useful measure for identifying regions susceptible to backward erosion piping (BEP). This research was conducted to create an automated, efficient process to classify patterns and orientations of swales within the Lower Mississippi Valley (LMV) to support levee risk assessments. Two machine learning algorithms are used to train the classification models: a convolutional neural network and a U-net. The resulting workflow can identify linear topographic features but is unable to reliably differentiate swales from other features, such as the levee structure and riverbanks. Further tuning of training data or manual identification of regions of interest could yield significantly better results. The workflow also provides an orientation to each linear feature to support subsequent analyses of position relative to levee alignments. While the individual models fall short of immediate applicability, the procedure provides a feasible, automated scheme to assist in swale classification and characterization within mature alluvial valley systems similar to LMV.

  • Forked Deer Hard Points repair construction complete

    "The Memphis District is responsible for maintaining a safe and dependable Mississippi River navigation channel to a minimum of 9 feet deep and 300 feet wide at all times and at all river stages," Project Manager Mark Mazzone said. That's why projects like this, the Mississippi River Channel Improvement Stone Repairs Task Order – Forked Deer Hard Points Repair, are so essential to execute as needed.
