  • 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.

  • Empirical analysis of effects of dike systems on channel morphology of the Lower Mississippi River

  • Memphis District Hurley: Thawed out and ready to dredge

    During most off seasons, maintaining the Hurley takes a few months and a couple of crews to get everything done. This off-season was a bit different, as unexpected weather posed more obstacles than usual. Much of the south, including Memphis, Tennessee, was hit hard with frigid temperatures in mid-February this year. The last time Memphians experienced weather like this was in 1994.  From frozen pipes to no electricity, many people and structures were impacted by the icy weather, including the district’s Dredge Hurley.

  • Corps seeks public comment on service base modernization project

    ST. PAUL, Minn. –The U.S. Army Corps of Engineers, St. Paul District, seeks comments on a draft environmental assessment for proposed upgrades to the Corps’ service base in Fountain City, Wisconsin, that will improve the efficiency of the facility as well and provide a safer working environment for employees.

  • USACE Vicksburg District opens gates of Steele Bayou Control Structure

    The U.S. Army Corps of Engineers (USACE) Vicksburg District opened the gates of the Steele Bayou Control Structure, located approximately 10 miles north of Vicksburg, Mississippi, April 16.

  • Rescue revetment task order awarded

    The Memphis District recently awarded a task order to restore existing revetment and repair over-steepened banks along the Mississippi River in Coahoma County, Mississippi, and Phillips County, Arkansas. A total of $1,344,000 was awarded on the current River Repairs IDIQ (Indefinite Delivery, Indefinite Quantity) Contract to Midwest Construction Company.

  • USACE Vicksburg District hosts Mississippi River Commission, hears public testimony during annual inspection trip

    VICKSBURG, Miss. – The Mississippi River Commission (MRC) will hold a public meeting aboard the Motor Vessel Mississippi April 14 from 1 to 4 p.m. at the Vicksburg City Front. As part of its annual high-water inspection trip, the MRC will hear ideas, concerns and testimonies from stakeholders, local partners and residents.

  • Final levee system project on horizon as MVM completes preliminary projects

    The U.S. Army Corps of Engineers Memphis District, in partnership with the Fulton County Board of Levee Commissioners (FCBLC), is nearing completion of two maintenance projects, the Island 8 Parcel 1 Relief Well Ditch Restoration Project and the Lake No. 9 Collector Ditch Erosion Repair Project, both located along the Mississippi River Mainline Levee south of Hickman, Kentucky. Completing these projects is essential, but what's even more important is what comes after. Once finished, the district will be that much closer to executing the last and final project needed to complete the entire levee system.
