  • USACE Jacksonville announces changes to Brevard Mid-Reach, South Reach beach renourishment

    USACE Jacksonville District announces changes to the 2024 Brevard County beach renourishment project due to delays in equipment availability.
  • Corps of Engineers Begins Dredging Muskegon Harbor, First of Season

    The U.S. Army Corps of Engineers, Detroit District began dredging today, March 8, in Muskegon Harbor to remove about 133,000 cubic yards of sediment from the federal navigation channel. The project marks the start of the 2024 Detroit District dredging season on the Western Michigan shoreline of Lake Michigan to maintain Great Lakes navigation for commercial shipping to harbors along Western Michigan.
  • Hurdles to Beneficial Use of Dredged Material: Root Cause Analysis

    Purpose: This technical note (TN) summarizes high points of an internal review of US Army Corps of Engineers (USACE) dredging and dredged material management practices, specifically beneficial use of dredged material (BUDM), that USACE manages from various navigation channels and ports around the nation.

  • Hydraulic Sorting of Dredged Sediment in a Pipeline: An Evaluation of the Sediment Distribution Pipe

    Abstract: The US Army Corps of Engineers (USACE) recently established a goal to beneficially use 70% of material dredged from the nation’s navigable waterways by the year 2030. Most of the sediments dredged by the USACE are heterogeneous mixtures of mud and sand, which can limit beneficial use of dredged material (BUDM) applications. Innovative technologies that can sort material during the dredging process are needed to help increase BUDM practices. This investigation sought to evaluate the ability of a sediment distribution pipe (SDP) to sort particles during transport in a pipeline. Field demonstrations were conducted during dredged material placements at Sturgeon Island, New Jersey. Velocity within the pipeline was found to be inadequate for efficient hydraulic sorting of fines (<75 μm) and produced inconclusive results. Small scale laboratory SDP experiments found that effluent from the SDP holes had an altered sediment texture compared to the initial slurry and that hydraulic sorting was occurring within the pipeline. However, outflow from the SDP holes was inconsistent, and typically >90% of the sediment mass was discharged out the end of the pipeline. Sorting efficiency of the SDP could not be accurately assessed in the current experimental configuration.
  • ERDC researchers assess time-of-year restrictions for James River dredging

    Researchers at the U.S. Army Engineer Research and Development Center’s (ERDC) Environmental Laboratory (EL) are conducting field studies along the lower James River in Virginia to assess the environmental impacts of dredging and if they continue to justify the existing time-of-year restrictions (TOYR) for dredging in the area.
