  • U.S. Army Corps of Engineers Deploys the Murden for Dredging Operations in Lake Montauk

    NEW YORK – The U.S. Army Corps of Engineers (USACE), New York District, is deploying the Wilmington District, shallow draft dredge, Murden, to Lake Montauk to conduct vital dredging operations aimed at maintaining safe and efficient navigation for commercial and recreational vessels.

  • Jacksonville District begins dredging of Palm Beach Harbor

    U.S. Army Corps of Engineers (USACE), Jacksonville District, will begin maintenance dredging of the Palm Beach Harbor, Palm Beach County, Florida, on or around March 3, 2025.

  • Jacksonville District issues scoping letter for Fort Myers Beach Harbor

    (Feb. 13, 2025) - The U.S. Army Corps of Engineers, Jacksonville District (USACE), seeks public comments, views and information regarding the preparation of a supplemental National Environmental Policy Act (NEPA) analysis evaluating alternative placement options for operation and maintenance dredged material from the Fort Myers Beach Harbor (FMBH) Federal Navigation Channel in Lee County, Florida.

  • Notes on Bedload Sediment Collector Deployment: Eau Claire River, Wisconsin

    Purpose: A bedload sediment collector field deployment was conducted during low flow conditions from August 2023 to September 2023 on the Eau Claire River, Wisconsin, to assess the operation and performance of a 12 ft bedload sediment collector (BSC). This initial deployment of the technology served to familiarize the research team with the new 12 ft BSC system in preparation for its potential deployment during high flow conditions and at other locations. The insights from this study are intended to identify opportunities to use this technology, particularly in the Upper Mississippi River navigation system.

  • 2 For 1: Dredging, Sand Placement is Double Benefit for Long Island’s South Shore, Barrier Beaches

    The U.S. Army Corps of Engineers, New York District, has commenced essential maintenance dredging for the Fire Island Inlet and Shores Westerly to Jones Inlet New York Beach Erosion Control and Navigation Project. This critical work, awarded to Norfolk Dredging Company for nearly $37 million, began in November and is expected to continue until early spring 2025.

  • Acoustic Camera Systems and Methods for Large-Scale Flow Analysis in Turbid Field Environments receives patent

    The Acoustic Camera Systems and Methods for Large-Scale Flow Analysis in Turbid Field Environments is a breakthrough technology developed at the U.S. Army Engineer Research and Development Center (ERDC) to revolutionize how researchers and engineers monitor fluid motion in turbid waters where traditional optical methods face limitations due to visibility.

  • Modular Bathymetry Systems and Methods: A Revolutionary Approach to Underwater Mapping

    The recently patented Modular Bathymetry Systems and Methods, developed by researchers at the U.S. Army Engineer Research and Development Center (ERDC), offers a groundbreaking solution for underwater terrain mapping.

  • Upper Mississippi River Main Channel Sediment Placement: Purpose, Practice, Effects, and Recommendations

    Abstract: Dredged-sediment management in the Upper Mississippi River and Illinois Waterway is constrained by environmental factors and regulations that limit where sediment can be placed. Regulations regarding in-water sediment placement are not consistent among states. In-water placement should be promoted because it keeps sediment in the system and reduces costs for managing sediment dredged from the river. Studies investigating the environmental effects of in-water placement generally conclude that sand-on-sand placement has minimal effect on aquatic resources in the dynamic riverine environment. This report discusses in-water sediment management techniques, including flow- and sediment-regulating structures (i.e., dikes and wing dams) and a bed-load sediment collector by-pass system.

  • Project partners celebrate forthcoming beach renourishment completion at San Clemente press conference

    The U.S. Army Corps of Engineers Los Angeles District took part in an Oct. 31 beachside press conference as it nears completion of its much-anticipated beach renourishment project in San Clemente, California.

  • Corps of Engineers, Navy collaborate in experimental dredging for U.P. harbor

    The U.S. Army Corps of Engineers, Detroit District and Engineer Research and Development Center in partnership with the U.S. Navy removed over 25,000 cubic yards of material from Little Lake Harbor in the Upper Peninsula of Michigan this fall.   Little Lake Harbor, designated as a harbor of refuge, requires annual maintenance dredging. The harbor had severe shoaling and emergency dredging was completed in 2023.   This year, a unique opportunity with the Corps of Engineers Engineer Research and Development Center (ERDC) and the U.S. Navy arose.   “We were working with ERDC on redesigning the federal structures at Little Lake Harbor and ERDC was working with the Navy on experimental training,” said Soo Project Office, St. Marys River Section Chief Justin Proulx. “ERDC brought the two of us together to train the Navy on opening harbors and dredging the Detroit District’s shoaled in Little Lake Harbor.”
