  • ERDC researcher’s detective work helps ship channel improvement project stay on track

    A construction effort as massive as the Houston Ship Channel Expansion Improvement Project — designed to accommodate the wider and deeper ships now carrying goods back and forth between Asia and the U.S. — has many regulatory requirements that need to be met.

  • Army Corps, State to host public meeting on Ocean City Inlet projects

    The U.S. Army Corps of Engineers, Baltimore District (USACE), in coordination with the Maryland Department of Natural Resources (DNR) and Worcester County, is hosting a hybrid public meeting Aug. 17, 2021, at the Worcester County Library – Berlin Branch at 13 Harrison Ave., from 7 – 8:30 p.m. This public meeting provides an opportunity to discuss two concurrent efforts: a navigation improvement project to address sediment accumulation in the Ocean City Inlet and a study on the scour hole near Homer Gudelsky Park.

  • Corps plans Depoe Bay dredging, after environmental assessment

    The U.S. Army Corps of Engineers will begin dredging Depoe Bay, Ore. to remove 2,000 cubic yards of material between September 13 and the end of the month. The work will take place for seven to 14 days and is an effort, with the City of Depoe Bay, to clean out the sediment catch basin.

  • An Assessment of Long-Term, Multipurpose Ecosystem Functions and Engineering Benefits Derived from Historical Dredged Sediment Beneficial Use Projects

    Abstract: The beneficial use of dredged materials improves environmental outcomes while maximizing navigation benefits and minimizing costs, in accordance with the principles of the Engineering With Nature® (EWN) initiative. Yet, few studies document the long-term benefits of innovative dredged material management strategies or conduct comprehensive life-cycle analysis because of a combination of (1) short monitoring time frames and (2) the paucity of constructed projects that have reached ecological maturity. In response, we conducted an ecological functional and engineering benefit assessment of six historic (>40 years old) dredged material–supported habitat improvement projects where initial postconstruction beneficial use monitoring data was available. Conditions at natural reference locations were also documented to facilitate a comparison between natural and engineered landscape features. Results indicate the projects examined provide valuable habitat for a variety of species in addition to yielding a number of engineering (for example, shoreline protection) and other (for example, carbon storage) benefits. Our findings also suggest establishment of ecological success criteria should not overemphasize replicating reference conditions but remain focused on achieving specific ecological functions (that is, habitat and biogeochemical cycling) and engineering benefits (that is, storm surge reduction, navigation channel maintenance) achievable through project design and operational management.

  • Corps set to move dredged material, urges caution near work site

    The U.S. Army Corps of Engineers, St. Paul District, is scheduled to begin moving approximately 50,000 cubic yards of river sand, or dredged material, from the Dakota Island Placement Site, near Dakota, Minnesota, to the Trempealeau, Wisconsin, Placement Site, which is about 8 miles away.

  • Metrics of Success for Nearshore Nourishment Projects Constructed with Dredged Sediment

    Purpose: This Regional Sediment Management Technical Note (RSM TN) provides practical metrics of success for nearshore nourishment projects constructed with dredged sediment. Clearly defined goals and performance metrics for projects will set clear expectations and will lead to long-term project support from local stakeholders and the public.

  • ERDC science helps USACE districts ease time-of-year dredging restrictions

    It was when he was a graduate student at Virginia Commonwealth University that Dr. Matt Balazik, a research ecologist with the U.S. Army Engineer Research and Development Center’s Environmental Laboratory, began intensely studying Atlantic sturgeon, its populations now listed as either threatened or endangered under the Endangered Species Act.

  • Army Corps, partners conducting monitoring in New Jersey estuaries and back bay marshes

    The U.S. Army Corps of Engineers and partners are conducting monitoring in multiple locations along the marshes and in the waterways behind Seven Mile Island in Cape May County, N.J.

  • Corps, Port of Hueneme celebrate completion of harbor-deepening project

    Representatives with the U.S. Army Corps of Engineers Los Angeles District, Port of Hueneme and the U.S. Navy, among other agencies, celebrated June 28 as officials cut the ribbon signifying the completion of the Port of Hueneme’s port-deepening project.

  • ERDC mourns loss of dredging industry expert

    The dredging industry has suffered a great loss with the recent death of Timothy L. Welp, a research hydraulic engineer with the U.S. Army Engineer Research and Development Center (ERDC).
