  • From waste to resource

    A new project from the U.S. Army Engineer Research and Development Center (ERDC) is helping meet ambitious goals for beneficially using the material it dredges by exploring how 3D printers can transform the dredged sediment into a building block for ecosystem restoration.

  • Hydraulic engineer learns key element in water infrastructure projects

    Hydraulic engineers specialize in the properties and movement of liquids, namely water. Their job entails making highly educated guesses on how water will interact with infrastructure like dams, bridges, and canals. However, a young U.S. Army Corps of Engineers (USACE) hydraulic engineer’s approach focuses on another—and most important—element tied to their projects, the human element.

  • Wellbot offers innovative solution to cleaning, maintaining relief wells

    Wellbot is an autonomous device that blends the power of UVC-emitting lamps with powerful brushes to address the fouling and corrosion that limits a well’s capacity. It provides districts with a cost-effective alternative without the potential risk from using chemicals, or the need for significant equipment and manpower to deploy.

  • FUNWAVE Model is a Feasible Solution for Vessel Wake Issues

    FUNWAVE, a numerical wave model that simulates ocean surface wave propagation in shallow and intermediate water was developed and updated by ERDC and released in 1998. It can be used to model complex coastal processes, such as tsunami waves, coastal inundation, wave propagation and surf zone-scale optical properties.

  • Memphis District appoints new engineering and construction division chief

    The U.S. Army Corps of Engineers Memphis District promoted Shane Callahan to the engineering and construction division chief role. In this role, he is responsible for flood risk management, engineering and construction, navigation, ecosystem restoration, and water supply projects within the Memphis District's boundaries, including portions of Mississippi, Tennessee, Arkansas, Missouri, Illinois, and Kentucky.

  • Corps of Engineers extends comment period on its draft Wisconsin Line 5 combined decision document

    ST. PAUL, Minn. –The U.S. Army Corps of Engineers, St. Paul District, is extending the public comment period on its draft Wisconsin Line 5 combined decision document to Aug. 30.

  • Jacksonville District set to hold educational webinars and listening sessions about the Integrated Delivery Schedule for Everglades Restoration

    JACKSONVILLE, Fla. – The U.S. Army Corps of Engineers, Jacksonville District invites our partners, stakeholders and the public to join us for two virtual Integrated Delivery Schedule (IDS) educational webinars and stakeholder listening sessions on Friday, Aug. 2, at 3 p.m. and Friday, Aug. 9, 2024, at 3 p.m.

  • ERDC Nurse Ruth Osburn retires after 49 years in healthcare

    Ruth Osburn, who worked as a certified occupational health nurse specialist for the U.S. Army Engineer Research and Development Center’s (ERDC) Health Services Office for 17 years, officially retired Friday, July 12, after a 49-year nursing career.

  • Corps closes Lock and Dam 10 to all navigation to replace miter gates

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, will temporarily close Lock and Dam 10, in Guttenberg, Iowa, to all navigation to replace all four main lock chamber main gates from 7 a.m. to 7 p.m. on the following dates: Aug. 13, 15, 20 and 22.

  • Rectifying and Stabilizing Planet SkySat Video Collects for Bathymetric Inversions from Space

    Abstract: This Coastal and Hydraulics Engineering Technical Note (CHETN) presents the development of a workflow to process Planet SkySat videos collected from space at the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), Field Research Facility (FRF), in Duck, North Carolina, to derive wave kinematics and perform bathymetric inversions. The document summarizes the nine 30–60 s* satellite video collections, demonstrates the accuracy of an automated rectification and stabilization workflow, and applies a new short-dwell version of a common inversion algorithm (cBathy) to demonstrate the utility of short-dwell videos from space providing an initial out-of-the-box assessment of errors for one of the collections, and recommends future avenues of research for improving bathymetric predictions.
