• Gavins Point Dam releases reduced to winter release rate

    The U.S. Army Corps of Engineers began reducing the Gavins Point releases to the winter release rate on Nov. 23 with the navigation flow support season ending on Dec. 1 at St. Louis. “Releases from Gavins Point Dam are being reduced to the 12,000 cubic feet per second winter release rate by mid-December,” said John Remus, Chief of the Missouri River Water Management Division. “We will closely monitor river conditions, and releases will be adjusted to the extent practical to lessen the impacts of river ice formation on stages in the lower river.” Releases were at 32,000 cfs prior to the reductions.
  • U.S. Army Fort Wingate Depot Activity announces public interest survey for participation in re-activating a Restoration Advisory Board

    The U.S. Army Fort Wingate Depot Activity (FWDA) is conducting a survey to determine if there is enough public interest to re-activate the FWDA Restoration Advisory Board (RAB). The RAB provides a public venue for citizens to provide input on the decisions that are made by the Army to clean up the installation and meet the permit requirements.

  • ERDC Celebrates Milestone with GridStar® Flow Battery Installation at Fort Carson

    The U.S. Army Engineer Research and Development Center's (ERDC) Operational Energy (OE) team is celebrating the construction and installation of the GridStar® Flow system, a redox flow battery solution designed for long-duration, large-capacity energy storage applications. The flow system is installed at Fort Carson, Colorado, and ERDC has led the technical evaluation and project management since 2022.
  • USACE Emergency response missions, different but the same

    When a disaster happens, one can usually count on seeing the U.S. Army Corps of Engineers (USACE) on the scene, assisting residents to get back to normalcy as quickly and safely as possible. From supporting relief efforts after the 9/11 terrorist attacks to supporting the current Hurricane Helene mission in the agency’s Savannah District, USACE’s role in a disaster remains consistent as it adapts to ever-changing demands of each mission.
  • Establishing a Workflow for Near-Seamless Digital Elevation Model Creation in the Great Lakes for ADCIRC Modeling

    Abstract: This report introduces a workflow to create near-seamless, regional digital elevation models (DEMs) for use in coupled Advanced Circulation and Simulating Waves Nearshore modeling. The workflow is based in Esri ArcGIS Pro, leveraging the Mosaic Dataset architecture to organize and mosaic survey data sets into near-seamless DEMs. This workflow includes data collection and preprocessing, creation of source and derived mosaic data sets, manual editing of the data set seamlines, the creation of spatial metadata products, and quality assurance and control measures. These steps were implemented for each Great Lake to provide a high-resolution, near-seamless DEM product for modelers. The workflow may also have utility for other regional-scale investigations.
  • Safety First: USACE's number one priority during disaster response

    Before its employees set foot on a disaster response mission, the U.S. Army Corps of Engineers (USACE) has already established a safety framework emphasizing its number one principle: safety, the number one priority of USACE.
  • Comparison of Run-Up Models with Field Data

    Abstract: Run-up predictions are inherently uncertain, owing to ambiguities in phase-averaged models and inherent complexities of surf and swash-zone hydrodynamics. As a result, different approaches, ranging from simple algebraic expressions to computationally intensive phase-resolving models, have been used in attempt to capture the most relevant run-up processes. Studies quantifiably comparing these methods in terms of physical accuracy and computational speed are needed as new observation technologies and models become available. The current study tests the capability of the new swash formulation of the Coastal Modeling System (CMS) to predict 1D run-up statistics (R2%) collected during an energetic 3 week period on sandy dune-backed beach in Duck, North Carolina. The accuracy and speed of the debut CMS swash formulation is compared with one algebraic model and three other numerical models. Of the four tested numerical models, the CSHORE model computed the results fastest, and the CMS model results had the greatest accuracy. All four numerical models, including XBeach in surfbeat and nonhydrostatic modes, yielded half the error of the algebraic model tested. These findings present an encouraging advancement for phase-averaged coastal models, a critical step towards rapid prediction for near-time deterministic or long-term stochastic guidance.
