  • Buffalo River Habitat Restoration Completed at Katherine Street

    The U.S. Army Corps of Engineers, Buffalo District, in partnership with the U.S. Environmental Protection Agency, has completed closeout of the habitat restoration along the Buffalo River near Katherine Street. The $2.7 million project, funded by the EPA’s Great Lakes Restoration Initiative, was the final habitat restoration project required to complete management actions before delisting the Buffalo River Area of Concern.

  • Framework Development for Rapid Assessment and Economic Valuation of Feral Swine Damage to Wetland Terrain: A Pilot Study at US Army Corps of Engineers–Somerville Lake, Texas

    Abstract: The increased spread and presence of feral swine on sensitive natural resources landscapes like wetlands has become a considerable concern on lands managed by the US Army Corps of Engineers. In August 2021 a pilot study was carried out at Somerville Lake, Texas, as the first step in a three-year research plan to develop an ecological-economic framework for feral swine damage assessments (FSDA) and valuation. The study sought to quantify and value soil disturbance caused by feral swine trampling, rooting, and wallowing on wetland soils. The primary objective—to develop and test a rapid FSDA prototype—was achieved and represents an important first step to creating a quick and user-friendly damage-assessment framework that also estimates the economic value of the damage observed. With continued testing and development, this rapid FSDA protocol will be of use to all who manage feral swine impacts on landscapes with wetland ecosystems, and findings from this information will be of use for scientifically informed cost-benefit analysis and management decision-making.

  • Considerations for Integrating Ecological and Hydrogeomorphic Models: Developing a Comprehensive Marsh Vegetation Model

    PURPOSE: Predictive models for salt marsh management require a systems perspective that recognizes the dynamic interactions between physical and ecological processes. It is critical to link physical process and landscape evolution models to quantify hydro-eco-geomorphic feedbacks in marsh environments. A framework that explicitly defines how to integrate these disparate models is a necessary step towards developing a comprehensive marsh model. This technical note (TN) proposes an approach to integrate existing hydrodynamic and geomorphic models with a mechanistic vegetation model into a coupled framework to better simulate salt marsh evolution.

  • Amphibious Uncrewed Ground Vehicle for Coastal Surfzone Survey

    Abstract: The capability of a commercial off-the-shelf amphibious bottom crawling robot is explored for surveying seamless topography and bathymetry across the beachface, surfzone, and very nearshore. A real-time-kinematic (RTK) antenna on a mast was added to the robotic platform, a Bayonet-350 (previously the C2i SeaOx). Data collected from the robot were compared with those collected by the Coastal Research Amphibious Buggy (CRAB) and the Lighter Amphibious Resupply Cargo (LARC), unique amphibious vessels capable of collecting seamless topography and bathymetry in use for decades at the US Army Engineer Research and Development Center’s Field Research Facility (FRF). Data were compared on five different days in a range of wave conditions (Hs < 1 m in 8-m depth) resulting in a root-mean square difference of 8.7 cm and bias of 2 cm for 24 different cross-shore profile comparisons. Additionally, a repeatability test was performed to assess measurement uncertainty. The repeatability test indicated a total vertical uncertainty (TVU) of 5.8 cm, with the highest spatial error at the shoreline.

  • Jacksonville District to lead Key Biscayne CSRM Feasibility Study public presentations

    U.S. Army Corps of Engineers, Jacksonville District, will conduct two public meetings to present and discuss its Key Biscayne Coastal Storm Risk Management (CSRM) Feasibility Study for residents and interested parties.

  • Brookville Lake turns 50, announces celebratory event in 2025

    Brookville Lake, located in Franklin and Union counties in Brookville, Indiana celebrates its 50th Anniversary this month. The dam was built by the U.S. Army Corps of Engineers Louisville District for the primary purpose of flood risk management and became operational in January 1974.

  • ERDC program aims to geospatially map complex, rapidly changing cold regions terrain

    The U.S. Army Engineer and Research Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) recently hosted a defense resiliency program meeting in Hanover, New Hampshire, as part of a project designed to help the Army operate in the complex terrain often found in cold regions.
