  • U.S. Army Corps of Engineers awards $40 million contract for Chesapeake Bay restoration project

    The U.S. Army Corps of Engineers, Baltimore District, awarded a $39.9 million contract to Seacoast

  • Great Lakes Costal Wetland Revitalized on Ohio’s Lake Erie Shoreline

    The U.S. Army Corps of Engineers, Buffalo District and City of Port Clinton celebrated the completion of construction on a five-year coastal restoration project with a final planting of native species on the beach. The $1.9 million Great Lakes Fishery and Ecosystem Restoration Program Port Clinton Coastal Restoration Project has expanded costal wetland – a rarity along Ohio’s Lake Erie Shoreline – by 1.4 acres, removed invasive plant species, and created a more diverse habitat for wildlife to thrive in and people to enjoy.

  • Shady Creek Recreation Area Trick-or-Treat in the Park – Oct. 26

    The U.S. Army Corps of Engineers Mississippi River Project is hosting Trick-or-Treat in the Park at Shady Creek Recreation Area. The event will be held on Saturday, October 26 from 2 - 4 p.m. Shady Creek is located at 3550 Hwy 22 in Muscatine, IA.

  • The Conquest of Hell Gate: A Historic Feat in New York Harbor

    In the late 19th century, the U.S. Army Corps of Engineers undertook one of the most ambitious and challenging engineering feats in American history—the removal of hazardous rocks from Hell Gate, a narrow and treacherous strait in the East River of New York. This critical waterway was a major route for maritime transportation but was notorious for its perilous conditions due to powerful tidal currents and submerged rocks that obstructed navigation.

  • Performance of High-Resolution, Acoustic Mapping Systems in a Fluid-Mud Environment : Testing the Effectiveness and Viability of High-Resolution, Hydrographic Survey Systems in a Fluid-Mud Environment

    Abstract: This study explores the use of high-resolution acoustic mapping systems to penetrate fluid-mud layers by quantitatively relating depth with operating frequency. Prior to this study, multibeam surveys have proven be an effective method to elucidate the seafloor and collect bathymetric data on various bodies of water including rivers, lakes, bays, and the oceans. These techniques are regularly used on US Army Corps of Engineers dredged and federally maintained navigation channels. The objective of the study was to test the effectiveness of commercial off-the-shelf, low-frequency, high-resolution acoustic survey systems to penetrate fluid mud and if so, determine the density at penetration. The testing method combined multibeam echosounder, sub-bottom profiler, and single-beam echo sounder. In addition, in situ testing was conducted to determine the density of fluid-mud layers using a RheoTune profiler and laboratory testing. Results indicate that the use of currently available, bathymetric mapping systems operating at 90 kHz and higher are incapable of penetrating fluid mud in riverine and coastal shallow water conditions. This study demonstrates that while multibeam technology is effective at penetrating the water column, current frequencies available on the market are unable to penetrate fluid-mud layers in a riverine and shallow-water environment.

  • Unified Facilities Criteria and Unified Facilities Guide Specifications for Sustainable Military Construction : Concrete, Asphalt, Wood, and Life-Cycle Assessment Perspectives

    Abstract: Construction materials such as concrete, asphalt, and wood are essential components for Department of Defense (DoD) Military Construction (MILCON) and construction for contingency operations around the world. From housing facilities, to airfields, to magazines and hardened structures, each of these materials fulfill numerous Army building applications. However, greenhouse gas (GHG) emissions stemming from the manufacturing, application, maintenance, and disposal of concrete and steel exact a significant climate burden. Thus, due to their pervasive use and commodity status, the advancement of sustainable concrete, asphalt, and wood materials are a critical driver for GHG mitigation. This report communicates a first step toward decarbonization-focused updates to UFC and UFGS by outlining major specifications related to concrete, asphalt, and wood with near- and long-term strategies to facilitate modernization. The Engineer Research and Development Center (ERDC) is poised to make a significant impact on the identification and integration of sustainable materials to meet regulatory goals for the re-duction of GHG emissions in MILCON. New guidance will be integrated into UFC and UFGS by leveraging unique re-search, development, test, and evaluation (RDT&E) capabilities in materials science, life-cycle assessment, and federal relationships with discipline working groups

  • Hydrologic Engineering Center’s Quest for Sustainable Continuous Improvement

    The U.S. Army Corps of Engineers, Institute for Water Resources, Hydrologic Engineering Center (HEC) has been developing software for decades, and during that time, the technologies to develop, deliver, and support the software have profoundly changed. Although HEC tools are considered industry-standard, HEC recognizes the need to improve the quality of code, development process, user and developer experience, and support for the U.S. Army Corps of Engineers’ mission and the greater hydrologic profession.
