  • Norfolk Harbor deepening project advances with critical contract award

    On the heels of the Bipartisan Infrastructure Law earlier this year, the Norfolk Harbor and Channels Improvement Project’s federal sponsor, Norfolk District, U.S. Army Corps of Engineers, announced more good news.

  • Qualification of Hanna Instruments HI9829 for the Environmental Toolkit for Expeditionary Operations

    Abstract: A new, commercially available, field-portable water sensor was evaluated for efficacy during operation and compatibility with current Environmental Toolkit for Expeditionary Operations (ETEO) software. The ETEO provides sensors to Soldiers to rapidly identify and quantify environmental contamination in soil, air, and water at potential new base sites during initial reconnaissance to ensure safety and minimize unnecessary remediation efforts by the Army. In addition to streamlined environmental baseline survey (EBS) reporting, the ETEO can provide rapid analysis of potential environmental contamination to support various Military applications. The Hanna Instruments HI9829 multiparameter water meter was selected following a survey of commercial off-the-shelf (COTS) technologies and analyzed by researchers from the US Army Engineer Research and Development Center (ERDC) for inclusion in the ETEO design since it can rapidly and accurately measure 14 different properties. Usability tests were conducted with researchers unfamiliar with the technology, and a set of standard operating procedures (SOPs) were developed to operate the device. The software for the tool was successfully integrated into the ETEO system for rapid data analysis. The HI9829 has been demonstrated in various scenarios at ERDC and other locations; including Ft. Leonard Wood, MO, at which several visitors reviewed the operation of the equipment and other ETEO technologies. The Thermo Scientific Gemini, another sensor, which can detect organic constituents in various matrices via Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy was also investigated but eliminated from the ETEO design as it could not adequately detect a Military-relevant compound in an environmental matrix. Regardless, the addition of the HI9829 provides water quality monitoring to the ETEO design and greatly improves its capability to address various applications.

  • U.S. Army Corps of Engineers and the Federal Emergency Management Agency installs first generator at Diagnostic Treatment Center of Guanica, Puerto Rico

    The U.S. Army Corps of Engineers (USACE) successfully installed a 240 Kva generator provided by the Federal Emergency Management Agency (FEMA) at the Diagnostic Treatment Center of Guanica, Puerto Rico Sept. 21, providing sufficient temporary power to the facility until commercial power is restored.

  • Potential Hydrogen Sulfide (H2S) concerns at Clendening Lake

    HUNTINGTON, W.Va. - The Huntington District of the U.S. Army Corps of Engineers has determined that conditions exist in the outlet works area at Clendening Lake in southwestern Harrison County in Washington and Nottingham townships, Ohio that could result in the presence and possible release of hydrogen sulfide (H2S) gases.

  • USACE to close Hiram M. Chittenden large and small locks for inspections, Oct. 31

    The Hiram M. Chittenden large and small locks will close to all marine traffic Oct. 31, from 7 a.m. to 3 p.m., to inspect the large locks, open a saltwater drain screen structure, and to conduct large lock sill and pump discharge inspections, in preparation for the large lock dewatering outage.

  • Ship Simulator of the Future in Virtual Reality

    Introduction: The Army’s modernization priorities include the development of augmented reality and virtual reality (AR/VR) simulations for enabling the regiment and increasing soldier readiness. The use of AR/VR technology at the U.S. Army Engineer Research and Development Center (ERDC) is also growing in the realm of military and civil works program missions. The ERDC Coastal and Hydraulics Laboratory (CHL) has developed a ship simulator to evaluate bay channels across the world; however, the current simulator has little to no physical realism in nearshore coastal regions (Figure 1). Thus, the ERDC team is researching opportunities to advance ship simulation to deliver the Ship Simulator of the Future (SSoF). The SSoF will be equipped with a VR mode and will more accurately resolve nearshore wave phenomena by ingesting precalculated output from a Boussinesq-type wave model. This initial prototype of the SSoF application is intended for research and development purposes; however, the technologies employed will be applicable to other disciplines and project scopes, including the Synthetic Training Environment (STE) and ship and coastal structure design in future versions.

  • USACE Archaeological Program

    When you think “archaeology” do you think “U.S. Army Corps of Engineers?” Probably not. Archaeology brings up images of Indiana Jones, dusty tombs and getting chased out of caverns by giant rolling boulders. Yet, despite this, USACE curates the second largest collection of cultural resources in the United States, second only to the Smithsonian Institution.
