  • ROTC Cadet Temin Sohn’s Summer Experience at the U.S. Army Corps of Engineers Field Office in Jordan

    The U.S. Army Corps of Engineers (USACE) Transatlantic Middle East District (TAM) hosted ROTC Cadet Temin Sohn as part of its cadet summer training program, providing him with a unique experience in Jordan. Sohn, a chemistry student at the University of Southern California, participated in construction site visits and cultural exchanges, shadowing TAM professionals and gaining firsthand knowledge of USACE’s operations. He appreciated the guidance from Army officers, including their positive mindsets and diverse experiences. His time in Jordan, which included visiting the historic site of Petra, left a lasting impression, and he highly recommends the program for its invaluable insights into military and engineering careers in the Middle East.

  • The Forefront: A Review of ERDC Publications, Summer 2024

    Abstract: As the main research and development organization for the US Army Corps of Engineers (USACE), the Engineer Research and Development Center (ERDC) helps solve our nation’s most challenging problems. With seven laboratories under the ERDC umbrella, ERDC expertise spans a wide range of disciplines. This issue of the Forefront highlights several ERDC reports from FY22, many of which were highly recognized and widely downloaded. The Forefront team was honored in FY23 to receive both the Information Technology Laboratory’s Communication Award and the ERDC Communication Award for our Summer 2022 issue of the Forefront. The Forefront team and the Information Science and Knowledge Management Branch (ISKM) as a whole are committed to staying current with best practices and exploring new techniques to communicate ERDC’s research excellence. Through quality publications, dynamic presentations, and ongoing training opportunities, ISKM strives not only to support ERDC but also to blaze a path to clear, concise, and engaging scientific communication products. Remember, if it ever takes you more than five minutes to find an answer, contact us. We are here to help!

  • The Arctic Deployable Resilient Installation Water Purification and Treatment System (DRIPS): Microgrid Integration with Geoenabled Water Production and Disinfection Systems for Installations

    Abstract: The purpose of the Arctic Deployable Resilient Installation water Purification and treatment System (DRIPS) is to be a critical asset in disaster response and military operations by providing a reliable and effective means of producing potable water and disinfection in a challenging and unpredictable environment, such as in an extremely cold climate. The objective of this effort was to deliver, integrate, and demonstrate the Arctic DRIPS to show that it can provide drinkable water to users of the microgrid within polar climate zones. Its adaptability, mobility, and comprehensive water treatment capabilities make it an invaluable resource for addressing water-related emergencies and water disruptions and for sustaining critical missions. It also addresses a point of need by improving the ability to meet demands while reducing convoy requirements and the logistical foot-print and ensuring the well-being of affected installations during disaster responses, training operations, normal water disruptions, and emergency preparation. The DRIPS was delivered to Fort Wainwright, a sub-Arctic installation, to demonstrate the integration of a water treatment component within a microgrid structure and to help them be better prepared to meet their water and energy requirement goals. The microgrid integration requirements were met upon implementation of this project.

  • Case Study of Continental-Scale Hydrologic Modeling’s Ability to Predict Daily Streamflow Percentiles for Regulatory Application

    Abstract: Regulatory practitioners use hydroclimatic data to provide context to observations typically collected through field site visits and aerial imagery analysis. In the absence of site-specific data, regulatory practitioners must use proxy hydroclimatic data and models to assess a stream's hydroclimatology. One intent of current-generation continental-scale hydrologic models is to provide such hydrologic context to ungaged watersheds. In this study, the ability of two state-of-the-art, operational, continental-scale hydrologic modeling frameworks, the National Water Model and the Group on Earth Observation Global Water Sustainability (GEOGloWS) European Centre for Medium-Range Weather Forecasts (ECMWF) Streamflow Model, to produce daily streamflow percentiles and categorical estimates of the streamflow normalcy was examined. The modeled stream-flow percentiles were compared to observed daily streamflow percentiles at four United States Geological Survey stream gages. The model's performance was then compared to a baseline assessment methodology, the Antecedent Precipitation Tool. Results indicated that, when compared to baseline assessment techniques, the accuracy of the National Water Model (NWM) or GEOGloWS ECMWF Streamflow Model was greater than the accuracy of the baseline assessment methodology at four stream gage locations. The NWM performed best at three of the four gages. This work highlighted a novel application of current-generation continental-scale hydrologic models.
