  • It’s electric! One-of-a-kind fish barrier project aims to preserve walleye population

    From a young age, most are taught electricity and water don’t mix. While there is certainly truth to this statement, there are some exceptions. At Rathbun Lake in southern Iowa, engineers and scientists are working to design a one-of-a-kind electric barrier to deter fish from escaping downstream of the reservoir—all happening under water. The Kansas City District, U.S. Army Corps of Engineers operates and maintains the dam and reservoir at Rathbun Lake, but the Iowa Department of Natural Resources maintains the fish hatchery and fish population found there. Together, along with partners from Iowa State University and the private sector, USACE and the Iowa DNR are hard at work to make the seemingly impossible happen—create a safe, effective underwater electric fish barrier to keep walleye in the reservoir.

  • Infrastructure Innovation: New Poe Lock arrestor arm is the largest U.S. civil works component produced by 3D printer

    As America’s civil works infrastructure ages, managers need innovative solutions to replace parts that have been in service for nearly a century. Often, these original components were fabricated using vintage material and manufacturing methods, making them costly, burdensome and time-consuming to replace. Responding to this need, the U.S. Army Corps of Engineers (USACE) is employing cutting-edge 3D-printing techniques to manufacture these parts faster and at a lower cost while maintaining, and even improving, their properties.

    As America’s civil works infrastructure ages, managers need innovative solutions to replace parts that have been in service for nearly a century. Often, these original components were fabricated using vintage material and manufacturing methods, making them costly, burdensome and time-consuming to replace. Responding to this need, the U.S. Army Corps of Engineers (USACE) is employing cutting-edge 3D printing techniques to manufacture these parts faster and at a lower cost while maintaining, and even improving, their properties. In early March, the USACE Detroit District installed the largest U.S. civil works infrastructure component produced by a 3D printer – a 12-foot-long metal part for the ship arrestor system on the Poe Lock, one of the two active locks on the Soo Locks facility. Building on years of research performed by the U.S. Army Engineer Research and Development Center (ERDC), the part was manufactured in 12 weeks, compared to a projected 18-month lead time for conventional manufacturing. The part was installed, tested and commissioned during the Soo Locks’ winter maintenance cycle. The rapid repair ensured normal operations at Poe Lock, a major transit point for domestic iron ore.

  • Engineering Science in Okinawa

    It’s not uncommon to find members of the U.S. Army Corps of Engineers (USACE) interacting with students in a school setting. This is part of the USACE science, technology, engineering, and math (STEM) initiative, worldwide. Overseas in Japan, one would think you could find America’s Engineers working together with children at any number of Department of Defense Education Activity (DoDEA) schools as well, and they are. Engineers from the USACE’s Japan Engineer District work directly with DoDEA students and classes, promoting STEM and engineering in general.

  • Army engineers teach 125 students about STEM in Alaska

    The U.S. Army Corps of Engineers – Alaska District hosted 125 students from the Fairbanks community for STEM activities on Aug. 5 at the Chena River Lakes Flood Control Project near North Pole, Alaska.

  • THE POWER OF ERDC: ERDC 2020–2030 STRATEGY

    Abstract: The ERDC 2020–2030 Strategy outlines the origination of the organization, future direction, and the methods used to accomplish its research and development mission. The Strategy details the Ends (where we are going and why), the Ways (how we will get there), and the Means (the resources needed to get there) by which we will achieve the US Army Engineer Research and Development Center (ERDC) strategy. To realize its vision and maintain its world-class status, ERDC strives to be the go-to organization for the Warfighter and the nation to solve large complex problems in its mission space. To strengthen the outcomes from the Ends, Ways, and Means, ERDC has adopted the philosophy of the Understand- Predict-Shape (UPS) paradigm. The UPS paradigm maximizes the potential of ERDC’s current research programs and helps contemplate, develop, and define the organization’s future portfolio. UPS represents a holistic view of the operational environment: How to better Understand the Present, Predict the Future, and Shape the Outcome. The ERDC leadership team has looked toward the future and defined major strategic Science and Technology campaigns that offer challenges that ERDC can, and should, effectively address.
