  • ERDC robotics team advances future of combat engineering at PC-C5

    A team from the U.S. Army Engineer Research and Development Center (ERDC) recently played a key role in a major Army exercise called Project Convergence Capstone 5 (PC-C5). During this event, ERDC’s Robotics for Engineer Operations (REO) put their robotic technologies to the test in realistic, hands-on scenarios that simulate combat situations, showing how systems perform and hold up under pressure, making an important contribution to Army readiness.

  • Chickamauga Lock approach wall receives second nose pier delivery

    Progress continues on the Chickamauga Lock Replacement Project as the U.S. Army Corps of Engineers Nashville District successfully delivered a second massive nose pier, a key structure that guides vessels into the new lock chamber. The milestone keeps the project on track for contract completion in 2026 and full operation by 2028, with the new lock expected to boost capacity by 80% and improve commercial navigation efficiency on the Tennessee River.

  • Millions in federal aid help shoreline facilities adjust to changing river levels

    Dozens of shoreline facilities along the Monongahela River have been receiving millions of dollars in federal aid to adjust to river level changes.

  • Potential Benefits of Subaqueous Soil Data on Department of Defense Installations

    Purpose: Many domestic and international US Department of Defense (DoD) installations are located in coastal areas. Recent advances in the classification and mapping of subaqueous soils, which occur in shallow freshwater and marine environments, has the potential to benefit US military operations in several different ways. This technical note communicates the importance of subaqueous soil classification and describes how subaqueous soil information can inform the management of natural resources, infrastructure and transportation, mitigation of coastal storm risk, protection of the coast from natural threats, and the understanding of nearshore environments in the US and abroad.

  • Evaluation of NiTech FG-NDGB Pelletized Asphalt for Rapid Airfield Damage Recovery Applications

    Purpose: The NiTech Corporation’s FG-NDGB Pelletized Asphalt (PA), herein referred to as NiTech PA, was identified as a surfacing material for Rapid Airfield Damage Recovery (RADR) applications by the US Air Force Civil Engineer Center (AFCEC). AFCEC tasked the US Army Engineer Research and Development Center (ERDC) with evaluating NiTech PA by conducting full-scale crater repairs and applying simulated F-15E aircraft loads. The properties of the repair material were also to be obtained via laboratory characterization testing.

  • U.S. Army Corps of Engineers reduces releases to Caloosahatchee Estuary under Recovery Operations

    U.S. Army Corps of Engineers (USACE) Jacksonville District will further reduce releases through the S-79 into the Caloosahatchee River Estuary as part of Lake Okeechobee Recovery Operations on April 19. Current projections show conditions are favorable for successfully reaching recovery metrics if dry conditions continue.

  • U.S. Army Corps of Engineers to begin dredging at Holland Harbor
