  • From delamination to durability: How Fiber-Reinforced Polymer is fortifying Albeni Falls Dam's Gate 3

    Discovered in April 2024 during routine maintenance, Gate 3, one of Albeni Falls Dam’s 10 spillway gates revealed defective steel, likely a consequence of the original 1950s fabrication process. While a long-term plan for complete gate replacement is underway, the immediate need was for a robust, interim solution to bring Gate 3 back into service and restore the dam's full operational flexibility. Fiber-Reinforced Polymer (FRP) offers a technically superior Band-Aid, providing significant structural enhancement, a glimpse into the future of dam maintenance and a testament to modern engineering ingenuity.
  • Corps of Engineers makes adjustments to Lac qui Parle Dam

  • MKARNS Nav Notice No. SWL 25-46 SAILING INSTRUCTION NM 221.2 to NM 221.7

    Due to shoaling, mariners are advised that until further notice, both upbound and downbound tows should run the green line from NM 221.2 to 221.7.
  • MKARNS Nav Notice No. SWL 25-45 Lock 9 Closure - High flows

    Due to high flows on the McClellan-Kerr Arkansas River Navigation System, the Arthur V. Ormond Lock (No. 9) NM 176.9 is closed to traffic. The lock will reopen as the flows drop to safe navigation levels.
  • Remaining Phase 3 options awarded for New Lock at the Soo

    U.S. Army Corps of Engineers, Detroit District’s New Lock at the Soo project in Sault Ste. Marie, Michigan, awards a total of $95.3 million for remaining Phase 3 options to Kokosing Alberici Traylor, LLC (KAT) of Westerville, Ohio. The remaining Phase 3 options include Option 4: Downstream Work ($44.9 million), Option 5: Hands Free Mooring ($24.2 million), and Option 6: Downstream Ship Arrestors ($26.2 million).

  • Entropy-Based Guidance of Deep Neural Networks for Accelerated Convergence and Improved Performance

    Abstract: Neural networks have dramatically increased our capacity to learn from large, high-dimensional datasets across innumerable disciplines. However, their decisions are not easily interpretable, their computational costs are high, and building and training them are not straightforward processes. To add structure to these efforts, we derive new mathematical results to efficiently measure the changes in entropy as fully-connected and convolutional neural networks process data. By measuring the change in entropy as networks process data effectively, patterns critical to a well-performing network can be visualized and identified. Entropy-based loss terms are developed to improve dense and convolutional model accuracy and efficiency by promoting the ideal entropy patterns. Experiments in image compression, image classification, and image segmentation on benchmark datasets demonstrate these losses guide neural networks to learn rich latent data representations in fewer dimensions, converge in fewer training epochs, and achieve higher accuracy.
  • No Explosives, No Problem, Sapper Training Provides Tactical Skills and Strategic Mindset

    Lieutenant Colonel Donald Lew, Deputy Commander of the U.S. Army Corps of Engineers Middle East District, exemplifies how the Sapper spirit endures beyond the battlefield. A combat engineer with a distinguished military career, Lew now helps deliver critical infrastructure in support of U.S. and partner nation defense efforts across the Middle East. As USACE celebrates 250 years of engineering excellence, Lew’s journey underscores the strategic value of combining military leadership with the deep expertise of a civilian workforce, building not just structures but lasting global partnerships.
