  • CRREL workshop advances Army’s snow science research

    The U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) hosted a snow sciences workshop to advance the understanding of the topics, unique aspects, and elements in common among Army-funded snow research contracts. Special emphasis was placed on why the Army cares about snow, what impacts it has on Warfighter functions and operational planning, and how the Army may operate in the future.

  • The Geophysical Survey of Mare Island Naval Cemetery, California

    Abstract: The US Congress codified the National Historic Preservation Act of 1966 (NHPA), the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requires federal agencies to address their cultural resources, which are defined as any prehistoric or historic district, site, building, structure, or object. Section 110 of the NHPA requires federal agencies to inventory and evaluate their cultural resources, and Section 106 requires them to determine the effect of federal undertakings on those potentially eligible for the NRHP. This project was undertaken to provide the US Department of Veterans Affairs (VA), National Cemetery Administration (NCA), with a geophysical survey of Mare Island Naval Cemetery. The approximately 2.5-acre cemetery is located in Vallejo, California, and contains more than 900 burials. Mare Island Naval Cemetery is part of the Mare Island Naval Shipyard Historic District, which was listed concurrently on the National Register of Historic Places and as a national historic landmark in 1975.

  • Lower James River Sediment Transport Modeling: Jordan Point

    Abstract: US Army Corps of Engineers–Norfolk District (NAO) requested assistance from the US Army Engineer Research and Development Center (ERDC) to examine currently used placement sites within the James River, Virginia, initiative area, determine potential risk to critical environmental receptors during placement, and predict the life cycle of the placement sites. The focus of the analysis within this work is the Jordan Point placement site. The far-field, fate-transport modeling at Jordan Point shows relatively low maximum values of suspended sediment concentration (less than 40 mg/L) and deposition values (less than 0.2 cm). Material that is placed at Jordan Point appears to quickly disperse through the system, depositing in thin layers at specific areas. The life-cycle analysis performed for the Jordon Point placement site yielded an estimated useable project life of the Jordan Point placement sites of 26 years with an uncertainty of ±4 years. Analysis showed that 97% of the net sediment deposition in the navigation channel in proximity to this site is from the upper James River, 2% is from downstream sources, and 1% is from the two Jordan Point placement sites.

  • Exploring the Convergence of Resilience Processes and Sustainable Outcomes in Post-COVID, Post-Glasgow Economies

    Abstract: Resilience and sustainability have each offered a path forward for post-COVID economic recovery and a post-Glasgow global financial order. Yet, the relationships between these two concepts are largely unexplored in economic policy and investment strategies. In light of emerging systemic risks and global demands for more resolute investments in resilience and sustainability, this perspective article took the position that policymakers must begin to draw greater conceptual, empirical, and practical linkages between sustainability and resilience. This perspective article provided a simplified framework for understanding the positively reinforcing, negatively conflicting, and neutral relationships between different types of resilience and sustainability consistent with two propositions. The Reinforcement Proposition argues (i) that various resilience processes may drive sustainable outcomes, and/or (ii) that an allocation of sustainable resources may reinforce resilience processes, as well as the transformative adaptation of markets. Conversely, the Conflict Proposition argues (i) that certain resilience processes may perpetuate stability features that may thwart an economic transition toward sustainability, and/or (ii) that certain sustainability outcomes associated with reorganized economic structures and relationships may undermine resources for resilience. This framework provides policymakers with an opportunity to evaluate the convergent and conflicting trade-offs of resilience processes and sustainable outcomes.

  • Corps continues controlled water releases following heavy rainfall, emphasizes public safety near dams

    The U.S. Army Corps of Engineers Nashville District continues to actively manage water releases following significant rainfall across the Cumberland River Basin this past weekend. While precipitation has moved out of the region, ongoing reservoir operations are critical to maintaining dam safety and regulating river stages throughout the region.

  • USACE Louisville District to begin releasing water from Buckhorn and Carr Creek lakes today

    The U.S. Army Corps of Engineers Louisville District continues to monitor the dams at Buckhorn Lake, Buckhorn, Kentucky, and Carr Creek Lake, Sassafras, Kentucky, following severe flooding in eastern Kentucky. The Buckhorn and Carr Creek Dams on the Middle Fork and the North Fork, respectively, of the Kentucky River are currently storing water and operating as intended.

  • Corps begins Phase I floodfight activities along the White River near Des Arc, Arkansas

    The Memphis District, U.S. Army Corps of Engineers (USACE) has begun Phase I floodfight activities along the White River in Arkansas due to high river stages. The area of current flooding is along the White River near Des Arc, Arkansas.

  • Corps of Engineers seeks public input on Lock and Dam 7 outdraft project

    The U.S. Army Corps of Engineers, St. Paul District, will host an open house on its Lock and Dam 7 outdraft weir modification project Feb. 27, from 5:30 p.m. – 7 p.m. in the Nursing Center at Viterbo University, 10th Street, La Crosse, Wisconsin. There is no formal presentation scheduled.

  • Jacksonville District to begin maintenance dredging of IWW and Ponce de Leon Inlet in Volusia County

    U.S. Army Corps of Engineers, Jacksonville District (USACE), will begin maintenance dredging of the federal navigation channels of the Intracoastal Waterway (IWW) and Ponce de Leon Inlet in Volusia County, sometime in early April. Mobilization of construction equipment will start the week of March 10, 2025.

  • Frosty reservoir conditions increase importance of winter safety and first-responder partnerships

    Frozen lakes and snow-covered landscapes offer incredible sights for visitors at federal reservoirs, but a wintry stroll around icy waters can quickly turn dangerous in unexpected ways.
