    The U.S. Army Corps of Engineers Transatlantic Division stands as a pivotal force in the U.S. Central Command’s area of responsibility. Since the 1950s, the Division has actively shaped the landscape of engineering, design, and construction across the Middle East. Transforming from its initial focus on basic military construction, the Division now leads sophisticated, large-scale infrastructure projects, demonstrating a deep commitment to building capacity and enhancing security in the region. By setting and consistently upholding extraordinary operational standards, it has established itself as the ‘partner of choice.’

  • District awards contract for Kenai coastal erosion project

    The U.S. Army Corps of Engineers – Alaska District awarded a construction contract for the Kenai River Bluffs Erosion Project. Western Marine Construction of Seattle, Washington, will construct a protective rock berm approximately 5,000 feet in length along the north bank of the Kenai River. It will require the placement of about 42,400 cubic yards of armor rock; 33,200 cubic yards of crushed rock and 13,100 cubic yards of gravel base. Funded by the Bipartisan Infrastructure Law, this construction contract award is valued at about $19.3 million.

  • Ecological Modeling of Microbial Community Composition under Variable Temperatures

    Abstract: Soil microorganisms interact with one another within soil pores and respond to external conditions such as temperature. Data on microbial community composition and potential function are commonly generated in studies of soils. However, these data do not provide direct insight into the drivers of community composition and can be difficult to interpret outside the context of ecological theory. In this study, we explore the effect of abiotic environmental variation on microbial species diversity. Using a modified version of the Lotka-Volterra Competition Model with temperature-dependent growth rates, we show that environmentally relevant temperature variability may expand the set of temperature-tolerance phenotype pairs that can coexist as two-species communities compared to constant temperatures. These results highlight a potential role of temperature variation in influencing microbial diversity. This in turn suggests a need to incorporate temperature into predictive models of microbial communities in soil and other environments. We recommend future work to parameterize the model applied in this study with empirical data from environments of interest, and to validate the model predictions using field observations and experimental manipulations.

  • UPDATE: Arkabutla Dam Emergency: Lake levels drop below 210 feet

    Vicksburg, Miss – Lake levels at Arkabutla Dam have dropped below 210’ which greatly decreases the potential of a breach situation. Lake levels at Arkabutla Dam, located in DeSoto and Tate Counties in Northwest Mississippi, can fluctuate quickly especially during the rainy season. Last week, the U.S. Army Corps of Engineers Vicksburg District increased the potential breach emergency status at Arkabutla Dam from ALERT to WATCH because reservoir levels rose to over 210’ due to precipitation and snow/ice melt in the Arkabutla Lake drainage basin. Because lake levels fluctuate quickly, the WATCH designation will continue through the rainy season.

  • USACE Freshwater Harmful Algal Bloom Research and Development Initiative

    Abstract: Harmful Algal Blooms (HABs) represent a significant and costly threat to our nation’s economy and natural resources. This report outlines the US Army Corps of Engineers, Engineer Research and Development Center’s (USACE-ERDC’s) approach to deliver scalable technologies for prevention, early detection, and management of HABs to reduce HAB event frequency, severity, and duration.
