  • ERDC’s Pittman honored with FLC’s Laboratory Director of the Year award

    Dr. David Pittman, director of the U.S. Army Engineer Research and Development Center (ERDC), has been chosen for the 2021 Director of the Year award by the Federal Laboratory Consortium (FLC).

  • CRREL inducts Pangburn into Gallery of Distinguished Employees

    The Engineer Research and Development Center (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) honored its researchers, scientists and engineers during an awards ceremony in Hanover, New Hampshire, in December 2020. The final award, the Distinguished Employee Award, recognized the lifelong contributions made by Tim Pangburn, who started working for CRREL in 1978 as a civil engineering technician. He retired in 2017 as a director for the U.S. Army Corps of Engineers Remote Sensing (RS)/Geographic Information Systems (GIS) Center of Expertise.

  • Synergy for safety: ERDC partners with local fire department for increased protection

    When it comes to emergency response, it’s said that an ounce of prevention is worth a pound of cure. For the U.S. Army Engineer Research and Development Center (ERDC) and the City of Vicksburg Fire Department (VFD), the old adage is more than just a saying, it’s a blueprint for success. Until the mid-1990s, ERDC was home to its own fire department on the Waterways Experiment Station. After that, fire protection was transferred over to the City of Vicksburg.

  • Optical and Acoustical Measurement of Ballistic Noise Signatures

    Abstract: Supersonic projectiles in air generate acoustical signatures that are fundamentally related to the projectile’s shape, size, and velocity. These characteristics influence various mechanisms involved in the generation, propagation, decay, and coalescence of acoustic waves. To understand the relationships between projectile shape, size, velocity, and the physical mechanisms involved, an experimental effort captured the acoustic field produced by a range of supersonic projectiles using both conventional pressure sensors and a schlieren imaging system. The results of this ongoing project will elucidate those fundamental mechanisms, enabling more sophisticated tools for detection, classification, localization, and tracking. This paper details the experimental setup, data collection, and preliminary analysis of a series of ballistic projectiles, both idealized and currently in use by the U.S. Military.

  • Hydrologic Impacts on Human Health: El Niño Southern Oscillation and Cholera

    Abstract: A non-stationary climate imposes considerable challenges regarding potential public health concerns. The El Niño Southern Oscillation (ENSO) cycle, which occurs every 2 to 7 years, correlates positively with occurrences of the waterborne disease cholera. The warm sea surface temperatures and extreme weather associated with ENSO create optimal conditions for breeding the Vibrio cholerae pathogen and for human exposure to the pathogenic waters. This work explored the impacts of ENSO on cholera occurrence rates over the past 50 years by examining annual rates of suspected cholera cases per country in relation to ENSO Index values. This study provides a relationship indicating when hydrologic conditions are optimal for cholera growth, and presents a statistical approach to answer three questions: Are cholera outbreaks more likely to occur in an El Niño year? What other factors impact cholera outbreaks? How will the future climate impact cholera incidence rates as it relates to conditions found in ENSO? Cholera outbreaks from the 1960s to the present are examined focusing on regions of Central and South America, and southern Asia. By examining the predictive relationship between climate variability and cholera, we can draw conclusions about future vulnerability to cholera and other waterborne pathogenic diseases.

  • Contingency Basing Integration Training, Evaluation Center tests U.S. Army Prime Power School students

    The Contingency Basing Integration Training and Evaluation Center (CBITEC), in Fort Leonard Wood, Missouri, provides U.S. Army Prime Power School students with testing facilities throughout their year-long training program. While the students encounter a variety of course challenges, the hands-on training provided and facilitated by the CBITEC is considered the most demanding. CBITEC is a U.S. Army Engineer Research and Development Center (ERDC), Construction Engineering Research Laboratory (CERL) facility that supports the operational energy continuum and safely trains the warfighter to tackle the nation’s power challenges.

  • ERDC partners with University of Southern Mississippi to maximize Gulf oyster habitat restoration

    The U.S. Army Engineer Research and Development Center (ERDC) has announced a three-year research collaboration with the University of Southern Mississippi (USM) to create oyster reef habitat in the northern Gulf of Mexico.

  • Incorporating Color Change Propensity into Dredged Material Management to Increase Beneficial Use Opportunities

    Dredged materials provide a number of beneficial use opportunities, including beach nourishment, habitat creation and restoration, and other activities. In situ sediment color is important for determining aesthetic and habitat suitability, for beach nourishment, and for other projects. However, dredged materials must meet locally established color compatibility requirements (for example, material cannot be too dark). Often, potential sediment sources are close to meeting specified color thresholds, and previous observations suggest that sediments lighten over time. In response to these observations, this study quantified sediment color change potential in a dredged m material management context. Results indicate that dredged material sediment color responded to changes in secondary color components, sediment mixing, and photolytic bleaching improving the sediment color for beneficial use application. Findings allowed for development of a conceptual color change capacity framework and supported development of tools for resource managers to incorporate color change dynamic into planning and operations activities. The following report provides a framework for determining the color change capacity of dredged materials using (1) a comprehensive laboratory approach and (2) a semiquantitative index based on source material and placement location conditions. These tools allow practitioners to incorporate dredged-material color change into resource management decisions, thus increasing beneficial use opportunities.

  • Broadening the scope of post-wildfire flood risk management

    As firefighters worked diligently to extinguish a notable number of wildfires this season, researchers with U.S. Army Engineer Research and Development Center’s (ERDC) post-wildfire flood risk management team took a step back to evaluate how they could improve their efforts in assisting with the devastating effects of the fires.

  • U.S. Army Engineer Research and Development Center assists Kansas City Corps with hydrodynamic dredge

    In a demonstration of collaboration and innovation, the U.S. Army Engineer Research and Development Center deployed an experimental asset and team of experts to the Missouri River in the Kansas City District, U.S. Army Corps of Engineers, to assist in dredging shallow areas called shoals in the navigation river channel.
