  • 23-0228; Olivier Plantation, LLC

    Olivier Plantation, LLC. is requesting authorization, to construct a 10-slip boat shed, deck and parking area on the flood side of the Lake Pontchartrain and Vicinity-Hurricane and Storm Damage Risk Reduction System (LP&VHSDRRS) floodwall and along the bank of the Mississippi River-Gulf Outlet Canal (MRGO). The 10-slip boat shed will have an elevated deck approximately 200' leading to the slips. The parking area and driveway will be constructed using TrueGrid Root Grass pavers to keep the appearance the same.

  • Characterising Earth Scent

    Abstract: Rationale. Earth scent is the odour emitted from soils. This scent, primarily comprising the alcohols geosmin and 2-methylisoborneol (MIB), has not been fully characterised, but offers high potential for use as an environmental interrogation tool. Methodology. We utilised our field- based, solid-phase microextraction fibre method to test the hypothesis that soil activity and soil property variation can be detected in situ by comparing biogenic volatile emissions. Results. We eliminated sources of error utilising field-based sampling with these fibres, concluding that room temperature storage for up to 7 days is acceptable with minimal loss. Variation in individual fibre affinity for both compounds was higher than expected but no measured concentrations were observed to constitute outliers. Disturbance of minor soil volumes led to significantly higher emission of both compounds over background levels. Soil texture and soil cover had a significant effect on the emission of both compounds. Simulated rainfall, producing the characteristic odour known as petrichor, initiates elevated emission of geosmin. Background (undisturbed soil) concentrations of MIB were occasionally detectable during some sampling events, but geosmin concentrations in the air were always below detection limits without soil disturbance. Virtually all background and disturbed soil samples contained much higher concentrations of MIB compared to geosmin, but geosmin variation between replicates and experimental units was much lower. Discussion. Soil disturbance and soil property variation can be remotely detected using emission of volatile compounds. Correlating emission from the soil with respect to disturbance events and environmental properties could yield a powerful new tool for acquiring soil information.

  • Vicksburg District Partners with We Work the Waterways

    VICKSBURG, Miss. – The U.S. Army Corps of Engineers (USACE) Vicksburg District partnered with Inland River Ports and Terminals to host a We Work the Waterways event on Feb. 15 at The Jesse Brent Lower Mississippi River Museum. The event is an immersive interaction day to educate high school students in the area on the importance of waterborne transportation and the diversity of career pathways available on the waterways. We Work the Waterways brings the industry to the students; through education, hands-on learning, and engaging with maritime representatives.

  • Galveston District celebrates 144 years

    On February 25, 1880, The U.S. Army Corps of Engineers (USACE) established its first engineer district in Texas on an island off the Gulf Coast. One hundred forty-four years, 52 district commanders, and several major hurricanes later, the Galveston District (SWG) continues to play a key role in keeping the country’s vital waterways open and protecting coastal Texas communities.

  • Wilford Hall: Preserving a Legacy, Brick by Brick

    Wilford Hall Medical Center, located on Joint Base San Antonio-Lackland Air Force Base, Texas, was once the flagship of military medicine, named after the medical pioneer, Brig. Gen. Wilford F. Hall. With early beginnings in 1942, as a 100-bed hospital, the medical center quickly grew to a 1,200-bed, Level 1 trauma center by 1957. The Level 1 designation expanded resources and capabilities for handling patients with complex and life-threatening injuries, a service that extended beyond the Air Force community, and into the surrounding civilian community as well.
