USACE to place more than 26 million cubic yards of sand to restore Sandy-damaged projects
BROOKLYN, N.Y. -- The U.S. Army Corps of Engineers is in the process of placing more than 26 million cubic yards of sand along the coastline throughout the northeastern United States to repair and restore coastal storm risk reduction projects previously built by the Corps that were severely impacted by Hurricane Sandy.

The Jan. 7 Los Angeles County wildfires debris removal operation was one of our largest, most challenging missions. More than 1,400 USACE personnel deployed from across the nation and from our district to support debris removal operations. /6

But we did not do this alone. The success of this important mission was the result of strong partnerships with FEMA, Cal OES, LA County, local governments and impacted communities. /5

To date, USACE has removed more than 2.6 million tons of debris — the equivalent of more than 218,000 truckloads. /4

We are proud of our efforts, alongside our partners, to rapidly come to the aid of our fellow citizens in their time of need. In just six months, more than 9,500 properties were cleared — making this the fastest, large-scale wildfire debris removal in USACE history. /3

After the devastating Los Angeles wildfires in January 2025, the U.S. Army Corps of Engineers was laser-focused on removing immediate hazards to public health and safety, and supporting economic recovery by removing structural ash, debris and foundations. /2

This week marks one year since the January 2025 Southern California wildfires began. On Jan. 17, the U.S. Army Corps of Engineers began its debris removal mission, which was a critical step in the road to recovery. https://t.co/iF1yZ5D6CP

PUBLICATION NOTICE: Erosion Thresholds and Rates for Sand-Mud Mixtures
Abstract: Differences in erosion behavior of non-cohesive and cohesive sediments are widely recognized. In many natural environments, sand and mud are not completely separated and occur as mixtures. Significantly less research has been conducted on the erosion behavior of sand-mud mixtures compared to the separate treatment of sand and mud erosion. Sedflume erosion experiments were conducted on sand-mud mixtures with varying mud content to define the relationships between mud content, critical stress for erosion (τc), and erosion rate. Sand-mud mixtures were prepared with three mud sources: (1) non-swelling clay (kaolinite), (2) swelling clay (kaolinite/bentonite), and (3) a swelling, natural mud from the Mississippi River. Test results showed that critical shear stresses of the mixed sediments departed from that of pure sand with mud fractions on the order of 2% to 10%. Peak τc was observed between 30% to 40% mud content, with swelling muds achieving a ten-fold increase in τc while a five-fold increase in τc was measured for kaolinite. Additionally, this study demonstrated that the introduction of small amounts (≤5%) of mud to sand reduced erosion rates by a factor of 10 to 100. This observed abatement of erosion rate has implications for the use of dredged materials in civil and environmental engineering projects.
