Pocket-area project prepares for smoother work in year two
Greater Sacramento, California, is considered one of the most at-risk regions in the United States for catastrophic flooding. Its location, at the confluence of the Sacramento and American Rivers, has made it necessary to rely on an aging system of levees, weirs, and passes, as well as Folsom Dam upstream, to reduce flooding.

Maj. Gen. Graham visits notable Memphis District Grand Prairie Project
Memphis District Commander Col. Zachary Miller and other district leaders hosted the Senior Official Performing the Duties of the Assistant Secretary of Army (Civil Works), Mr. Vance Stewart, and USACE's Deputy Commanding General for Civil and Emergency Operations, Maj. Gen. William (Butch) H. Graham, on March 11, 2021. During his tour, Graham stopped by the Grand Prairie Project to learn more about conserving groundwater resources throughout the region.

Evaluating the engineering benefits of Florida’s mangrove forests
Along the Florida coastline, forests of trees with a dense tangle of prop roots appear to be standing on stilts above the water. These trees, or mangroves, are not only magnificent to see, but are a key element in protecting coastlines and communities during coastal storms. Researchers at the U.S. Army Engineer Research and Development Center (ERDC) have partnered with the U.S. Army Corps of Engineers (USACE) Jacksonville District and the U.S. Naval Academy to explore the engineering value of Florida’s mangrove forests.

White River Backwater Levee Gravel Resurfacing a success
Imagine it’s pouring rain for days on end, and you live near the Mississippi River. Not a far-fetched idea for many. With rain comes rising river waters and possible flooding. To prepare for such events, monitoring the river is essential but much harder to do if the levee surface isn’t safe for travel. That’s why projects like this one are important to the people living near and around the White River Backwater Levee.

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

Snow-Covered Obstacles’ Effect on Vehicle Mobility
ABSTRACT: The Mobility in Complex Environments project used unmanned aerial systems (UAS) to identify obstacles and to provide path planning in forward operational locations. The UAS were equipped with remote-sensing devices, such as photogrammetry and lidar, to identify obstacles. The path-planning algorithms incorporated the detected obstacles to then identify the fastest and safest vehicle routes. Future algorithms should incorporate vehicle characteristics as each type of vehicle will perform differently over a given obstacle, resulting in distinctive optimal paths. This study explored the effect of snow-covered obstacles on dynamic vehicle response. Vehicle tests used an instrumented HMMWV (high mobility multipurpose wheeled vehicle) driven over obstacles with and without snow cover. Tests showed a 45% reduction in normal force variation and a 43% reduction in body acceleration associated with a 14.5 cm snow cover. To predict vehicle body acceleration and normal force response, we developed two quarter-car models: rigid terrain and deformable snow terrain quarter-car models. The simple quarter models provided reasonable agreement with the vehicle test data. We also used the models to analyze the effects of vehicle parameters, such as ground pressure, to understand the effect of snow cover on vehicle response.
