Invasive carp species pose a significant threat to native fisheries, disrupting ecological balances, inflicting economic harm and hampering recreational activities. One effort to mitigate this threat is focused on blocking these fish from entering the Great Lakes, where they could significantly disrupt a $7-billion fishing industry. Guided by ERDC research, a series of electric barriers…

Given the aging condition and economic importance of much of the nation’s navigation infrastructure, asset managers need accurate and real-time information on the conditions of structures operating well beyond their expected design lives. However, visual inspections of structures like locks and dams are often difficult and expensive. ERDC is filling this void with a broad…

After a structural collapse disaster, the eyes of the public are intensely focused on search-and-rescue efforts. Less familiar is the work of a special team from the U.S. Army Corps of Engineers (USACE) laboring behind the scenes to ensure the safety of those efforts. The USACE Urban Search and Rescue (US&R) program deploys specially trained…

There are more than 8,000 major dams in the United States, and many of them are beyond their expected design life and require regular inspections and maintenance. The majority are embankment dams that feature outlet works structures that can be up to a half-mile long and that can be dangerous to inspect. Responding to a…

Harmful algal blooms occur in freshwater when aquatic microorganisms, called cyanobacteria, grow rapidly and sometimes release toxins that are dangerous to humans and aquatic life. Such events have been known to compromise drinking water reservoirs, disrupt recreation, shut down fisheries, and kill fish, birds and other aquatic species. And scientists largely agree that these events…

The blockage of Egypt’s Suez Canal in March shone renewed focus on just how many goods are shipped around the world and how fragile those routes can be. Given the shipping industry’s importance in the U.S., American planners must have world-class tools to prevent a comparable disaster from congesting American waterways. ERDC has operated a…

The rapid accumulation of ice creates significant challenges for U.S. military operations and civilian activities in cold environments. It hampers mobility, disrupts communication, creates power outages and degrades infrastructure. That’s why a team of ERDC researchers is conducting innovative basic research to unravel the physical processes of how ice attaches to different surfaces, paving the…
