  • Combined USACE, ERDC teams seek to wipe out aquatic nuisance

    The U.S. Fish and Wildlife Service lists hydrilla – or water thyme – as the “world’s worst invasive aquatic plant,” and one specific strain of hydrilla is drawing the attention of federal agencies, including the U.S. Army Engineer Research and Development Center (ERDC). Connecticut River hydrilla has proven resistant to traditional control efforts and is threatening to take over New England’s Connecticut River.
  • FUNWAVE Model is a Feasible Solution for Vessel Wake Issues

    FUNWAVE, a numerical wave model that simulates ocean surface wave propagation in shallow and intermediate water was developed and updated by ERDC and released in 1998. It can be used to model complex coastal processes, such as tsunami waves, coastal inundation, wave propagation and surf zone-scale optical properties.
  • Techniques developed to advance concrete construction in frigid environments

    U.S. Army Engineer Research and Development Center (ERDC) researchers have developed Additive Regulated Concrete for Thermally Extreme Conditions – or ARCTEC – to enable the use of commonly available concrete additives as alternative freeze-protection in cold conditions. ARCTEC builds upon pioneering work performed at ERDC over the last several decades, with the goal of improving the user-friendliness, economy and utility of the technology.
  • From Antiquated to Automated: USACE wetland delineation tool helps revolutionize regulatory process

    According to the Environmental Protection Agency, United States has lost more than half of its wetlands since the 1600s, and approximately 35 percent of the world’s wetlands were lost between 1970 and 2015. To protect against further impairment of wetlands and the essential functions they provide, the U.S. established a policy of "no net loss" of wetlands, as well as procedures to ensure responsible management of wetland resources.
