  • ERDC researchers engage citizen scientists in data collection

    Researchers from the U.S. Army Engineer Research and Development Center (ERDC), along with the U.S. Geological Service, Marda Science and James Madison University, are engaging citizen scientists in a national SandSnap initiative to amass a spatial and temporally varying nationwide beach grain-size database.

  • ERDC mourns loss of dredging industry expert

    The dredging industry has suffered a great loss with the recent death of Timothy L. Welp, a research hydraulic engineer with the U.S. Army Engineer Research and Development Center (ERDC).

  • Using simulation tools for operational readiness in maritime and littoral operations

    Operational readiness is a term used throughout the six branches of the U.S. military. The ability of armed forces to conduct the full range of military operations, regardless of a posed threat, is contingent upon how well units are manned, equipped, trained and led. To increase readiness, researchers at the U.S. Army Engineer Research and Development Center (ERDC) have partnered with the U.S. Navy and U.S. Marine Corps on a joint venture to use ship simulation and numerical models in the planning of amphibious assaults and littoral operations.

  • USACE, James Madison University hold SandSnap event

    The U.S. Army Corps of Engineers (USACE) and James Madison University invite the public to become citizen scientists at a SandSnap event at the Jones Beach Energy and Nature Center June 5 from 10 a.m. to 2 p.m. EDT.

  • Zimmerman joins the ERDC’s Coastal, Hydraulics Laboratory

    Julia Zimmerman has joined the Coastal and Hydraulics Laboratory’s River and Estuarine Engineering Branch at the U.S. Army Engineer Research and Development Center (ERDC).

  • Cecil joins the ERDC’s Coastal, Hydraulics Laboratory

    Dr. Orie Cecil has joined the Coastal and Hydraulics Laboratory’s Hydrologic Systems Branch at the U.S. Army Engineer Research and Development Center (ERDC).

  • ERDC researchers commission full-size, semi-autonomous research vessel

    Making its way through the murky waters and swift current of the Mississippi River at the Vicksburg riverfront, the Research Vessel Martin looks like any other U.S. Army Corps of Engineers (USACE) survey boat. However, there is one major difference. The inland survey vessel has been converted into a semi-autonomous craft, making it the first of its kind for the organization.

  • ERDC’s Field Research Facility holds groundbreaking ceremony for new annex

    The U.S. Army Engineer Research and Development Center (ERDC) held a groundbreaking ceremony for a new annex building at its Field Research Facility in Duck, North Carolina, April 6, 2021. ​The $4.3-million annex will consist of laboratory and research administrative spaces to support the organization’s expanded military research mission. In collaboration with the Army’s Maneuver Center of Excellence, the Field Research Facility develops methods to protect forces, conduct forcible and early entry and transition rapidly to offensive operations.

  • 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.

  • Simulations of Shoreline Changes along the Delaware Coast

    Abstract: This technical report presents two applications of the GenCade model to simulate long-term shoreline evolution along the Delaware Coast driven by waves, inlet sediment transport, and longshore sediment transport. The simulations also include coastal protection practices such as periodic beach fills, post-storm nourishment, and sand bypassing. Two site-specific GenCade models were developed: one is for the coasts adjacent to the Indian River Inlet (IRI) and another is for Fenwick Island. In the first model, the sediment exchanges among the shoals and bars of the inlet were simulated by the Inlet Reservoir Model (IRM) in the GenCade. An inlet sediment transfer factor (γ) was derived from the IRM to quantify the capability of inlet sediment bypassing, measured by a rate of longshore sediments transferred across an inlet from the updrift side to the downdrift side. The second model for the Fenwick Island coast was validated by simulating an 11-year-long shoreline evolution driven by longshore sediment transport and periodic beach fills. Validation of the two models was achieved through evaluating statistical errors of simulations. The effects of the sand bypassing operation across the IRI and the beach fills in Fenwick Island were examined by comparing simulation results with and without those protection practices. Results of the study will benefit planning and management of coastal sediments at the sites.
