    ERDC’s Environmental Lab publishes first-of-its-kind National Ordinary High Water Mark manual

    The U.S. Army Engineer Research and Development Center (ERDC) Environmental Laboratory (EL) recently published a groundbreaking technical guide geared toward identifying Ordinary High Water Marks (OHWM) across the nation.

  • January

    The National Technical Committee for Ordinary High Watermarks (OHWM), made up of researchers from the U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL), the Environmental Protection Agency, regulators from the U.S. Army Corps of Engineers and other academic institutions, stand in front of a waterfall following a field test of an interim OHWM identification data sheet.

    ERDC Releases New Data Sheet for Identifying Ordinary High Watermarks

    For 10 years, the U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) has  led research on the development of a national manual and data sheet to identify the Ordinary High Water Mark (OHWM) across the United States. The national manual was released as an interim draft and describes the OHWM, which is used to define the boundaries of aquatic features for a variety of federal, state and local regulatory purposes.

    The aerial drone is a new means of capturing these measurements, and the U.S. Coast Guard has also deployed traditional ground sensors to compare with the readings from the aerial drone. CRREL is one of the few federal agencies with the knowledge, permissions, licenses and facilities to accommodate in situ burns.

    CRREL tests new ways to measure smoke density

    CRREL partners with the U.S. Coast Guard's Research and Development Center and the Environmental Protection Agency to test an aerial drone to determine how effective the device is for measuring air quality and environmental impact of burning oil on water. The aerial drone is a new means of capturing these measurements, and CRREL is one of the few federal agencies with the knowledge, permissions, licenses, and facilities to accommodate in situ burns.
