The Committee on Tidal Hydraulics is a permanent committee providing consulting to the U.S. Army Corps of Engineers on engineering and scientific issues in tidal and related waters. The CTH meets at the request of a Corps of Engineers official, usually a District Engineer, who invites the committee to review one or more District projects and provide advice on those projects. The committee also assists districts with independent technical reviews, workshops, and other needs.

The committee consists of tidal hydraulics experts from Corps of Engineers offices nationwide. It investigates, advises, and reports in the area of tidal hydraulic engineering and science, including aspects such as: sedimentation; hurricane and tidal surges; estuarine circulation; and salt water intrusion


  • Maintain a continuing evaluation of the state-of-the-art in tidal and related water hydraulics.
  • Determine problem areas and recommend studies, investigations, and research designed to provide improved techniques and guidance.
  • Disseminate pertinent information.
  • Render consulting service on specific problems as requested by various elements of USACE.
  • Participate in development of guidance.
