A Study of Sand Waves in the Panama City, Florida, Entrance Channel
Abstract
The entrance channel to St. Andrew Bay, near Panama City, Florida, is subject to the formation of large sand waves. A study was undertaken to determine the extent of the problem, as related to navigation, and to assess possible mitigative alternatives. The inlet was originally constructed in the early 1930's and now must be dredged every 12 to 24 months as a result of the large sand waves which form in the navigation channel. The study considered structural changes to the inlet/jetty system using 'INLET,' a one-dimensional inlet flow model. Various alternatives were assessed to determine if structural modifications would help reduce sand wave sizes and/or decrease the necessary dredging frequency. Alternative dredging techniques were also investigated to identify more cost-effective methods of maintaining the sand wave prone navigation channel.
