Abstract: This report documents numerical wave and flow modeling for evaluation of the jetties on a shallow draft navigation channel on Tangier Island, VA, located in Chesapeake Bay. Because it is heavily used by the local fishing fleet, the U.S. Army Engineer District, Norfolk (CENAO) maintains the Tangier Island boat canal. CENAO is considering the construction of structures to protect the western entrance of the channel and reduce the wave energy in the lee of the structures, and asked the U.S. Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL) to perform a numerical modeling study to investigate how waves and hydrodynamics would be affected by structures, to identify the optimal location for the structures, and to develop a preliminary structure design. The primary goal of the study was to develop a quantitative estimate of waves and wave reduction in the canal for a relative comparison of alternatives investigated and for the preliminary structural design calculations. CMS-Wave, a spectral wave model, was used to estimate waves in Chesapeake Bay and propagate waves into the entrance channel and boat canal. The numerical modeling results indicated that maximum wave energy reduction inside the canal was obtained using a dog-leg jetty connecting to the north shoreline and a spur on the south shoreline.
