Abstract: This report documents numerical wave and flow modeling for stabilizing a shallow-draft navigation channel and adjacent shorelines at Rhodes Point, located on Smith Island, MD, in the Chesapeake Bay. The U.S. Army Engineer District, Baltimore (NAB), is considering structures to protect the western entrance of the channel and reduce erosion of shorelines by stabilizing the channel. The U.S. Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), performed a numerical study to develop preliminary designs for the optimal location of structures and to determine effects of waves and hydrodynamics on the structures. The Coastal Modeling System (CMS)-Wave and CMS-Flow models were used for wave and flow modeling in the Chesapeake Bay. Numerical results indicated Alternative 1, with a shore-connected north jetty nearly normal to the north shoreline at the channel entrance and a south jetty parallel to the channel with revetment structures protecting the south shorelines, offered a cost-effective solution by reducing wave energy inside the channel and along the shores. Alternative 2 with two parallel jetties provided similar wave energy reduction in the channel and along the shorelines but showed higher currents and erosional pockets developing in the channel, which could undermine the stability of the jetties.
