Abstract:

James Island and Barren Island, in Maryland waters, are among the few remaining eastern shore islands in mid-Chesapeake Bay. Both islands are eroding at a rapid rate due to wave and storm action, as well as to relative sea level rise. These two islands are considered as potential candidate restoration sites as a beneficial use of clean dredged material from the Baltimore Harbor and Channels Federal Navigation Project. The island restoration project requires the construction of protective dikes to contain the dredged material. The restoration work should provide efficient protection to the existing islands, shelter sandy beaches and the shoreline from severe erosion, and improve water quality and surrounding environment for submerged aquatic vegetation. This report describes establishment and operation of a suite of numerical modes to evaluate alternative designs as an initial study for restoration and modification of James Island and Barren Island. The predicted wave climate along the mainland shore was also estimated for the alternatives. Both typical and storm hydrodynamic conditions were assessed. In support of the numerical modeling, sediment samples were taken and bathymetric surveys made in key areas, together with assemblage of relevant data sets such as aerial photographs of the shoreline, wind, and presence and vulnerability of submerged aquatic vegetation. Data from the modeling and other data sets assembled and collected were compiled on a DVD.
