Abstract : Three, 1:25-scale, undistorted models were used to simulate hurricane barriers proposed for the Wareham and Weweantic Rivers and Onset Bay in the vicinity of Wareham-Marion, Massachusetts. These structures will consist of earth-fill dikes protected by rock faces and toes and intersected by navigation openings at existing navigation channels. Discharge coefficients of the structures and the maximum velocities occurring in the vicinity of the openings were determined for headwater (ocean) and tailwater (river) elevations ranging from 0.0 to 20 ft msl and -10 to 18 ft msl, reopenings was reproduced by scaled stone in the models. The Onset Bay barrier, which will have gates to permit partial closure of the navigation opening to increase protection from hurricane surges, was investigated with the gates both open and closed.
