Abstract : The discharge characteristics of the navigation opening (base width of 1500 ft) in the proposed hurricane barrier for the East Passage of Narragansett Bay, Rhode Island, were investigated by means of both section and three-dimensional models. Two section models, reproducing the barrier at scales of 1:50 and 1:150, were used to determine the effect of approach depth, roughness of the barrier, and weir design on the discharge characteristics of the structure. A 1:150-scale, undistorted, three-dimensional model was used to determine the discharge characteristics of two weir plans for both flood and ebb flows, and the effect of the oceanside spur dike on flood-flow characteristics. Basic data are presented graphically. An analysis of data was made, and discharge equations applicable to both steady state flood and ebb flows were developed. (Author)
