A 175-scale undistorted hydraulic model of Newburyport Harbor, Massachusetts, which included the lower 5,700 ft of the Merrimack River, approximately 2,300 ft of the Atlantic coastline on each side of the harbor entrance, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed improvements with respect to riverbank erosion control, wave protection, and river flow conditions. The proposed improvements consisted of a changes in the length of the north jetty, b changes in the crown elevation of the north jetty, and c addition of groins at two locations. An 80-ft-long wave generator, a water circulating system, crushed coal tracer material, and an automated data acquisition and control system ADACS were used during model operation.
