Abstract: A 1:100-scale undistorted hydraulic model of Port Orford\, Oregon, and sufficient offshore area to permit generation of the required test waves was used to develop and test several plans of improvement proposed to eliminate harbor shoaling without adversely affecting wave heights at the existing pier. Improvement plans consisted of (A.) removal of portions of the existing breakwater, (B.) realignment or lengthening of the existing breakwater , and (C.) construction of new breakwater structures in the vicinity of Fort Point and Battle Rock. A 54- ft-long wave machine, electrical wave height measuring and recording apparatus, and coal and nylon tracer materials were used in the model. Tests were conducted with prebreakwater and existing breakwater conditions, and the results were compared to determine the causes and sources of harbor shoaling. Improvement plans were then tested and compared with existing prototype conditions. Of the plans tested, the optimum configuration appears to be that designated as plan 11F. NOTE: This file is large.
