A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various South jetty extensions, and (c) diversion dikes on the middle jetty. Nonstructural flood-control measures consisted of incremental sand plug removal and pilot channels. Two wave generators (70 and 80 ft long), crushed coal tracer material, Styrofoam surface floats, and an Automated Data Acquisition and Control System (ADACS) were used during model operation.

Tests were conducted in an existing 1:100-scale model of Mission Bay Harbor to determine the location and orientation of proposed structures for improving hazardous entrance conditions and reducing surge inside the harbor while minimizing impacts on surfing. The model reproduced Mission Bay Harbor, approximately 3 miles of adjacent Pacific Ocean shoreline, and sufficient offshore bathymetry to permit generation of the required test waves. Two wave generators (60 and 70 ft long), special photographic techniques, and an automated data acquisition and control system were utilized during model operation.
