This memorandum is a comprehensive report of a hydraulic model study of wave action at the carrier pier and in the seaplane lagoon, and of shoaling in the dredged turning basin of the U. S. Naval Air Station, Alameda, California. The investigation was performed by the Waterways Experiment Station at the request of the Chief of the Bureau of Yards and Docks, Navy Department, during the period from November 1942 to February 1945. The Naval Air Station at Alameda is provided with facilities for both land- and sea-type aircraft and for naval ships of various types Its location, west of the City of Alameda along an unprotected section of the shore line of San Francisco Bay, exposes the docking facilities to local storm waves from the southeast to southwest directions. There is also considerable shoaling in the dredged turning basin (located at the entrance to the lagoon and pier) from deposition of silt material. The purpose of the model study was to investigate proposed plans for protecting the carrier pier and seaplane lagoon from storm waves, and for eliminating or reducing the shoaling in the turning basin. These plans consisted of various locations and alignments of a protecting breakwater, sizes and locations of navigation openings in the breakwater, lengths of north-south spur breakwaters on both sides of the navigation opening, and top elevations of the breakwater.
