Final Report [Apra Harbor, Guam]

Contract NOy-12561 was initiated 28 June 1945 for the purpose of conducting hydraulic model experiments to guide the extensive harbor improvements then in process and planned for, at Apra Harbor, Guam, M. I. The contract was continued through change orders and finally terminated on 30 November 1954. The Apra Harbor investigation was completed at the end of 1948, and during the following contract period activity was directed along the lines of basic investigations of wave phenomena as they affect harbors and harbor structures. The program of the Laboratory was formulated and directed by Robert T. Knapp, Professor of Hydraulics, during the Apra Harbor studies and those immediately following. During this time laboratory facilities were designed and procured and the general program, which was followed by the project until its completion, was delineated. Dr. Warren O. Wagner was supervisor of the project during most of the Apra Harbor study. From the spring of 1949 until the termination of the contract, the project was supervised by Mr. John H. Carr. In the following sections of this report, the aim and procedure of the several investigations are outlined, and the principal results summarized.
