Tests were conducted in a 2-ft-wide flume to aid in designing a three-dimensional tsunami model of Crescent City Harbor, Calif. The three-dimensional model will be used to investigate the technical feasibility of a levee-type barrier to protect the city from attack by tsunamis. The present investigation was conducted to determine (a.) how runup of tsunami waves is affected by model-scale distortion and change in wave period and (b.) an approximate crown elevation needed to prevent all but minor overtopping of the tsunami barrier. This information was needed to allow preparation of a preliminary estimate of the cost of the proposed barrier. The test results showed that a distortion ratio of three could be used in construction of the three-dimensional tsunami model. The two-dimensional tests indicated that a barrier crown elevation of +22 ft mllw would not be overtopped by the design wave. This height, which was selected from two-dimensional flume tests for preliminary design purposes, cannot be considered final until similar tests are conducted in a three- dimensional tsunami model. Design features of a three-dimensional model to study tsunamis at Crescent City Harbor, Calif., are presented. The selected linear scales are 1:125 vertical and 1:375 horizontal, and the model will reproduce approximately 19.2 square miles in the prototype.
