Selection of Optimum Plan for Reduction of Wave Action in Marina Del Rey, Venice, California: Hydraulic Model Investigation

摘要

A hydraulic model investigation of the wave-action problems in Marina del Rey, a small-craft harbor consisting of a 2-mile-long channel and eight lateral basins, was conducted to develop and test an optimum plan of improvement that would effectively reduce wave heights within the harbor to a satisfactory level (i.e., heights of 2 ft or less). The 1:75-scale model, molded in concrete, reproduced the entire harbor and enough of adjacent Santa Monica Bay to allow propagation of the required test waves. A 40-ft-long wave machine and electrical wave-height measuring and recording apparatus were utilized in model operation. Base tests were conducted with existing prototype conditions installed in the model. Results of tests involving various improvement plans were compared with base-test results to determine the effectiveness of the respective plans. (Author)
