Harbor Development Study Interim Report January - July, 1952

Abstract

This report summarizes experimental and analytical work conducted in the Laboratory during the first half of 1952. During this period the first task of the current change order, the preparation of a manual of harbor design, was also accomplished. Sections II and III of this report describe work done in connection with the second task assignment - the obtaining of further information concerning wave disturbances in harbors. The experimental part of this study was terminated for lack of time before positive results could be obtained. The study was nonetheless interesting and valuable since it pointed out the importance of further investigation of the stability of standing wave patterns in closed basins. Sections IV and V describe initial phases of two-and three-dimensional studies of scour, a program undertaken in accordance with the general provisions of the third task assignment of the change order. These studies are to be continued until the termination of the current contract period, and have been proposed for further study in the pending contract extension proposal.
