Use of Site-Specific Model Data for General Breakwater Design
Abstract
The purpose of this investigation was to obtain a better understanding of why significant variations in the stability coefficient occur. Specifically, it was hoped that functional relationships could be developed between the stability coefficient and such variables as wave height, wave period, and water depth. These functional relationships would then be used as input to a n improved procedure for obtaining minimum armor unit weights required for hydraulic stability. Also, it was hoped that a link could be developed between breaking and nonbreaking wave test results. Based on results of model tests described herein, in which tetrapod, tribar, dolos, and stone armor are used on breakwater trunks and heads, it is concluded that test results are very significant in that they show tetrapod, tribar, dolos, and stone stability to be dependent on the combined effects of wave height, wave period, and water depth with minimum stability occurring at the lower values of d/L and higher values of H/d , i.e., longer wave periods in shallower water. An improved procedure for determining minimum armor unit weights was developed.
