Optmization of Breakwater Lengths in Relation to Wave Penetration
In general, breakwaters are high cost items in port construction. Minimum length together with adequate protection of port and operations is beneficial to capital investment. A systematic approach is required to balance all factors in the economic optimization process. Many of the aspects involved in the evaluation of port layouts with respect to breakwater length are reviewed. The length of the breakwater is of extreme importance as it provides protection of vessels at berth from wave action. Wave penetration into the port basin was studied by means of numerical and physical models. With the numerical models at a network of points inside the port, the effects of wave refraction and diffraction around breakwater heads as well as the influence of wave reflection were computed. In the hydraulic models, actual wave penetration was defined. To this effect, wave heights were measured at a number of selected points. The results of both approaches to the problem were correlated in order to obtain the highest degree of accuracy. From these results, further studies of the operational conditions for cargo handling and vessel behavior inside the port can be made.
