Özet:

Berm breakwaters can be alternatives to the conventional rubble mound breakwaters as they can be designed for high stability, low wave overtopping rates and economic viability. However, fully and partly reshaped berm brekwaters require optimization of design and construction parameters which requires physical model experiments. In this study, Ordu-Giresun Airport Berm Breakwater and 4 alternative crosssections of fully and partly reshaped berm breakwaters were tested for stability and wave overtopping. Analyses of all sections were executed to compare their performances. The experiments were conducted in the Coastal and Harbor Engineering Laboratory of the Middle East Technical University, Civil Engineering Department. Models were constructed using different ranges of stone sizes with a model scale of 1:32.86. It was concluded that both fully reshaped and partly reshaped cross sections can be designed to provide the specifications of the project. In the final part of study, cost analyses of the sections we re carried out using two approaches: (a) unit prices listed by the government, (b) the implementation of the contractor. It is shown that construction of the alternative berm breakwaters to Ordu Giresun Airport that ensures stability and wave overtopping conditions could be more economical.
