The Stability of the roundhead of a berm breakwater under oblique wave attack

In this paper, the influence of oblique waves attack on the stabilities of a reshaping breakwater roundhead have been investigated. This research has been carried out in the wave basin of Soil Conservation & Watershed Management Research Center (SCWMRC), the Ministry of Jihad-e-Keshavarzi. Irregular waves were used in this research. The wave angles were 23 & 68-degree respectto the breakwater centerline. The wave period was 12 sec and the number of wave were 1000 and 2000. The results of the experimental tests were drawn using the nondimensional parameters, showed the significant influence of the wave height on the stability of the breakwater roundhead. Also, it has been shown that the roundhead can be divided into regions having the same damage number. therefore it is not required to cover all the regions with the same armor size, resulting in the reduction of construction expenses.
