THE ADVANTAGES OF MULTILAYER BERM BREAKWATERS

Berm breakwaters have basically developed in two directions. On one hand are the structures built using a homogenous berm, usually of one stone class, that areallowed to reshape, sometimes referred as dynamic berm breakwaters. On the other hand are the more stable structures with steep upper and lower slopes, built ofseveral stone classes, where only a few stones on the berm are allowed to move. These structures have been referred to as Multilayer type berm breakwaters or well known as Icelandic berm breakwaters. In this study, homogenous and multilayer Berm Breakwaters are compared regarding to technical and commercial parameters in two case studies. These case studies include construction of breakwater and shore protection of Shahid Beheshti Port locates in Chabahar, south east of Iran.
