Abstract

A step in the path of invention is always accompanied by a wish for optimization. Similarly , breakwaters which mainly aims at breaking up of the waves for providing tranquility conditions in their optimizing phase has lead to the evolution of Berm breakwaters. The design philosophy of berm breakwaters aims at optimizing the structure not only with respect to wave load but also possible yield from an armor stone quarry, which can be characterized as supply – based design. In the present study the static stability of the berm breakwater model with berm width of 60cm and 20% reduced armor weight than that of conventional mound breakwater formula has been tested. The variations of non-dimensional run up values (Ru/Ho) and the rundown values (Rd/Ho) with deep-water wave steepness (Ho/gT2) are brought under the study area. A decrease in wave run up and run down with increase in wave steepness has been observed.
