The basic principle involved in the design of berm breakwater is provision of a wide berm at or around the water level with smaller size stones in the armour, which are allowed to move till an equilibrium slope is achieved. This paper presents the results of experimental studies conducted on the wave run-up, run-down characteristics of berm breakwater using concrete cube as artificial armour unit. The experiments were conducted under following conditions, berm width = 0.45m, water depths 0.37, 0.40 & 0.43m, breakwater slope 1:1.5. The weight of concrete cube is 79.5 gm. The wave heights used in the experiments are 0.10, 0.12, 0.14, and 0.16 m and wave periods are 1.6 and 2.0 sec. From the experimental study it is found that the run-up is more for longer period waves in comparison with the shorter period waves. With the increase in deep water wave steepness the run-up and run-down was found to decrease for all the water depths considered. The run-up values (Ru/Ho) vary from 0.52 to 1.08. The range of run-down values (Rd/Ho) varies from 0.45 to 0.88. In berm breakwater the run-up and run-down values were reduced by 35.91% and 23.81% when compared with conventional rubble mound breakwater.
