Damage Value of Wave Breaker Protection Coating That was Placed by Organized and Raised Due to Wave Attack
Keywords:damage, layer of protection, waves, arranged, scrambled.
Protective layer of crushed stone material has been widely used in flexible breakwaters to protect the coast from damage. The formulation of the problem in this study is: does crushed stone material as a protective layer of breakwater which is placed in an arranged manner will give a smaller damage value than that which is placed in a random way when it gets attacked by waves? The purpose of this study was to determine the amount of damage to the protective layer of the breakwater which was placed in an arranged and randomized manner due to wave attack. For this purpose a model of the sloping side breakwater structure is made. The main tool used in this research is a wave channel equipped with a wave generator, a wave height measuring device, a computer equipped with a wave synthesizer program. The protection layer stability test was carried out with a wave attack duration of 100 minutes, at a depth of water in front of the leg of the breakwater of 13 cm on the model scale. The damage to the protective layer is calculated based on the ratio of the protective layer material that has moved from its place to the material affected by the wave attack. The results showed that the protected layer of crushed stone which was placed in an arranged manner had a smaller damage value when compared to the protected layer of crushed stone which was placed randomly at the same wave height attack
