About this Engineering article
Wave Interaction with ‘⊥’-Type Breakwaters by S. Neelamani; R. Rajendran is a Engineering article available to read on EtoBox.
The wave transmission, reflection and energy dissipation characteristics of '-'-type breakwaters were studied using physical models. Regular and random waves in a wide range of wave heights and periods and a constant water depth were used. Five different depths of immersion (two emerged, one surface flushing and two submerged conditions) of this breakwater were selected. The coefficient of transmission, K t , and coefficient of reflection, K r , were obtained from the measurements, and the coefficient of energy loss, K l was calculated using the law of balance of energy. It was found that the wave transmission is significantly reduced with increased relative water depth, d/L, whether the vertical barrier of the breakwater is surface piercing or submerged, where 'd' is the water depth and 'L' is the wave length. The wave reflection decreases and energy loss increases with increased wave steepness, especially when the top tip of the vertical barrier of this breakwater is kept at still water level (SWL). For any incident wave climate (moderate or storm waves), the wave transmission consistently decreases and the reflection increases with increased relative depth of immersion, ⌬/d from
