“…Consequently, a large portion of the wave energy passes via the slotted portion, where, as kh rises, the wave energy is concentrated at the still water level. Their findings affirmed that a properly constructed vertical-slotted-breakwater is nominated to be utilized in ports and shore protection (George and Cho 2020).…”

 I.INTRODUCTIONOASTAL regions are highly considered within the Egyptian development plan. Accordingly, there is a great attention towards protecting and sustaining beaches so as structures from being damaged by waves. This could be achieved by the available protection measures (i.e. breakwaters, groins and seawalls. However, some of them are not efficient or economic, while others fail to achieve their required protection. Such ineffectiveness emerges from their poor placement or from their design or from the improper selection of the protecting measure itself. Moreover, conventional breakwaters (i.e.rubble mound and gravity breakwaters) building material quantity increases as the depth

“…However, the design of the model, in the form of a wall, shows it has a very small and negligible relative wall thickness (b/L) [10], making it less effective in reducing the incident wave height when the porosity of the hole (ε) and wave length (L) is large. Theoretically, the energy dissipation coefficient (K D ) of the thin wall perforated breakwater model is 0 when the porosity of the hole is 0, or 1 while the maximum is only 0.3 [11].…”

This research is conducted to examine the transmission wave and energy dissipation of a box culvert-type slotted breakwater, which is designed as a breakwater structure with a watertight wall at the top and a box culvert type hole at the bottom. The process involves physical modeling of this structure in the laboratory. The hole and wave parameters are varied to determine the breakwater performance. The results show that the transmission coefficient (KT) value is reduced as the relative hole height (hL/d) value is decreasing and the relative hole length (B/L) and wave steepness (H/L) values are increasing. The energy dissipation coefficient (KD) value increases with an increment in hL/d, H/L, and B/L but starts to decrease after reaching the maximum, which is the optimum H × B/L2 value. This optimum value is found to be 0.0034(hL/d)2.618 depending on the (hL/d) value, while the maximum KD value is recorded to be 0.70.
