Abstract

It is essential to keep the clearance between the dock surface and the ships within the allowable limits to ensure easy access and serviceability. This is hard to achieve in locations with high tidal range. Using docks that can move in the vertical direction according to variation in water level is looking attractive, especially if the dock can serve as a breakwater at the same time. This paper introduces a simplified analytical approach to meet these requirements. The theory introduced predicts the wave height and water particle velocity in the leeward of the dock. The dimensions of the dock could be changed to obtain the suitable combination of both the wave height and-water particle velocity to fulfill the functionality of the harbor and minimizing the environmental impact resulting from the existence of the dock. The model eliminates the use of the variational principle and is bar—ad on mass and energy flux.
