Home→ Dock and Harbor Engineering →When a wave strikes a vertical breakwater in deep water, it is reflected back and on meeting another advancing wave of similar amplitude merges and rises vertically in a wall of water. This phenomenon is called_________________?

Which of the following structures protects the shore by trapping of littoral drift?
Assertion A : Large size stones are required in stone revetment in shore protection. Reason R : Resistance of stone to wave force is proportional to its volume and wave force is proportional to the exposed area of the stone?
