Explanation:
The knowledge of magnitude and behavior of ocean waves at site is an essential
prerequisite for almost all activities in the ocean including planning, design, construction and
operation related to harbor, coastal and structures.
The waves of major concern to a harbor engineer are generated by the action of wind.
The wind creates a disturbance in the sea which is restored to its calm equilibrium position by
the action of gravity and hence resulting waves are called wind generated gravity waves. The
height of a wave is the vertical distance between its crest and trough, the period of a wave is the
time required to complete one cycle of its oscillation, while the horizontal spread of one wave
(distance between any two points with the same phase) is called wave length. See Fig. 1.1. The
height of waves (H), in practice varies from a few cm to over 30 m while the variation in
corresponding wave period (T), is from 3 seconds to about 25 seconds. The length of a wave (L)
may range from a few meters to over a kilometer.
