Figure 5.2 Natural periods of marine structures and wave excitation periods.
With this background in mind, the present chapter addresses characteristic features of wave
loading and associated dynamic load effects, primarily for marine civil engineering structures.
5.2 WAVE AND CURRENT CONDITIONS
5.2.1 General
Surface water waves may be generated by wind, tidal bore, earthquake or landslides. Internal
water waves may be generated at a boundary between water layers of different densities, and
are not likely to occur together with wind generated surface waves.
The focus here is on oscillatory wind generated surface waves. Waves developed in an area
may endure after the wind ceases and propagate to another area–as
