More accurate run-up predictions require taking the directional spread and frequency spread of the wave field into account. įigure 3: Significant wave height H_ and L_0 are the offshore short waveheight and wave length, respectively. This process is frequently observed on gently sloping beaches, but seems to be a less dominant mechanism for infragravity wave generation. ![]() Fast propagating bores will grow by overtaking slower ones and thus transfer short wave energy to water motions at longer periods. Wave bores that have formed after wave breaking propagate faster onshore when they ride on the crest of an infragravity wave and slower when they ride on the trough. The bound wave mechanism is strongest on gently sloping beaches whereas the breakpoint mechanism dominates on steep beaches.Ī third mechanism that can enhance water motions with infragravity periods is the merging of wave bores in the surf zone. suggested that the importance of the two above mentioned mechanisms varies with beach slope. This forces a time-variation of the radiation stress in the surf zone, which is balanced by a time-varying wave setup, and creates energy at infragravity frequencies. The largest short waves in the group will break slightly further offshore than the smallest waves in the group. The second mechanism in which infragravity waves are formed is related to the varying breakpoint of the short-wave group in shallow water. The two wave trains form wave groups and induce a long bound wave. The merging of two wave trains of slightly different wave lengths, but the same amplitude. On the open sea/ocean these bound infragravity waves are only about a centimeter in height. This induced wave is bound to the group, and is 180 degrees out of phase. This induces a variation of the mean water level on a group scale, and results in energy that fluctuates at the same frequency as the wave group. The first mechanism that can form infragravity waves is due to the fact that the larger short waves in the short-wave group transport more momentum than the smaller waves, leading to a water level lowering under the larger waves, and a relative water level increase under the smaller waves. 2b), which is irregular in shape due to the various frequencies present in a natural wave field. This results in a wave group structure (Fig. When the waves are in phase their amplitudes are added, and when they are out of phase their amplitudes damp each other out (Fig. Their creation is linked to the presence of short-wave groups, which are formed due to the superposition of short-wave trains, with slightly different wave lengths and frequencies. ![]() Infragravity waves are indirectly formed by the wind. Their generation and transformation while travelling towards the coast will be described in more detail below, together with a brief description of their noted influence in various coastal environments. Since their first observations their presence has been observed to influence many nearshore processes varying from coastal erosion during storms, to coral reef hydrodynamics and the generation of seiche in harbors. While infragravity waves are generally small on the open ocean, close to the coast they can be up to a few meters in height and thus dominate the water motion, in particular during storms. They are indirectly formed by the wind because they receive their energy from the short sea- and swell waves, which have typical periods of 2-20s. Infragravity waves are ocean surface waves with a typical period of 25-250s (frequency of 0.004-0.04 Hz, see Fig. The relative amplitude is indicated by the curve. The forces responsible for various portions of the spectrum are shown. Figure 1: Classification of ocean waves according to wave period. ![]()
