WebInfragravity waves, motions with periods of nominally 0.4-4 min, are believed important to harbor oscillations, sediment transport, and other nearshore processes. A strong correlation between the energy levels of infragravity waves and swell indi- cates that infragravity waves are driven by swell (Munk [1949], Tucker [1950], and many others). WebThat is, the predicted bound infragravity wave spectrum at the offshore sensor was used instead of the observed offshore infragravity spectrum as in Figures 11-!3. For low E m (and EswF_z ... WebInstead, we show that these events were more likely resulted from the shoaling of bound infragravity waves, which is a mechanism not previously considered for extreme runup. We further present a predictive method for such extreme runup events.

WebInfragravity (hereafter IG) waves are surface ocean waves with frequencies below those of wind-generated "short waves" (typically below 0.04 Hz). Here we focus on the most common type of IG waves, those induced by the presence of groups in incident short waves.

WebNov 17, 2024 · More than three decades ago, it was noted that the ocean infragravity bound wave increasingly lags behind the forcing short-wave groups when propagating towards the shore. To date, the most recent theoretical prediction of this so-called phase lag remained a first-order approximation in terms of depth variations. Here, a new semi …

WebNov 17, 2024 · Model results reveal that infragravity waves were generated mainly through the bound wave mechanism, enhanced by the development of a phase lag with the shortwave energy envelope.

Webbound waves can dominate the infragravity band [Sand, 1982]. Bound waves also have been shown to contribute as much as 50% of the infragravity energy in pressure measurements made close to shore (within 1 km) in the Pacific Ocean in mean depths of about 10 m [Okihiro et al., 1992].
