WebbThe gravity waves generated in the Arabian Sea not only depend on the wind conditions that prevail over the area, but also on southwesterly (SW) long period swells that are propagated from the Southern Ocean (Glejin et al., 2013).The wave climate of the Arabian sea, in general, is dominated by energetic summer monsoon swell waves (Glejin et al., … Webb1 jan. 2014 · Introduction. Infragravity waves are 20–200 s motions in the ocean surface that are strongest near the shore, and may be responsible for beach (e.g. Russell, 1993) and dune (Van Thiel de Vries et al., 2007) erosion.Infragravity waves can arise from the non-linear energy transfer from < 20 s sea and swell waves. In deep water the transfer …

Webb3 juni 2024 · The character and energetics of infragravity (“IG,” 25 s < period < 250 s) and very-low frequency (“VLF,” period > 250 s) waves over coral reef flats can enhance shoreline erosion or accretion, and also govern extreme shoreline events such as runup, overwash, and flooding on coral reef-lined coasts. Here we use in situ wave … Webb4 jan. 2024 · From a design perspective, the presence of IG waves typically results in higher characteristic values of the two main parameters used to estimate qa: namely, the significant wave height and spectral wave period, both assessed at the structure toe (Van Gent, 1999; Hofland et al., 2024).

Typical short-wave … WebbInfragravity 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).
