  • Simanesew, Abushet; Krogstad, Harald E; Trulsen, Karsten; Nieto Borge, Jose Carlos (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The properties of directional distributions in ocean wave spectra are studied, with an emphasis on sea states with bimodal directional distributions in the high-frequency tails of single-peaked wave systems. A peak-splitting ...
  • Simanesew, Abushet; Krogstad, Harald E; Trulsen, Karsten; Nieto Borge, Jose Carlos (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    The paper discusses the development of a frequency dependent directional spread from an initial condition of frequency-independence. The study applies basin directional measurements from the Maritime Research Institute ...
  • Taklo, Tore Magnus Arnesen; Trulsen, Karsten; Gramstad, Odin; Krogstad, Harald E; Jensen, Atle (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
    We report laboratory experiments and numerical simulations of the Zakharov equation, designed to have sufficient resolution in space and time to measure the dispersion relation for random surface gravity waves. The experiments ...
  • Taklo, Tore Magnus Arnesen; Trulsen, Karsten; Krogstad, Harald E; Nieto Borge, Jose Carlos (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Using a nonlinear evolution equation we examine the dependence of the dispersion of directional surface gravity waves on the Benjamin–Feir index (BFI) and crest length. A parameter for describing the deviation between the ...
  • Simanesew, Abushet; Trulsen, Karsten; Krogstad, Harald E; Nieto Borge, José Carlos (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    We have employed laboratory and numerical experiments in order to investigate propagation of waves in both long and short-crested wave fields in deep water. For long-crested waves with steepness, ϵ = kcac = 0.1 (a fairly ...
