    • Bimodality of Directional Distributions in Ocean Wave Spectra: A Comparison of Data-Adaptive Estimation Techniques 

      Simanesew, Abushet; Krogstad, Harald E; Trulsen, Karsten; Nieto Borge, Jose Carlos (Journal article; 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 ...

    • Development of frequency-dependent ocean wave directional distributions 

      Simanesew, Abushet; Krogstad, Harald E; Trulsen, Karsten; Nieto Borge, Jose Carlos (Journal article; 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 ...

    • Measurement of the dispersion relation for random surface gravity waves 

      Taklo, Tore Magnus Arnesen; Trulsen, Karsten; Gramstad, Odin; Krogstad, Harald E; Jensen, Atle (Journal article; 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 ...

    • On dispersion of directional surface gravity waves 

      Taklo, Tore Magnus Arnesen; Trulsen, Karsten; Krogstad, Harald E; Nieto Borge, Jose Carlos (Journal article; 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 ...

    • Surface wave predictions in weakly nonlinear directional seas 

      Simanesew, Abushet; Trulsen, Karsten; Krogstad, Harald E; Nieto Borge, José Carlos (Journal article; 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 ...
