• 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 ...
    • 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 ...
