• 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 ...
    • 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 ...
