    • Flow over a rounded backward-facing step, comparing a z-coordinate model and a σ-coordinate model 

      Rygg, Kristin; Alendal, Guttorm; Haugan, Peter Mosby (Peer reviewed; Journal article, 2011)
      Homogeneous, nonrotating flow over a backward-facing rounded step is simulated using the 2D vertical version of two general circulation models, a z-coordinate model—the Massachusetts Institute of Technology general circulation ...

    • The importance of wind forcing in fjord wave modelling 

      Christakos, Konstantinos; Furevik, Birgitte Rugaard; Aarnes, Ole Johan; Breivik, Øyvind; Tuomi, Laura; Byrkjedal, Øyvind (Peer reviewed; Journal article, 2019-12-03)
      Accurate predictions of surface ocean waves in coastal areas are important for a number of marine activities. In complex coastlines with islands and fjords, the quality of wind forcing significantly affects the results. ...

    • Numerical modelling of organic waste dispersion from fjord located fish farms 

      Ali, Alfatih Mohammed A.; Thiem, Øyvind; Berntsen, Jarle (Peer reviewed; Journal article, 2011-04-21)
      In this study, a three-dimensional particle tracking model coupled to a terrain following ocean model is used to investigate the dispersion and the deposition of fish farm particulate matter (uneaten food and fish faeces) ...

    • Sea-state contributions to sea-level variability in the European Seas 

      Bonaduce, Antonio; Staneva, Joanna; Grayek, Sebastian; Bidlot, Jean-Raymond; Breivik, Øyvind (Journal article; Peer reviewed, 2020)
      The contribution of sea-state-induced processes to sea-level variability is investigated through ocean-wave coupled simulations. These experiments are performed with a high-resolution configuration of the Geestacht COAstal ...

    • Super-resolution data assimilation 

      Barthelemy, Sebastien Jean-Claude; Brajard, Julien; Bertino, Laurent; Counillon, Francois Stephane (Journal article; Peer reviewed, 2022)
      Increasing model resolution can improve the performance of a data assimilation system because it reduces model error, the system can more optimally use high-resolution observations, and with an ensemble data assimilation ...

    • Turbulence structure in the upper ocean: a comparative study of observations and modeling 

      Paskyabi, Mostafa Bakhoday; Fer, Ilker (Peer reviewed; Journal article, 2014-04)
      Observations of turbulent dissipation rates measured by two independent instruments are compared with numerical model runs to investigate the injection of turbulence generated by sea surface gravity waves. The nearsurface ...

    • Turbulence-particle interactions under surface gravity waves 

      Bakhoday Paskyabi, Mostafa (Peer reviewed; Journal article, 2016)
      The dispersion and transport of single inertial particles through an oscillatory turbulent aquatic environment are examined numerically by a Lagrangian particle tracking model using a series of idealised test cases. The ...
