    • Combining Barotropic and Baroclinic Simplified Models for Drift Trajectory Predictions 

      Beiser, Florian; Holm, Håvard Heitlo; Sætra, Martin Lilleeng; Kristensen, Nils Melsom; Christensen, Kai Håkon (Journal article, 2024)
      The shallow-water equations are often used as a classical simplified ocean model for barotropic ocean dynamics. The same equations can also be used to model simplified baroclinic dynamics through the reduced-gravity model. ...

    • Evaluation of selected finite-difference and finite-volume approaches to rotational shallow-water flow 

      Holm, Håvard Heitlo; Brodtkorb, André R.; Brostrøm, Gøran; Christensen, Kai Håkon; Sætra, Martin Lilleeng (Journal article; Peer reviewed, 2020)
      The shallow-water equations in a rotating frame of reference are important for capturing geophysical flows in the ocean. In this paper, we examine and compare two traditional finite-difference schemes and two modern finite-volume ...
