Water renewal in a threshold fjord: A simulation study of submerged fresh water discharge
(Master thesis, 2018-12-15)Threshold fjords are characterized by low concentrations of oxygen in the depths of the basin, caused by weak and/or infrequent exchange of the basin water. A three-dimensional ocean model, The Bergen Ocean Model (BOM), ... -
Wave breaking in long wave models and undular bores
(Master thesis, 2015-12-18)Bores are a well known phenomena in fluid mechanics, although their occurrence in nature is relatively rare. The circumstances in which they occur is usually when a tidal swell causes a difference in surface elevation in ... -
Wave breaking in the BBM-equation

Weak solutions and convergent numerical schemes of Brenner-Navier-Stokes equations
(Research report, 2015-01-20)Lately, there has been some interest in modifications of the compressible Navier-Stokes equations to include diffusion of mass. In this paper, we investigate possible ways to add mass diffusion to the 1-D Navier-Stokes ... -
Well-posedness Issues for Nonlinear Partial Differential Equations Appearing in the Modeling of Long Water Waves
(Doctoral thesis, 2018-12-18)Modelling of wave motion in a fluid is usually based on classical systems which are obtained by the hypotheses that the flow is irrotational and the bottom is even. In such a context, the influence of vorticity is entirely ... -
Well-posedness of the fully coupled quasi-static thermo-poroelastic equations with nonlinear convective transport
(Peer reviewed; Journal article, 2019-03)This paper is concerned with the analysis of the quasi-static thermo-poroelastic model. This model is nonlinear and includes thermal effects compared to the classical quasi-static poroelastic model (also known as Biot's ... -
The Whitham Equation as a model for surface water waves
(Peer reviewed; Journal article, 2015-08)The Whitham equation was proposed as an alternate model equation for the simplified description of uni-directional wave motion at the surface of an inviscid fluid. As the Whitham equation incorporates the full linear ...
