Aquatic gravity currents through emergent vegetation
… and cooling can generate density-driven, lateral exchange flows in aquatic systems. Despite the ubiquity of wetlands and other types of aquatic canopies, few studies have examined the hydrodynamic effects of aquatic vegetation on these currents. This study investigates the dynamics of …

Variational multi-scale modeling for particle-laden gravity currents over flat and triangular wavy terrains
… proposed formulation is utilized to simulate the lock-exchange particle-laden gravity currents. In this paper, two sets of simulations based on the finite element method are conducted on the Stampede2, TACC to validate the models. Firstly, we design a simple physical case that gravity currents over …

The influence of steps topography on the behavior of density currents – a numerical study
… of depth-resolved numerical experiments with a lock-exchange setup were conducted using k-epsilon, two-dimensional and three-dimensional Large Eddy Simulation (LES) models. The results of the present study clearly indicate that compared with a constant slope bed, vertical steps, or “stair-case” …

High order hybrid discontinuous Galerkin regional ocean modelling
… diffusion and stokes equations, and the 2D lock-exchange problem. These numerical schemes are then extended for non-hydrostatic, free-surface, variable-density regional ocean dynamics. The time-splitting procedure using projection methods is derived for non-hydrostatic or hydrostatic, and …
