The dynamics of bottom gravity currents in a laboratory-scale, stratified-flow flume is modelled using a 3D CFD tool. Also, the dense-water intrusion along a channel with a trapezoidal cross-section is characterized hydraulically. The numerical experiments are designed to aid qualitative interpretation of the formation of density-driven, bi-directional stratified flows. The turbulence characteristics of the stratified flow are introduced to investigate the internal-flow hydraulic regimes and the interface mixing between water layers.
