We study a gravity current flowing down a uniform slope in a stratified or homogeneous media with rotation. Experiments performed on the large Coriolis turntable (Grenoble) are used to determine the stabilization depth of the main current, to measure the mixing and friction effects in a rotating system and to observe developments of instabilities. Experiments are used to test different turbulent mixing parameterization in numerical models used in oceanography.
