Modélisation des flux et du transport de polluants en rade de Toulon

Abstract : This doctoral research aim was to study hydrodynamic processes in a semi-enclosed bay such as the Toulon bay and their importance for the dispersion of dissolved contaminants. For this study, a YfilY high resolution (100 m spatial resolution) configuration named TBAY100, based on the MITgcm ocean circulation model, was implemented. A multi-model nesting was carried out ta work at such a resolution, starting from a 1.3 km NEMO-GLAZUR64 configuration of the North-Western Mediterranean then a 400 m NEMO-NIDOR configuration of the Var coastline ta correctly force the TBAY100 boundaries. Firstly, a mathematical analysis aimed to guantify energy exchanges for a simplified system then this analysis has been extended ta the Toulon bay to better understand the exchanges at the domain open boundaries. This configuration was then validated with various observations inoludin ADCP data and driftin eolocalisable.
