Lake Geneva: A natural laboratory for transport processes

Dynamics in Lake Geneva are analysed in view of recent observational and numerical advances. The classical linear internal wave view of Lake Dynamics is complemented by the description of near-shore, vortex-like nonlinear motions. The development of these structures is linked to bottom friction. Preliminary results from Lagrangian particle tracking simulations suggest that their existence is important for the transport of scalars within the lake.
