S6: Environmental Fluid Mechanics

Environmental Fluid Mechanics (EFM) is devoted to study transport, dispersion and transformation processes in natural fluid flows, from the microscale to the planetary scale. Within this scope, the subject areas are diverse and may originate from a variety of scientific and engineering disciplines: civil, mechanical and environmental engineering and environmental linking sciences, meteorology, hydrology, hydraulics, limnology and oceanography. These processes greatly affect the quality of natural ecosystems and are largely studied using also modeling techniques and software packages. For this session papers reporting observational, experimental, modeling and theoretical investigations would be welcome.

This session could tentatively cover the following topics:

• Modelling of flux exchanges between non-homogeneous surfaces and atmosphere
• Diffusion, turbulent dispersion and mixing in natural waters
• Contaminants transport in surface and subsurface waters
• Modelling of transport of water and chemicals in the soil
• Modelling of planetary boundary layer land surface processes
• Modelling of planetary boundary climatic change and future state in agriculture and forestry
• Exchange processes at the air/water interface
• Water-sediments interactions in natural waters
• Uncertainties in environmental modelling and occurrence of deterministic chaos
• Predicting the occurrence of plant diseases
• Turbulent jet and plumes
• Two-phase and multiphase flows
