ABSTRACT
All forms of life on earth are immersed in natural fluids, such as the air in the atmosphere and the water in surface and underground systems. The knowledge of natural fluids motions is therefore very important and lead to the implementation of a new discipline, termed Environmental Fluid Mechanics (EFM). EFM is the scientific study of naturally occurring fluid flows of air and water on our planet Earth, especially of those flows that affect the environmental quality of air and water.
