Abstract

A reliable modelling of hydrodynamics and transport of substances in water basins, such as lakes, harbors
and estuaries, is typically a difficult task because of the intermittent external forcing (mainly wind), the
internal stratification (usually due to the vertical distribution of temperature and/or salinity), the possible
onset of internal waves, and the complex diffusion processes that characterize these environments. In
particular, simulating the mixing associated with turbulence requires suitable models, which vary from very
simple algebraic empirical closure for the eddy diffusivity, to more elaborate systems of differential
equations for the transport of the turbulence properties, up to complex and computational demanding
Large Eddy Simulations that are nowadays becoming a viable option also to study real problems. This
course aims at providing the basic background on the boundary conditions and the physical processes in
lakes, estuaries and semi-enclosed basins as well as the modelling tools to understand and exploit the
recent developments in this field. The course is intended for researchers and practitioners willing to
become mature and aware users of the commercial software available in the environmental fluid dynamics
engineering community.
