N2 - In this paper, we study the diffusion of a water release into an
important real water basin, Lake Garda in northern Italy, coupling a
variety of models from hydrodynamics (full Navier-Stokes for the
motion of water) to statistics (for the modelling of rain inflow and the
time-periodic wind motion on the surface). Using a recent digital
bathymetry, we are able to present some novel forecasts of water
dynamics, in the presence of an uncommon water release by river
Adige into Lake Garda, necessary to prevent flood situations in case of
heavy rainfall, and taking into account common inflows, wind speed
on the surface and friction on the bottom. The output shows the
trajectories of the released particles, which are typically much colder
than the existing ones, and may help to individuate critical sites and
shores.
