3 Basics of Nonhydrostatic Modelling
Fig. 3.15 Exercise 4: Snapshots of the density distribution (shading and contours) at selected times
of the simulation
Fig. 3.16 Variation of Exercise 4. Initial density field and bathymetry
pair, sometimes called a “mushroom” (Fig. 3.17). Notice that a fraction of dense
water flows back downward on the ramp.
Surely, neither the initial density distribution nor our bottom topography can be
found in nature, but it is fun to create such fictional scenarios, isn’t it? When I
showed the GIF animation of the results in the classroom, students asked whether
I believed these results were realistic. Well, we really can’t tell without any means
of comparison with the real situation, can we? Nevertheless, the author is confident
that laboratory-based experiments would show similar results.
