linear, but in fact they are not, for example, in an experiment with extremely strong
wind (τ = 0.8 N/m

Model 2: Two layers of constant density and eddy viscosity, ρ 1 < ρ 2 , μ 1 ≥ μ 2
Schematic illustrating settings and notation for this model is shown in Fig. 8. Now
we deal with two layers, each characterized by constant density (that of the upper
layer lower) and eddy viscosity (that of the upper layer higher). The notation used is
similar to that of Model 1, except that subscripts 1 and 2 refer to the variables
pertaining to the upper and the lower levels, and the depth of the interface between
them is ζ x
ð Þ.
