Experiment on Density Interflow Intruding into Body of Two Layer Stratified Environment

The experiments on the density interflow intruding into the body of two layer stratified
environment. The fresh water is used for the water of the upper layer. The saline water
is used for the water of the lower layer. The travel speed of the front and the maximum
thickness are measured in the experiment. In the case that the relative density difference
of the two layer is small, the travel speed is small and the maximum thickness of the
interflow is large. On the contrary, in the case that the relative density difference is
large, the travel speed is large and the maximum thickness of the interflow is small.
The experimental results of the travel speed are compared with the theoretical equation
found by Kao. It is found that the experimental data are larger side of Kao�fs equation.
The reasons may be the effect of the mixing of the inflow water and surrounding water, the
viscosity of the water and the existence of the mixing zone between the two layers.
