Ice covered River
Salinity Intrusion
Experiment
This study aimed to clarify the fundamental phenomenon of salinity intrusion in ice covered river. We carried
out salinity intrusion experiment to which model ice-sheet floats on the water surface and one-dimensional two-layered
unsteady flow calculation. In this experiment, the vertical flow velocity was measured using particle image velosimetry
technique. In the experiment in which ice-sheet exists, the model ice-sheet indirectly attenuated the salinity intrusion
because Reynolds number does not become large. Shear stress was computed by having assigned the experiment data
to one-dimensional two-layered unsteady flow equation. In both ice and no-ice condition, Interface shear stress has
large influence on salinity intrusion. It was shown that the calculation model built by this study can reproduce salinity
intrusion experiment.
