Ice-covered river
Frazil slush accumulation
Estimation method
Water intake blockage
In this paper, Frazil slush variation mechanism and a method of frazil slush variation estimation on ice-covered
river are studied. This study did develop a frazil slush generation, transport and accumulation calculation model. The
continuous input values of this model are air temperature, wind velocity, sunshine duration, snowfall depth and water
level. We carried out field observation of frazil slush accumulation using the ADCP and the SWIP. It was shown that
the calculation model built by this study can reproduce the frazil slush variation of the real river. The increase of frazil
slush transport, the increase of frazil slush generation and the upstream frazil slush accumulation volume are important
values when considering frazil slush blockage of water intakes.
