 note = {The behavior of the river ice and the frazil ice were important for study of the ice-covered river. However, it was difficult to investigate the river ice and frazil ice thickness and behavior on the ice-covered river. We enabled to measure the ice layer thickness using the snow depth meter, the depth sounder, and SWIP(Shallow Water Ice Profiler). And we could investigate time series behavior of the river ice internal structure that was snowfalls, the river ice and the frazil ice. Especially, we could understand the behavior of the suspended frazil ice that existed in water by using SWIP. As a result, the suspended frazil ice would originate in the weather condition such as the snowfalls and temperature. And at the Break-up, the suspended frazil ice would exist by high concentration from the upper stream transportation by the rise of the water temperature. This study presented the time series measurement technique of thickness and behavior of the river ice and the frazil ice.},
