抄録

The cold region river forms a large quantity of frazil slush during the winter period. Frazil slush often causes the clogging of the intake structure at water-power plant. So we developed the ice control structure, it is proved that the installation of the structure prevents the trouble of the intake structure. In the present report, we describe the relation between the growth of the ic e dam and water temperature, and frazil slush accumulation is proved to depend on the installation of the ice control structure.
