Abstract

 This study aims to clarify the ice jam phenomenon around piers. We conducted an ice jam experiment which used mixed real ice with ice sheet and frazil slush. In order to clarify the effect of frazil slush, the experimental results show that ice velocity, number of ice, floods area variations, water level variations. In the case of containing frazil slush, they accumulate underneath the flowing ice sheet, sticking to each other and flowing down as large blocks. And, Ice sheet velocity is slowed down because the shape resistance increases. In the case of containing frazil slush, the ice flows downstream as large ice blocks. When ice jam is generated, the upstream floods area velocity increases and floods rapidly.
