Frazil particle distribution
Frazil particle distribution in ice-covered rivers is not well understood. In this paper, we carried out field observation
in northern Hokkaido. In this result, shape of frazil particle distribution is sharper than normal distribution.
and it is inclined to left side than normal distribution. Frazil particle size has two peaks, namely, high frequency size
(0.46mm) and average size (2.45mm). Relationship between frazil transport capacity and dimensionless flow strength
was investigated in an ice-covered river in Japan. Much frazil capacity has transported, because frazil particle size is
small compared with previous research. Relationship between frazil particle size and 2nd power of shear velocity was
examined. As the result, we considered transportation of frazil particle is smaller than transportation of soil particle.
