抄録

The present paper is composed of the field measurement in Hiji river estuary and the numerical simulation for suspended solid. In the field measurement, the turbidity maximum was not able to confirm. It was the reason that the rate of discharge due to rainfall is much during the measured period. The breakage of aggregate is modeled, that is, when the diameter of the aggregate is larger than the micro-scale by Kolmogorov and the drag force acted to the aggregate excesses the critical value, the aggregate splits into two equal fragments. In the numerical analysis, the temporal variation of suspended solid concentration agrees well with the measured results.
