Abstract

Both the concentration of suspended-load and the current velocity have been measured continuously in the surf zone. In order to measure the concentration of the suspended-load in the surf zone, a optical densitometer has been developed. The current velocity was measured by means of electromagnetic current meters. According to data analyses, the mean concentration of the suspended-load is high in the final breaking zone and in the breaker zone. In the final breaking zone, the concentration fluctuates with the period of the incident waves. On the other hand, it fluctuates with the period longer than 40 seconds in the breaker zone and it becomes high when the current is offshoreward. The directions of the net transport of the suspendedload in the middle layer in and near the surf zone are offshoreward.
