閉鎖性湾域の海水交換に関する実験的研究

抄録

The tidal flow and exchange processes between rectangular-shaped pocket and tidal channel was investigated experimentally using a flow visualization technique. The spatial structure of the tidal flow field was found to exhibit marked variation through the course of the tidal cycle, with clear evidence of transient eddies and flow separation at the corner of the pocket. Such variation has a strong connection with the tidal exchange through the entrance of the pocket. A simple analysis of tidal exchange was presented and calibrated by experiments.
