抄録: The changes at sea level and currents in Omura Bay are studied by field observation. Twelve observations were performed from winter to spring in 1989 and 1990. One observation period was over fifteen days. As for observing the changes at sea level, four main constituents of tide (M2, S2, Kr and Or) were analyzed by the harmonic analysis of tide using the least square method. A great part of the changes at sea level shows a very good estimate by these constituents. A change of the Seich with about 25~80 minutes period was also observed. As for observing the currents, the three components of current were discussed separately. First was the constant flow component (M0) which is a mean value of currents for the observed period. In the northern part of Omura Bay, there was a weak counter clockwise constant flow. The second was the tidal current. Four main constituents of tidal currents were analyzed by the same method employed in tide. Lastly, the residual flow was the remainder of the other components described above. The correlation between wind velocities and residual flows was analyzed. At great depth of Omura Bay, flows were observed to be 244° in a clockwise direction after 3 hours delay from wind blowing.
