Abstract

Abstract

The Yuehu is a small tidal inlet system located in the eastern Shandong Peninsula,China.In order to investigate the time-velocity asymmetric patterns of the system,hydrodynamic observations and bathymetric surveys were undertaken in the winter of 1998 and the summer of 1999.Based upon the measured tidal water levels and the calculated tidal currents,two types of additional time-velocity asymmetric patterns,other than the "flood-dominated" and "ebb-dominated" patterns,are identified:the duration of flood tide is longer(or shorter) than that of ebb tide,while the flood currents are stronger(or weaker) than the ebb currents.These patterns have been shown to be associated with the mixed and semi-diurnal dominated tides,the timing of the current velocity and water level at the entrance,the cross-section shape of the entrance channel,and the flow and circulation structures within the entrance channel.An understanding of such time-velocity asymmetric patterns is important in terms of the sediment dynamic behaviours and the artificial utilization of tidal inlets.
