| 英文摘要 | Artificial reefing (AR) is important for restoring coastal fishery resources with the better ecological environment of the coastal water. However,little is known of the local hydrodynamic characteristics. Based on an over-6-month in-situ observation with mooring in a seabed platform, we studied the tidal spectra,tidal current,and tidal residual current using low-pass filtering and harmonic analysis. The results show that the tide was an irregular semi-diurnal tide with a tidal form of 0.98, the mean tidal range of 0.95m,and the maximum possible tidal range of 2.25m. The tidal current signal was also irregular semi-diurnal dominated by M_2 component. The motion type of the principal tidal current was inclined to reciprocate with a maximum tidal velocity in direction of NNE-SSW. The magnitude of velocity significantly reduced 30% from the surface to bottom. Meanwhile,the tidal flow tended to clockwise. The residual current was very weak and the Euler and the Stokes residual current was 1.35cm/s and 1.41cm/s,respectively, in direction of SEE, showing a landward transport. The Lagrangian residual current was 2.76cm/s, in direction of SEE. The hydrodynamic characteristics were closely related to bottom friction increase and retardation effects due to artificial reefs. The bottom temperature varied frequently in the semi-diurnal and diurnal period. In addition,seasonal variation was notable. In winter, the signal of the diurnal period was dominant due to the strong vertical mixing. The vertical mixing affected by spring wind, resulting in bottom turbidity variation. Therefore,we shall study AR on a small scale to understand the bottom boundary layer dynamics and on a large scale the coastal current system. |
