| Abstract: | A 3-D numerical tidal model to simulate M 2 tidal cu rrent field with a mobile boundary in Dingzi Bay is established in this paper. T he model is based on an international 3-D coastal ocean circulation model (ECOM model), and is modified for incorporating dry-wet grid technology to simulate flooding and ebbing in tideland. Some complex topography is taken into account, including some fords in the bay mouth and the waterway and the artificially encl osed tideland. The computed results match well with the observed ones, which imp lies that the model is capable of describing the temporal and spatial distributi on of M 2 tidal current in Dingzi Bay. |
