| Abstract: | By means of FVCOM model,the tide and tidal currents in the seas adjacent to Ningbo and Zhoushan were simulated.Furthermore,the dynamic characteristics of tide were analyzed.The grid system of FVCOM model was unstructured triangle mesh,which solved the accurate fitting of complex of Ningbo and Zhoushan shoreline.Based on the property of seabed in the calculation zone, Koutitas formula was used to instead of the original calculation method of drag coefficient in FVCOM.Comparing the computed values with those tidal observatories,the improved formula proved to be reasonable and the two values are in good agreement.The computed model can be used for 3D pollutant concentration and sediment transport calculation. |
