COUPLING OF HYDRODYNAMIC AND WAVE MODELS CASE STUDY FOR WINTER STORM SURGE IN BOHAI SEA

[摘要] A hydrodynamic and wave coupled model, ADCIRC+SWAN, is used to simulate winter storm during 8th, Oct 2003 to 14th, Oct 2003 in Bohai Sea. Effect of wave radiation Stress on the current and the elevation is studied through numerical test. The sea surface elevation can increase over 2.0m in the Bohai Bay and Laizhou Bay, and decrease in the same order in Liaodong Bay under the effect of strong north wind. The currents change in a wide range and large scale counterclockwise circulations occur in the area. The evaluation induced by wave radiation stress can reach 0.10m to 0.20m and the current can reach 0.20m/s to 0.40m/s near the coastline during the winter storm.
