Numerical Simulation on Sudden Siltation Induced by Winner Storm and Large Waves in Outer Channel of Huanghua Port, China

Abstract:

A multinest storm surge-wave-sediment model is applied to simulate strong storm surge caused by winter storm in Bohai Bay in Oct, 2003. The fields of current and sediment of for- and post- regulating structure are calculated to analysis the effect of regulation. The results show that the alongshore current caused by storm surge strengthen the cross-channel component and that provided the impetus conditions for sediment transport. The siltation in the outer channel of Huanghua port in the second stage is very severe. For example, the thickness of slitting sediment in the area, 3~19 kilometers (away from the entrance of port) is over 2.0 meters. While the third stage dike for debris barrier is completed, the hyper-concentrated silt-laden flow offshore could be eluded, and the maximum deposition area goes out thus the sediment siltation is reduced.
