FINE SEDIMENT TRANSPORT IN STORM EVENT THE HUANGHUA EXPERIENCE

摘要

Remote sensing analysis, field measurements, three-dimensional numerical modeling and indoor wave flume tests are utilized to study the fine sediment transport in storm event in Port Huanghua. Results show that a fine sediment beach like Huanghua, which has less sticky composition, posts greater risks for channel deposition when comparing with sand and muddy coast. The reasons include a decreased wave energy dissipation due to bottom effect when comparing with muddy coast, and a lower critical shear stress when comparing with sand coast. For this type of beach, wave is the primary force to stir up sediments. Remote sensing and 2D horizontal numerical modeling need to be used with caution due to their lack of vertical resolution.
