Abstract

Abstract

This study analyzed 42 surface sediment samples and hydrological data observed in Aprial,2007 in the Cu Lao Cau Bay. The obtained data,combined with the Gao-Collins Grain Size Trend Analysis Model (GSTA model),were used to infer the characteristics and transportation trend of sarface sediment in the Cu Lao Cau Bay,Vietnam. The results suggested that the surface sediments were mainly composed of coarse particles. Under the influences of the tidal currents and waves,the particles were coarse in the central and western part of the Bay,and fine in the eastern part. In the western part of the Bay,the sediments were transported from southwest into the Bay along the coast. In the central part of the Bay,the sediments were transported from nearshore to offshore. In the eastern part of the Bay,the sediments were transported from northeast to the southwest. A convergent area of sediments was formed by the sediment from the western and eastern part of the Bay,and then they moved westward under the influence of residual currents. The surface sediment movement was mainly induced by the superimposed effect of wave and tidal current,of which the sediment was left by wave and transported by the tidal current. The coastline of the Cu Lao Cau Bay is being eroded under the influence of wave (a main factor),and it generally takes on a tendency of moving backward.
