Study of characteristics and transport pattern of surface sediment during dry seasons in Huangmao Estuary
摘要
Abstract
Based on the grain size analysis of surface sediments sampled in the Huangmao Estuary in January 2010 and in April 2011, the characteristics of the surface sediments in the Huangmao Estuary are studied and the surface sediments transport pattern is scrutinized employing the grain size trend analysis. The results indicate that the surface sediments are mainly muddy silt, poorly sorted, symmetrical, and mesokurtic. From the head of the estuary to the north of inner slope of the sand bar, the surface sediment is transported downstream; from the inner slope to the north of Damang island, the surface sediment is transported upstream; from Da-mang island to the outlets of the estuary, three types of sediment transport exist; among which, to the west of Damang island and Hebao island, in the middle outlet, the surface sediment is transported from south to north, further upstream it is from southeast to northwest; to the east of Damang island and Hebao island, it is transported from north to south. The surface sediment is generally deflected to the west. The spatial change and transport pattern of the surface sediment are well in agreement with the hydrodynamic change in the Huangmao Estuary.关键词
