摘要
Abstract
In-situ measurement of suspended sediment was conducted in the coastal waters of Wendeng in May 2015.With the measured data,we calculated the concentrations of the suspended sediments in different water layers and analyzed their spatial and temporal distribution patterns.Wavelet transform was done to define the cyclicity of the suspended matter.Combined with the residual current field,the overall transport characteristics of the suspended sediment in the study area are scrutinized and sum marized.Results show that the concentration of suspended sediment has a periodic characteristic of every 6 hours,in good agreement with the regular half-day tidal current,and increases from surface to bottom.In the areas dominated by the residual flow,such as the Changhuikou area,the area near Zhangjiabu Newport breakwater and the area near the Haodangjia fishing harbor breakwater,suspended sediment transporting direction is same as the ebb direction.In the area near the Haodangjia fishing harbor,however,the suspended sediment moves following the direction flood tide.Suspended sediment transportation is in a clockwise manner in the Wuleidao Bay and the Jinghai Bay,following the ebb current.关键词
