Analysis of geomorphic characteristics and sediment source of near-shore area in Xinghua Bay
摘要
Abstract
Based on site topography survey and sediment sampling analysis in Xinghua Bay,natural conditions, sedimentary characteristics,sediment source and transport tendency were studied.The results show that the underwater sediment in the west of Shicheng Island is mainly consisted of clayey silt,and the sediment grain size is about 0.01mm.The sediment in the east of Shicheng Island is mainly consisted of very coarse sand, and it is mainly from the coastal mountains and shoal erosion.The sediment in Xinghua Bay is mainly from river load, followed by peripheral coast erosion material and Cape Island sediment eroded by wind waves.Because of the stability of the flow path in flood tide or ebb tide and a strong driving force of tide current in the outer of the bay,the topography and tidal dynamics have a good correspondence and stability,and the sediment movement is restricted to the sediment transported inside the bay.关键词
