Response Relation between Sediment Particle-size Distribution and Hydrodynamic Characteristics in Offshore Area of Jiangsu Province

摘要

The whole coastline of Jiangsu province is 954km. It starts north fromrnXiuzhen estuary, which is the junction of Jiangsu and Shandongrnprovince, and south to the north bank of the Yangtze River estuary.rnAccording to composition, it can be divided into three categories,rnincluding sandy coast, rocky coast and muddy coast. Due to differencesrnof hydrodynamic characteristics, the coast of Jiangsu is separated intornfour regions. There laid 24 typical spots in Jiangsu offshorerninvestigation and assessment (JS908), to collect bed load particle size,rnsuspended sediment particle size, suspended sediment concentration,rnflow rate, water temperature, salinity and others. Based on particle-sizernanalysis of a number of sediment samples, combing sediment source,rntidal wave, tidal current, storm current and etc, the relationship isrnconcluded between particle-size distribution and hydrodynamicrncharacteristics.
