中文摘要：
利用静止轨道水色遥感卫星GOCI的一天多景数据，采用基于半经验辐射传输模型（SERT），反演获得杭州湾海区悬浮泥沙浓度的时空分布；结合三维无结构三角形网格的有限体积海洋数值模型（FVCOM），模拟卫星成像时刻杭州湾水位、潮流分布状况。综合分析结果表明：潮流变化是该海区在涨落潮、大小潮悬沙分布变化的主要影响因素；风浪作用导致杭州湾海域悬沙浓度枯季明显大于洪季。
英文摘要：
A semi-empirical radiative transfer （SERT） model is employed to retrieve suspended sediment concen- tration （SSC） in the Hangzhou Bay using Geostationary Ocean Color Imager （GOCI） data that have 8 scenes in each day. A three-dimensional （3-D） unstructured-grid, free-surface, primitive equation, Finite-Volume Coastal Ocean Model （FVCOM） is applied to simulate tidal current distribution in the Hangzhou Bay at the moment of GO- CI overpass. Diurnal variation of the SSC distribution from FVCOM simulation are comprehensively analyzed. and fall during a tidal cycle. The flow changes Bay. The effects of wind-driven waves cause the from the GOCI observation and hydrodynamic environment The results show that the SSC has a change with tide rise should be the main impact factors on the SSC distribution in the SSC in winter larger than in summer.
