This research explored the potential of the use of the CCD image of the HJ satellite to derive Suspended Sediment Concentrations （ SSC） of dynamic water bodies at Hangzhou Bay

which is a typical turbid water body in China. Through the analysis on the correlation between Remote Sensing Reflectance （ Rrs ） and SSC

two apparent reflectance peaks at approximately 690 and 830 nm have been found in the third and fourth bands

respectively. The result also shows that a good correlation exists between R rs and SSC when the wavelength is more than 700 nm. Based on the measured correlation between SSC and Rrs

the retrieval model is established using the ratio of band 4 and band 3 as remote sensing factor

and the model determination coefficient of 0. 90 is reached. Through the Moderate Resolution Imaging Spectroradiometer （ MODIS）-derived Aerosol Optical Depth （ AOD） data

which are calculated from the Near Infrared-Short Wave Infrared （ NIR-SWIR） atmospheric correction

the atmospheric correction of HJ CCD imagery is realized. The correction-relative errors of the third and fourth bands are 5. 54% and 6. 97%

respectively. The result demonstrates that the relative error of SSC derived from HJ CCD imagery is 7. 12%

and SSC at Hangzhou Bay

which also has significant internal diversity

is much higher than that in the entrance of the Yangtze River. This research demonstrated that HJ CCD imagery can be used to evaluate SSC at Hangzhou Bay

if the appropriate atmospheric correction method and retrieval a lgorithm are used.
