%X We analyzed the relativity between the suspended sediment content (SSC) and the experimental hyperspectral data or Hyperion reflectivity. The sensitive band of experimental spectral reflectivity for SSC estimation in Sheyang Estuary water was centered around 898~904 nm, and for Hyperion image, the central wavelength of sensitive band was 896 nm. An exponential model was established with the reflectivity of band 896 nm, and the validation result of the model showed a good simulation precision with a relative root mean square error value of 38.78%. The time for water samples gathering was mostly accordant with that of Hyperion imaging, and therefore the SSC distribution rule in Sheyang Estuary was consistent with Hyperion interpretation: gradual reduction in the SSC from the shore to the open sea and a higher SSC observed in the southern shore than the north. The patterns were consistent with the actual conditions.
