Optimum band to predict soil content in water

The paper quantitatively analyzed the relationship between suspension sediment (soil) content and water spectral reflectance with the data tested with FieldSpec FR spectrometer. Then discussed the factors influencing water reflectance. After comparing the results from regressing analysis of reflectance and contents of soil at each wavelength from 350nm to 2500nm, the optimum band (wavelength) was found. The results were proved by another group of data. The conclusion would be helpful in estimating soil content of sea, river or flood with hyperspectral remote sensing, and evaluating soil erosion within water system.
