2.1 Water as a function of inorganic:
Minerals such as silicon, aluminum, and iron oxides are found in suspension in most
natural water bodies. The particles range from fine clay particles (< 0.002mm in
diameter), to silt (0.05 - 0.002 mm), and sand ( 2-0.05 mm).
The peak reflectance shifts toward longer wavelengths in the visible region as more
suspended sediments are added.
the visible wavelength range of 580-690 may provide information on the type of
suspended sediment (soil) in surface water
