Abstract
A laboratory experiment was designed to collect the spectral reflectance of water containing suspended particulate matter (SPM) in terms of its concentration. By performing surface-fitting analysis, an empirical relationship among the wavelength, reflectance, and concentration of SPM in water was obtained. The results showed that a linear effect of the spectral wavelength on spectral reflectance with increasing concentration of SPM in water, and the relationship between the reflectance and concentration of SPM in water is quadratic. Hyperspectral remote sensing is expected to play an important role in estimating the concentration of SPM in water.
