In this study, semi-analytical algorithms such as two-band and three-band models were used to estimate the chlorophyll- a (Chl- a ) concentration in the turbid river using an airborne hyperspectral imagery. In order to select the optimal wavelength band to be used in the empirical equation, surface...
