the spectral response of turbid waters caused by different clay materials (bentonite clay, black cotton soil, kaoline, and grey soil) was studied using a spectro-radiometer in the 450 to 1000 nm wavelength. illumination was provided by a 1000 w lamp. the analysis shows a linear relationship between turbidity and percentage reflectance for bentonite clay and black cotton soil, whereas curvilinear variation was observed for kaoline and grey soil. the organic content of all the clay materials was determined and, in the 550 to 750 nm wavelength, grey soil which has the lowest organic content shows the highest reflectance whereas black cotton soil with the highest organic content shows lowest reflectance.
