                         best comprehension of structures ecosystems and your interaction 
                         with the electromagnetic radiation. But, there are methodological 
                         difficulties for the processing of high resolution hyperspectral

                         radiometric data of detected reflectance by the sensors in field 
                         (in situ), directly influencing in choose of technique for use in 
                         mathematical modeling, it is difficult the analysis using only 
                         originals spectra. In this sense the technique of derivative 
                         analysis of the hyperspectral data, calculation attribute, was 
                         used with a goal of study the variation of optically active 
                         components (COAs) in water, through of data from field. The 
                         studied environment was the low course of river Suba{\'e}, Santo 
                         Amaro city, state of Bahia. The procedures of mathematical 
                         modeling adopted was the derivation by finite approximation of 
                         values of reflectance of filtrated originals spectra and first 
                         derived (for the second order) related the a finite band of 
                         wavelength. It was observed a relation between the behavior of 
                         spectrorradiometric originals curves, the obtained curves from the 
                         spectra derivate technique and chlorophyll-a concentrations. The 
                         first order derivative presented satisfactory results for features 
                         of chlorophyll-a. However the obtained graphics with application 
                         of second derivative, presented strong irregularity of values 
                         derived, its related to other COAs which were not included in the 
                         modeling. From the methodological procedure was possible to 
                         demonstrate the potential of successive derivation, corroborating 
                         with other authors.",
