             abstract = "The aquatic macrophytes are among the primary producers in 
                         artificial reservoirs and can be classified into four groups: 
                         rooted, floating, emergent and submerged. The radiation 
                         availability is the main limiting factor in the growth of 
                         submerged macrophytes (or submerged aquatic vegetation - SAV). The 
                         Secchi depth (SD) is a fundamental variable in limnological 
                         studies, and it is an indicator of water transparency. The water 
                         transparency is directly related to radiation availability; hence 
                         the SD is useful in SAV studies. Therefore, the goals of this 
                         study were to estimate the SD using SPOT-6 image and evaluate the 
                         development of SAV based on the SD estimated by remote sensing. 
                         The study area was a section of the Nova Avanhandava Reservoir, 
                         which belongs to the reservoirs cascade of the Tiet{\^e} River - 
                         S{\~a}o Paulo, Brazil. The regression between the centered band 
                         at 660 nm and the SD resulted in a Rē = 0.73 and a NRMSE = 21.5%. 
                         The SD map was made using the atmospherically corrected SPOT-6 
                         image and the calibrated SD prediction model. Two regions with 
                         different SD (Class 0.0 - 1.0 m and Class > 5.0 m) were selected 
                         to evaluate the SAV height. Therefore, it was observed that under 
                         different SD conditions there is a change in both maximum height 
                         reached by the SAV and the depth of its occurrence.",
