Abstract
The sustainable water management fundamentally depends of the water quality information and how this quality surfer alteration along the time as a response to different factors. In specific case of reservoirs the lentic regime is an additional aggravating, because can conduct the aquatic system to a eutrophication and salinization processes. Generally in water quality studies are based in a limited samples that underestimating the spatial variability of water properties. This underestimation becomes more critical in case of large reservoirs. The remote sensing can be a powerful tool in aquatic system studies by capturing the spectral response of the actively optical components present in the water synoptically. In Brazil is a challenge to use physically based models, that is independents of the site that was developed, to study the water optical properties. This, the objective of this research is to develop a semi-analytical model to be applied to the hydroelectric reservoirs decreasing the costs and also subsidizing the water quality management efficiently.
