             abstract = "Environmental indicators are important mechanisms to get 
                         information about the state of the environment, in particular 
                         water, which is a natural resource of great importance, whose 
                         quality it depend of human activities developed in the Watershed. 
                         Among the methods and techniques of image processing in order to 
                         hydrological analysis, we highlight the Normalized Difference 
                         Water Index (NDWI), a method has been instrumental in identifying 
                         and monitoring degraded areas and to support studies and proposals 
                         for environmental restoration. Therefore, this study adapted the 
                         NDWI so that it could reflect the availability of water for the 
                         present vegetation in the Una River Watershed, using in your 
                         calculation, scientific and technical bases of geoprocessing 
                         techniques. From the results, we found that the highest 
                         concentration of water stress in the vegetation is present in 
                         urban and agricultural areas, where vegetation have to compete 
                         with human activities for water availability. In general, the NDWI 
                         values were high, since all values are above 0.8, indicating that 
                         the study area does not suffer from water scarcity available for 
                         vegetation. This indicator allows numerically interpretation of 
                         water availability for vegetation in the Una River watershed, and 
                         thus a fast, simple and valid alternative for assessing the 
                         sustainability of the water, and can serve as a decision-making 
                         tool for public managers and stakeholders on this issue.",
