		<abstract>Precise delimitation of water bodies is essential for several studies including watershed analysis. Its detection is able through techniques, such as spectral water indices, NDWI and MNDWI, and Fmask algorithm. Considering that individually those approaches are not accurate in different environments, we aimed in this work to evaluate the integration of Fmask to the NDWI and MNDWI for automatic detection of water bodies in Sentinel-2 images. The results indicate that the combination of these methods allow to reduce omission errors in an automatic process of water bodies detection.</abstract>
