Efficient water bodies management techniques require an accurate characterization of water availability on reservoirs and dams. Some studies using Earth Observation (EO) and Spatial Analysis of data, namely Vilar et al. (2015) and Patriarca et al. (2021), have been studying and automating methodologies using multispectral satellite images to manage water resources in environmental context and agricultural water management. Based on geospatial information extracted from EO data using multispectral Sentinel-2 (S2) mission, this study shown the efficiency to inventory and characterize water bodies on ARTHO region, centre of Portugal, early demonstrated by Patriarca et al. (2021). The methodology presented here was implemented on ESRI ARCGIS® software. The main objective of this methodology was to assure operational capabilities for water bodies management, comprising two steps: phase I water bodies inventorying by using S2 images; phase II – water bodies volume (WBV) estimating using spatial analysis techniques.
