Abstract

Water quality is an indispensable aspect in terms of its primary uses, especially for human supply purposes. This study aims to analyze some water quality parameters (turbidity, chlorophyll a, and Secchi's disk depth) in Doce River, using images from Landsat 8 satellite, made available through the Google Earth Engine platform. Data analysis was performed based on the water's characteristics before, during, and after Fundão Dam collapse, comparing remote sensing data provided by government agencies. The results obtained demonstrate the effectiveness of remote sensing as a tool for monitoring visible water quality parameters, highlighting significant changes in the disaster period, such as increased turbidity (about 445%) and loss of water transparency (approximately 29%) of Doce River.
