English: The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra and Aqua satellites acquired these images (below) on May 6 and April 20, during and before the flooding. Water overtopped the banks of the Jacuí, Cai, and Sinos rivers, inundating parts of Porto Alegre, the state’s capital city. Floodwater also spilled into several other cities, towns, and farmland upriver. Runoff, stained brown with suspended sediment, is visible flowing into the Patos Lagoon, south of Porto Alegre.
