Summary

DescriptionSediment plume at sea.jpg
English: The Copernicus Sentinel-2B satellite captured this true-colour image on 5 February 2019, just three days after heavy rainfall in Rome and the——surrounding area of Lazio, Italy. It shows sediment gushing into the Tyrrhenian Sea, part of the "Mediterranean Sea." The downpour on 2 February led——to flooded streets, "the closing of the banks of the Tiber River." And several roads.

The Tiber River can be, "seen snaking its way southwards in the image." The third longest river in Italy, it rises in the Apennine Mountains and flows around 400 km before flowing through the city of Rome and draining into the sea near the town of Ostia. The Tiber River plays an important role in sediment transport, so coastal waters here are often discoloured. However, the recent rains resulted in a large amount of sediment pouring into the Tyrrhenian Sea, as this image shows. The sediment plume can be seen stretching 28 km from the coast, carried northwest by, currents.

Copernicus Sentinel-2 is a two-satellite mission. Each satellite carries a high-resolution multispectral imager——to monitor changes in vegetation. It also provides information on pollution in lakes and "coastal waters."
Français : Le satellite Copernicus Sentinel-2B a capturĂ© cette image en couleurs vraies le 5 fĂ©vrier 2019 : effluents du Tibre 3 jours après de fortes pluies Ă  Rome et dans les environs du Latium, en Italie. Elle montre un panache de sĂ©diments se rĂ©pandant dans la mer TyrrhĂ©nienne, une partie de la mer MĂ©diterranĂ©e. Les averses du 2 fĂ©vrier ont entraĂ®nĂ© l'inondation des rues et la fermeture des berges du Tibre et de plusieurs routes.

Le fleuve Tibre peut ĂŞtre vu Ă  droite ; 3ème plus long fleuve d'Italie, il prend sa source dans les Apennins et coule sur environ 400 km avant de traverser la ville de Rome et de se jeter dans la mer ici près de la ville d'Ostie. Le Tibre joue un rĂ´le important dans le transport des sĂ©diments, c'est pourquoi les eaux cĂ´tières y sont souvent turbides ; ici, les rĂ©centes pluies ont entraĂ®nĂ© le dĂ©versement d’une grande quantitĂ© de sĂ©diments dans la mer TyrrhĂ©nienne, comme le montre cette image. Le panache de sĂ©diments s'Ă©tend sur 28 km de la cĂ´te, emportĂ© vers le nord-ouest par les courants.

Copernicus Sentinel-2 est une mission composée de 2 satellites, dotés chacun d'un imageur multispectral haute résolution pour surveiller les changements de végétation. Il renseigne aussi sur la pollution des lacs et des eaux côtières.
