Argentina and Uruguay – June 25th, 2012

The Uruguay and Paraná Rivers and the sediments they carry join together in the upper left quadrant of this image to form the extremely silty Río de la Plata river and estuary on the border between Argentina and Uruguay. As the sediments flow through the 290 kilometre (180 mi) long funnel-shaped indentation of the estuary, they gradually diffuse into deeper waters approaching the Atlantic Ocean and become lighter in color. Visible on the shores of the estuary are Buenos Aires, the capital of Argentina (left), and Montevideo, the capital of Uruguay (right).

December 10th, 2010 Category: Image of the day, Rivers

Argentina and Uruguay - December 6th, 2010

The Rio de la Plata estuary appears tan with sediments from the Uruguay and Paraná Rivers. The Uruguay River flows southward from the top center of the image, while the Paraná flows southward from the top left, then curves to the east before its confluence with the Uruguay.

Where the two rivers meet, they form the Rio de la Plata, which passes by the Argentine capital of Buenos Aires (visible as a grey area on the lower banks) and the Uruguayan capital of Montevideo (visible as a grey area on the upper banks, further east). The latter is best observed in the full image.

Many reservoirs can be seen near the  Paraná River in Brazil, the second longest river in South America after the Amazon. The river appears greenish in color, flowing diagonally through the lower left quadrant.

Many reservoirs can be observed nearby, most of which are situated on the borders between Brazilian states: Goiás (above), Minas Gerais (upper right),São Paulo (lower half of image), and Mato Grosso do Sul (center left).

The lake situated at the image center is the José Ermirio de Moraes Reservoir, also known as the Água Vermelha (Red Water) Reservoir. It is located along the Grande River, at 80 km from its confluence with the Paranaíba River. It is 3940 meters long and 67 meters high, with a surface area of 647 km².

Brazil - January 26th, 2010

Brazil - January 26th, 2010

This FAPAR image shows the vegetation index of South America around the Paraná River. Parts of southern Brazil, including the states of Mato Grosso do Sul (west of the river), São Paulo (east of the river, above) and Paraná (east of the river, middle) are visible, as well as some areas of Paraguay and Argentina near the triple border by the Iguazú falls.

The majority of the image shows a good to high vegetation index: green areas are indicative of good photosynthetic activity, and red areas are indicative of high activity. Yellow areas, of which there are few, indicate low activity.
