Spain - January 8th, 2010

While much of the rest of Europe has been experiencing an Arctic chill with snowfall, southern Spain and Portugal appear free of the white, powdery substance. The Guadalquivir River, on the other hand, can be seen emptying a thick load of tan sediments off the coast of Spain, probably due to heavier precipitation further north.

The Guadalquivir is the second longest river in Spain (fifth after the Tagus, Ebro, Duero and Guadiana), and the longest in Andalusia. The Guadalquivir is 657 kilometers long and drains an area of about 58,000 square kilometers. It begins at Cañada de las Fuentes in the Cazorla mountain range (Jaén), passes through Córdoba and Seville and ends at the fishing village of Bonanza, in Sanlúcar de Barrameda, flowing into the Gulf of Cádiz, in the Atlantic Ocean. The marshy lowlands at the river’s end are known as “Las Marismas”. It borders Doñana National Park reserve.

The Spanish land along the Gulf of Cádiz sports a varid terrain. Of particular interest is the tan, sandy area along the coast, which is part of the Doñana National Park  and wildlife refuge.

Doñana National Park is located in Andalusia, in the provinces of Huelva and Seville, and covers 543 km², of which 135 km² are a protected area. The park is an area of marsh, shallow streams, and sand dunes in Las Marismas, the Guadalquivir River Delta region where it flows into the Atlantic Ocean.

The original area was established in 1963 when the World Wildlife Fund joined with the Spanish government and purchased a section of marshes to protect it from the constant threat of draining the marshes, using the river water to boost agricultural production by irrigating land along the coast, and expanding tourist facilities.

Such drained marshes and agricultural lands are visible above the park, around the  tan  line of the Guadalquivir River. The light green areas are used for agriculture, while the bright green and greyish tan patches are salt flats from which salt is extracted for commercial purposes.
