SPAIN’S WATERSHEDS

WATERSHEDS

Spain has 3 watersheds:o Cantabrian watershedo Atlantic watershedo Mediterranean

watershed

A watershed is an area of land that water flows over on its way to the sea.

Atlantic Watershed

Cantabrian Watershed

Mediterranean Watershed

CANTABRIAN WATERSHED

Their flow is regular and high due to abundant rainfall.

The rivers that flow into the Bay of Biscay are short as they start in the mountains near the coast.

ATLANTIC WATERSHED• The rivers are long and carry high volumes of

water that flow into the Atlantic Ocean.

Rivers that flow into the Atlantic Ocean can be divided into:

•Short with high flow due to abundant rainfall.

Galician Rivers

•Long with high but irregular flow.

Rivers that cross the Meseta

•Usually long with very low flow.

Andalusian Rivers

MEDITERRANEAN WATERSHED• Most of the rivers that carry water to the

Mediterranean Sea are short and have limited and irregluar water flow, except the Ebro.

TAMBRE RIVER

ULLA RIVER

Xallas River is a rare example in Europe: it dies as a waterfall when it flows into the sea.

Unfortunally, an energy company keeps the river to itself and there is almost no water in the fall. The company delights us "opening" the waterfall 2 or 3 hours on weekends and during the summer.

XALLAS RIVER

RIVERS THAT

CROSS THE MESETA

ARRIBES DEL DUERO

The Duoro river has the most abundant flow in Spain.

ALEADÁVILA DAM, SALAMANCA

(Middle course of Duoro River)

TAGUS RIVER The longest river in Spain.

TAGUS RIVER IN MONFRAGÜE NATIONAL PARK

Its course has been altered by human activity: construction of reservoirs and Tagus-Segura water-diversion system.

Its flow increases in Portugal due to rainfall.

Due to the lack of water in the Southwest the Tajo-Segura water-diversion system was constructed. This affected the Tajo, Guadiana, Júcar and Segura Basins.

WETLANDS

There are about 637 inland freshwater wetlands

Spain is home to almost all of Europe's saline steppe wetlands.

Groundwater extraction for irrigated agriculture has almost led to the loss of the internationally important wetland of the Tablas de Damiel

marshes.

Doñana (Huelva) is one of the largest and most important remaining wetlands in Europe.

In April 1998 there was an accidental spillage of toxic mining waste, which contaminated a large area of these wetlands.
