The Ebro River on the northeast coast of Spain

Today’s Image of the Day from the European Space Agency features the delta of the Ebro River on the northeast coast of Spain, captured by the Copernicus Sentinel-2 mission.

Ebro River

“Stretching across 910 km of northern Spain, the Ebro River is the second-longest river in the Iberian Peninsula. In the image, it can be seen as a green line winding its way through the peninsula before flowing into the Mediterranean, shaping the Ebro Delta,” noted ESA.

“The Ebro River discharges more water into the sea than any other river in Spain. As suspended sediment flows from the river’s mouth, it tints the coastal waters with a turquoise hue.”

Ebro Delta

The Ebro Delta is one of the largest wetland areas in the western Mediterranean region. The river’s basin is the largest in Spain, covering about 85,000 square kilometers.

Historical significance 

Historically, the Ebro River has been significant in numerous battles, including the famous Battle of the Ebro during the Spanish Civil War, which was one of the war’s longest and deadliest conflicts. 

Economic significance 

Economically, the Ebro plays a crucial role in agriculture, particularly in regions like La Rioja and Navarre, which are known for their vineyards. Additionally, the river supports various industries and hydroelectric power generation.

Ecological significance

The Ebro Delta is ecologically rich, providing habitat for diverse bird species. It is also a vital area for rice cultivation in Spain. 

Nature reserve

“Most of the delta comprises the Ebro Delta Nature Reserve. With its protected wetlands, beaches, marshes, salt pans and estuaries, this reserve provides a natural habitat for numerous migratory birds and waterfowl,” said ESA.

Environmental challenges 

The river and its delta face environmental challenges such as pollution, water extraction for irrigation, and the impacts of climate change, which threaten its ecosystem and the sustainability of its water resources.

The northeast coast of Spain

The northeast coast of Spain is a vibrant and diverse region, characterized by its rich history, unique culture, and stunning landscapes.

It includes the autonomous communities of Catalonia, which features the dynamic city of Barcelona, and part of the Valencian Community. This area is also part of what is known as the Costa Brava, which stretches from the town of Blanes up to the French border.


The coastline is renowned for its rugged beauty, with rocky cliffs, secluded coves, and small beaches. The interior regions feature mountains such as the Pyrenees, which offer skiing in winter and hiking in the summer.

Cultural heritage

The area has a strong cultural identity, particularly in Catalonia, where there is a significant movement for independence. The Catalan language is widely spoken alongside Spanish. The region is also known for its festivals, architecture (notably the works of Antoni Gaudí in Barcelona), and traditional dances like the Sardana.


The cuisine is a delightful mix of fresh seafood from the Mediterranean, traditional Catalan dishes like “pa amb tomàquet” (bread with tomato), and rice dishes such as paella in the Valencian region. The area is also famous for its wines, including the sparkling wine Cava.


The northeast coast attracts millions of tourists each year due to its beautiful beaches, historical sites, and vibrant cities. Barcelona, in particular, is a major tourist destination with attractions like the Sagrada Familia, Park Güell, and the bustling La Rambla.


The economy of the northeast coast is one of the most dynamic in Spain, with Barcelona serving as a major hub for trade, education, entertainment, and technology.
