Spain is home to several major rivers that play a crucial role in its geography and economy. The longest river is the Ebro, which flows through northeastern Spain and empties into the Mediterranean Sea. Other significant rivers include the Tagus, which runs through central Spain and is the longest river on the Iberian Peninsula, and the Guadalquivir, known for its historical importance and connection to cities like Seville. These rivers support agriculture, provide water for cities, and offer recreational opportunities. The Duero is another important river, flowing through northern Spain and into Portugal, while the Júcar and Genil are smaller rivers that also contribute to the region's water system.
