Ebro

(ē`brō, ā`brō), Catalan Ebre,longest river entirely in Spain, c.575 mi (925 km) long, rising in the Cantabrian Mts., N Spain, and flowing SE between the Pyrenees and the Iberian Mts. past Logroño and Zaragoza. It empties through a wide delta into the Mediterranean below Tortosa. The river is of little use for inland navigation because of varying volume. In its middle course the waters are canalized for irrigation. The Jalón, the Gallego, and the Cínca-Segre are the main tributaries. Large hydroelectric power plants in the Ebro system supply c.50% of Spain's hydroelectricity.

Ebro

 

a river in northeastern Spain. The Ebro measures 928 km in length and drains an area of 86,800 sq km. It originates on the southern slopes of the Cantabrian Mountains and in a deep valley intersects the northeastern part of the Old Castile Plateau; in its middle course it intersects the Aragon Plain, where it divides in places into channels. In its lower course, along narrow, meandering gorges, it bursts through the spurs of the Catalonian Mountains, below which it reaches the maritime plain. It flows into the Mediterranean Sea, forming a delta (approximate area, 250 sq km), within which it flows in a straightened, embanked channel.

The water level increases in winter and spring, sometimes by as much as 4–6 m during floods. In summer and autumn the flow rate decreases, although flash floods occur. The mean flow rate in the lower course is 560 cu m per sec, with a maximum of 8,000 cu m per sec.

Within the Aragon Plain the Aragón and Tauste irrigation canals extend from the Ebro, watering more than 100,000 hectares (ha) of the Ebro valley. Hydroelectric power plants are found on the river. The Ebro is navigable below the city of Zaragoza. Other cities situated on the river include Miranda de Ebro, Logroño, and Tortosa.
