The
Ebro (
Catalan:
Ebre) is
Spain's most voluminous river. Its source is in
Fontibre (
Cantabria). It flows through cities such as
Miranda de Ebro,
Logroño,
Zaragoza,
Flix,
Tortosa, and
Amposta before discharging in a
delta on the
Mediterranean Sea in the province of
Tarragona.
Name
The
Romans named this river
Iber (Iberus Flumen), hence its current name but probably derives from the
greek Hèvros,
Εβρος. Arguably
the whole peninsula and
some of the peoples living there were named after the river.
History
In
Antiquity, The Ebro was used as the dividing line between
Roman (north) and
Carthaginian (south) expansions after the
First Punic War. When
Rome, fearful of
Hannibal's growing influence in the Iberian Peninsula, made the city of
Saguntum (considerably south of the Ebro) a protectorate of Rome, Hannibal viewed this treaty as an aggressive action by Rome and used the event as the catalyst to the
Second Punic War.
One of the earliest
Cistercian monasteries in Spain,
Real Monasterio de Nuestra Senora de Rueda (
Royal Monastery of Our Lady of the Wheel), is located on the banks of the Ebro in
Aragon. This edifice survives to the present intact, having been established in the year
1202. The monastery is strongly connected to the Ebro, since it used one of the first large
waterwheels established in Spain for the production of power. The monastery also diverted flow from the Ebro to create a circulating hydrological central heating system for its buildings.
The river Ebro was the initial starting ground of one of the most famous Republican offensives during the
Spanish Civil War, in 1938. The offensive itself, known as the
Battle of the Ebro, ended in defeat for the Republican forces, even though they enjoyed initial success in its first stages. However, they were not able to reach the desired objective of
Gandesa.
Delta geography
The Ebro
delta is one of the largest
wetland areas (320 km²) in the western Mediterranean region. The Ebro delta has grown rapidly—the historical rate of growth of the delta is demonstrated by the town of
Amposta. This town was a
seaport in the
4th Century, and is now located well inland from the current Ebro river mouth. The rounded form of the delta attests to the balance between
sediment deposition by the Ebro and removal of this material by wave
erosion.
The modern delta is in intensive
agricultural use for
rice,
fruit, and
vegetables. The Ebro delta also hosts numerous
beaches,
marshes, and
salt pans that provide habitat for over 300 species of birds. A large part of the delta was designated as
Ebro Delta Natural Park
in 1983. A network of canals and irrigation ditches constructed by both agricultural and conservation groups are helping to maintain the ecologic and economic resources of the Ebro Delta.

- February 2003: 2,988 m³/s
- March 2003: 2,220 m³/s
- April 2007: 2,282 m³/s.
The Ebro poured 1,874
hm³ in the
river delta from 2007-03-27 to 04-11, with an average of 117 hm³/day .
Ecology
The
zebra mussel is an
invasive species that's extending upstream in Ebro waters.
The Ebro delta has the world's largest colony of
Audouin's Gulls.
