Of Seville; Alcala del Jucar (2968), on the Jucar, in Albacete; Alcala de la Selva (1490), on the southern slopes of the Sierra del Gudar, in Teruel; Alcala de la Vega (712), on the river Cabriel, in Cuenca; Alcala de Gurrea (632), on the river Seton, in Huesca; Alcala del Obispo (432), in the same province; Alcala de Ebro (388) and Alcala de Moncayo (367), both in Saragossa.
From Miranda to Mora the Bilbao-Tarragona railway follows the course of the Ebro along the right bank.
Under the Moors it was of great importance as the key of the Ebro valley.
The Alphonsist armies, led by Marshals Campos and Jovellar, swept the Carlist bands from the right hank of the Ebro to the Pyrenees, and took their last strongholds in the eastern provinces, Cantavieja and Seo de Urgel.
The exports are chiefly iron; the imports coal; large quantities of wine from Navarre and the Ebro valley are also sent abroad, and the importation of timber of all kinds from Scandinavia and Finland, and coastwise from Asturias, is of great importance.
In its length, approximately 465 m., the Ebro is inferior to the Tagus, Guadiana and Douro; it drains an area of nearly 32,000 sq.
The principal rivers entering the Mediterranean directly are the Nile from Africa, and the Po, Rhone and Ebro from Europe.
Andalusia consists of a great plain, the valley of the Guadalquivir, shut in by mountain ranges on every side except the S.W., where it descends to the Atlantic. This lowland, which is known as Andalucia Baja, or Lower Andalusia, resembles the valley of the Ebro in its slight elevation above sea-level (300-400 ft.), and in the number of brackish lakes or fens, and waste lands (despoblados) impregnated with salt, which seem to indicate that the whole surface was covered by the sea at no distant geological date.
The Ebro rises at Fuentibre, a hamlet among the Cantabrian Mountains, in the province of Santander; at Reinosa, 4 m.
The Llanos de Urgel, which comprise the greater part of southern Lerida, are extensive plains forming part of the Ebro valley, but redeemed by an elaborate system of canals from the sterility which characterizes so much of that region in Aragon.
