The river runs through, firstly, a sector composed of tertiary sediments. This comprises the northern margin of the Central Catalan Depression to be introduced later in the Pyrenees mountains. Outside through the narrow and deep gorge (Gorge wall) on the basis of Alos de Balaguer, it then goes back to the depression of the Ebro. From Ebro, it then stretches to Camarasa-Balaguer.
