AB Three main fluvial channels can be recognized in the Ebro delta plain with their respective depo-sitional lobes. The oldest one is the southern lobe and its channel, known as Riet Veil, was activein 1149 A.D. when the city of Tortosa was conquered by Ramon Berenguer IV, Count of Barcelona.Before 1362 A.D., probably as a consequence of the 1320 A.D. or 1324 A.D. floods, the river channel shifted to the north and the northern lobe started to grow. The northern lobe, with two or three active channels simultaneously, the Ampolla, Colero and Riet Fondo mouths, was active until themid or late XVII century. The central lobe has been growing since then for three successive mouths named Migjorn, Nord and Sorrapa. The influence of the climatic trend and the flood events is reflected in the avulsion frequency and in the river channel pattern, whereas the mouth morphology is strongly influenced by its orientation towards the sea.
