The hydro-sediments characterization and the erosive processes of the rivers Cesar and Guatapurí, medium course

Abstract

The Cesar River originates in the South East edge of the Sierra Nevada of Santa Marta, and crosses the departament of the Cesar, the Guatapurí River is also born in the Sierra Nevada of Santa Marta, it ends in the right bank of the Cesar River, down watters Valledupar City. Geologically both are framed by the Sierra Nevada of Santa Marta's igneous-metamorphic complex. The Cesar and Guatapurí Rivers present different and contrasting hydro-sedimentologic characters. The Cesar River shows a high sinuosity, a presence of sedimentation bars, the gradient are gentle; a high relatonship of suspenden silts/load channel, high rate of lateral migration, and intense erosive phenomena and deposit on bars of silits. We can classify as braided, and from the point of view of the development state, it con be considered as a young system characteristic of mountainous regions.
