The fluvial network evolution of the middle watercourse of Guadalquivir river (Córdoba, Spain)

Abstract

An evolution model of the fluvial network of the Guadalquivir middle watercourse is proposed in three stages. A first phase would have a dentritic pattern and E-W predominant directions. In the lower pleistocene, derived from paleo-Guadalquivir river migration to the north, would have organized another model pattern similar to the current fluvial model with SE-NW predominant directions. Later, a new erosion phase during upper-middle pleistocene, would have generated the last fluvial captures and terrace deposits, 40 meters above the current alluvial plain of the Guadajoz and Galapagares rivers.
