Genil

Genil River is the major tributary of the Guadalquivir River in Andalusia, Spain. The present name of the Roman Singilis comes from the Moorish rendition of the Roman name: Sinyil, Sannil, and Sinnil. The Genil originates in the Sierra Nevada, just north of Mulhacén, the highest peak in the range. Granada, Loja, Puente Genil, and Écija are all located along the Genil River. Near Palma del Ro, it empties into the Guadalquivir River. The Darro is its primary tributary. To the southwest of Villanueva Mesa, the Cacn River joins it.

The Granada basin is now drained by the river. This was an endorheic basin in the late Tortonian and the middle and late Turolian. Rivers flowed in from the east and southwest, but there was no way out of the middle lake. The paleo-Cacn river system, which flowed to the north and later departed the basin to the west during the Pliocene, drained the western section of the basin. The Alhambra system, or paleo-Genil system, drained the eastern half, which was fed by the mountains to the east and fed a tiny endorheic lake in the north. After a while, the Genil river shifted course and entered the paleo-Cacin system, causing the basin to become exorheic.
