The New Student's Reference Work/Guadalquivir

Guadalquivir (ga̤′dȧl-kwĭv′ẽr), meaning the great river, the largest river of Spain and the only one that all the year round has a full stream. It rises in the Sierra de Cazorla, flows 374 miles in a southwesterly direction, and empties into the Gulf of Cadiz. It is a slow, sluggish stream, only breaking into rapids near the Sierra Morena. It is navigable as far as Seville, 80 miles from its mouth.
