Modern river Guadalquivir. Its ancient course was the same as today, but originally, its delta had four branches (Avien. 288ff.), and two in the Augustan period (Str. 3,1,9; 2,11); nowadays, it discharges into the Atlantic from a single course; the silted branches of the delta can still be detected. Its high water levels seem to have remained unchanged: large seagoing vessels sailed upriver to Hispalis, small ones to Ilipa, and river barges to Corduba (Str. 3,2,3).
