The Seman is a major river in western Albania. It is formed by the confluence of the rivers Devoll and Osum, a few km west of Kuçovë. It is 85km (53miles) long (281km (175miles) with its longest source river Devoll) and its drainage basin is 5649km2. Its average discharge is 95.7m3/s.[2] It meanders generally westwards through a flat lowland. Near Fier, the Seman receives the Gjanica from the left. It flows into the Adriatic Sea at the southern margin of the Divjakë-Karavasta National Park.
In classical antiquity, the Seman River was known as the Apsus, which is a derivative of the Indo-European root *ăp- "water, river". The Illyrian hydronym Apsus, corresponds to Apsias, a river name in southern Italy brought by Illyrian migrations (Iapygians) in the region.[3]
