The Avrig River is a left tributary of the river Olt in Romania. It discharges into the Olt in the town Avrig. The upper reach of the river is also known as Râul Mare. It starts at the confluence of the headwaters Avrigel and Auriștea.
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.
The Olt is a river in Romania. It is 615 km (382 mi) long, and its basin area is 24,050 km2 (9,290 sq mi). It is the longest river flowing exclusively through Romania. Its source is in the Hășmaș Mountains of the eastern Carpathian Mountains, near Bălan, rising close to the headwaters of the Mureș River. It flows through the Romanian counties Harghita, Covasna, Brașov, Sibiu, Vâlcea and Olt. The river was known as Alutus or Aluta in Roman antiquity. Olt County and the historical province of Oltenia are named after the river.
