Kura (South Caucasus river) in the context of "Liakhvi River"

The Aras is a transboundary river in the Caucasus. It rises in eastern Turkey and flows along the borders between Turkey and Armenia, between Turkey and the Nakhchivan exclave of Azerbaijan, between Iran and both Azerbaijan and Armenia, and, finally, through Azerbaijan where it flows into the Kura river as a right tributary. It drains the south side of the Lesser Caucasus Mountains, while the Kura drains the north side of the Lesser Caucasus. The river's total length is 1,072 km (666 mi) and its watershed covers an area of 102,000 km (39,000 sq mi). The Aras is one of the longest rivers in the Caucasus.

The Kura-Aras Lowland, Kura-Aras Depression or Kura-Aras Basin (Azerbaijani: Kür-Araz ovalığı) is a vast depression in central-southern Azerbaijan defined by the valleys of the Kura River and Aras River. It is situated by the West shore of the Caspian Sea and is part of the Aral-Caspian Depression. It is delimited by the Greater Caucasus from the North, Lesser Caucasus from the West and the Talysh Mountains from the South. The name is derived from the names of the two rivers in the area: the Kura and the Aras.

The Hrazdan (Armenian: Հրազդան, Hrazdan) is a major river and the second largest in Armenia. It originates at the northwest extremity of Lake Sevan and flows south through the Kotayk Province and Armenia's capital, Yerevan; the lake in turn is fed by several streams. In the Ararat plain it joins the Aras river along the border with Turkey. It joins as a left tributary the Kura river, which then flows into the Caspian Sea.

A series of hydro-electric projects have been constructed on the Hrazdan. Its waters are in demand to irrigate crops.
