The 391-km long river has its source in the Main Caucasus Mountain Range (elevation 2,600-2,800 m a.s.l.). The Alazani/Ganyh flows for a substantial part of its length along the Gcorgia-Azcrbaijan border, and discharges into the Mingachcvir Reservoir in Azerbaijan. There is currently some concern about worsening conditions for generating baseflow.
