==Tributaries== thumb|right|300px|Map of Quang Tri province, showing Thach Han river. The Thạch Hãn river is formed by the confluence of two rivers which rise in the western highlands of Vietnam; the '''Đakrông''', which flows from the south-west through Đa Krông District, and the '''Rào Quán''', which rises in the mountains north of Khe Sanh.
In the plains the river is joined by three main left bank tributaries; the '''Ái Tử''', the '''Vĩnh Phước''', and the '''Hiếu''', known in its upper reaches as the '''Cam Lộ'''. The river enters the sea at Cửa Việt, east of Đông Hà city.
The Thạch Hãn is also connected by distributaries to the '''Bến Hải River''' to the north, marking what used to be the Demilitarized Zone, and the '''Ô Lâu''' to the south, which reaches the sea at the Tam Giang lagoon.
