Dori River: A Transboundary Waterway of Afghanistan and Pakistan
The Dori River is a significant transboundary waterway that traverses the rugged landscapes of Pakistan and Afghanistan. Spanning a total length of 320 kilometres (200 mi), this river serves as a vital geographic feature connecting the Balochistan province of Pakistan with the Kandahar Province of Afghanistan, eventually contributing its flow to the Arghandab River.

Course and Nomenclature
The river's identity changes as it crosses borders and terrains, known by three different names depending on the region. It originates north of Quetta, the provincial capital of Balochistan in Pakistan. In these headwaters, the river is known as the Lora.
As the waterway crosses the border into Afghanistan, its name shifts to the Kadanai. Once it flows past the town of Spin Baldak, it is officially referred to as the Dori.

Geography and Tributaries
Upon entering Afghanistan, the Dori initially flows westward. Its path soon brings it into contact with the Rigestan, a vast sandy desert located in the southeastern region of the country.
After encountering the desert, the river pivots to a northerly direction. It passes to the east and northeast of Takht-e Pol, marking the southeastern border of the Kandahar Valley. As it continues its journey, the Dori is joined by two significant tributaries:
- The Arghistan River.
- The Tarnak River, which joins the Dori approximately 30 kilometres (19 mi) south of Kandahar city.
The river's journey concludes as it merges into the Arghandab River, forming part of the broader regional drainage system.
