The Kaidu River (Chinese: 开都河; pinyin: Kāidū Hé; Mongolian: Хайду гол; Uyghur: قايدۇ دەرياسى), also known under its ancient name Chaidu-gol, is a river in the Xinjiang Uyghur Autonomous Region of China and an important source of water for the region.

[5] Northwest China has been subjected to affects from the Kaidu River because of global warming and water perturbation.

Additionally, the Kaidu River resides in an arid zone, causing many different trends in temperature due to this climate change.

[6] Land use-conversion is also a very problematic issue that is caused in the region of Northwest China due to climate change as well.

This led to an increase in water management activities, which became an issue because of the consistent change of runoff.
