Tuul

The Tuul is a river in northern Mongolia, a tributary of the Selenge River. It flows generally westward across the country and ultimately contributes to the Selenga watershed that drains into Lake Baikal. The river passes near the capital city, Ulaanbaatar, and its valley is a notable geographic feature of the region.

The name Tuul derives from the Mongolian word for wind, reflecting a common linguistic connection to natural features in the area.

Origin and course: The Tuul originates in the Khentii Mountains in eastern Mongolia. From there it runs westward through the northern landscapes of several aimags, before joining the Selenge River in northern Mongolia. Along its route the river traverses both rural and more densely populated areas.

Usage and environmental context: The Tuul is used for water supply and livestock needs in communities along its banks. It also supports recreational activities and serves as a scenic and ecological corridor near urban areas. Ongoing development, urban expansion around Ulaanbaatar, and upstream activities pose hydrological and water-quality challenges that are monitored and managed by regional authorities and conservation groups.

Ecology and conservation: The river supports a range of freshwater habitats and migratory birds, with biodiversity concentrated along its varied landscapes. Conservation efforts focus on maintaining water quality, protecting riparian ecosystems, and balancing the needs of local communities, industry, and tourism along the Tuul’s course.
