Hantaan

Hantaan River, also known as Hantan River or Hantan-gang, is a river on the Korean Peninsula. In Korean it is 한탄강. The river is part of the Imjin River watershed in the northwest of the peninsula.

Source and course: It originates in the Taebaek Mountain range, in the eastern part of the peninsula, and generally flows westward through parts of Gangwon and Gyeonggi Provinces. The river's lower reaches are near the border region with North Korea, and it eventually feeds into the Imjin River, which drains into the Yellow Sea.

Ecology and landscape: The Hantan River flows through a mix of forested hills, rural farmland, and small towns. The basin supports native fish and bird life and contains protected areas and scenic valleys that are popular for hiking and river recreation. Increased development in the basin has raised concerns about sedimentation, water quality, and habitat fragmentation.

Human use and management: The river provides water for irrigation and household use and hosts small-scale reservoirs and water-management facilities along its course. Because portions lie near the DMZ, access to some stretches is restricted, and conservation and transboundary water-management considerations influence local planning.
