Kaladan River

The Kaladan River is a river in eastern Mizoram State of India, and in Chin State and Rakhine State of western Myanmar. It forms the international border between India and Burma between 22° 47′ 10" N (where its tributary, the Tio River, joins it) and 22° 11′ 06" N.GeographyThe river arises in central Chin State as the Timit, 22° 49′ 28″ N 93° 31′ 57" E, and flows south and is soon joined by the Chal, after which it is known as the Boinu River. It continues south until just before it is joined by the Twe River at 22° 08′ 40″ N 93° 34′ 30″ E, when it swings west. It continues west until 22° 05′ 20″ N 93° 14′ 12″ E, when it heads northwest. At 22° 11′ 06″ N 93° 09′ 29″ E, below Mount Phabipa, it turns north and becomes the international border between India and Myanmar. It flows north to 22° 47′ 09″ N 93° 05′ 47″ E, where the international border continues north along the Tyao River, and the Boinu heads northwest into Mizoram State, at which point it is known as the Kaladan.At 22° 56′ 21″ N 92° 58′ 55″ E it reaches its northernmost point, and turns south west, is joined by the Tuichong River from the right and then heads south. The Kaladan is joined from the right by the Mat River at 22° 43′ 39″ N, 92° 54′ 46″ E. It continues south and is joined by the Kawrthingdeng River from the right. It again enters Chin State, at Raithaw Ferry, 22° 03′ 40″ N 92° 51′ 05″ E, just northwest of Khenkhar. The Mi River joins from the left at 21° 06′ 56″ N 92° 57′ 42″ E. At Ngame the river enters the Rakhine State of Myanmar and continues south to Sittwe where it enters the Bay of Bengal.
