Salween River much of its length, the Salween's course is nearly parallel to that of the much larger Mekong in the east. Although the commonly accepted name is Salween, the river is known by a handful of other names regionally: "Nu" in China, "Thanlwin" in southern Burma, and "Salawin" on the border of Thailand and Burma. Several major sub-continental drainage basins border on the Salween. The Mekong basin forms nearly the entire eastern boundary of the watershed, while the Irrawaddy River flows southwards on the west side of the basin. The smallest boundary is formed by the Yangtze to the extreme north.
Little Brosna River Little Brosna River The Little Brosna River ("An Bhrosnach Bheag" in Irish) rises near Dunkerrin, County Offaly, Ireland. It flows for 36 miles before joining the River Shannon. The river rises near Dunkerrin, and enters the River Shannon near Victoria Lock, Clonahenoge. It flows over an area of limestone then passes through an area of Callow before merging with the Shannon. It forms part of the boundary between County Offaly and County Tipperary. Sharavogue Bridge built in the early 1850s carries the R492 road over the river which here forms the boundary between the townlands of Sharavogue and Ballincor Demesne.
