Musi River (Indonesia)

The Musi River (Indonesian: Sungai Musi) is a river in Southern Sumatra, Indonesia.^[8] It flows from south-west to north-east, from the Barisan Mountains range that form the backbone of Sumatra, in Kepahiang Regency, Bengkulu Province, to the Bangka Strait that forms an extension of the South China Sea. The Musi is about 750 kilometers long, and drains most of South Sumatra province. After flowing through Palembang, the provincial capital, it joins with several other rivers, including the Banyuasin River, to form a delta near the town of Sungsang. The river, dredged to a depth of about 8 meters,^[5] is navigable by large ships as far as Palembang, which is the site of major port facilities used primarily for the export of petroleum, rubber and palm oil.
