After flowing through Palembang, the provincial capital, it joins with the several other rivers, including the Banyuasin River, to form a delta near the city of Sungsang. The river, dredged to a depth of about 6.5 meters, 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. This river system, especially around the city of Palembang, was the heart of eponymous 7th to 13th century Srivijayan empire.
