Hydrology
The river originates in West Sumatra Province, in the Minangkabau Highlands, home of the Minangkabau people, and flows through Jambi Province to the east coast of Sumatra, reaching the sea in Nipah Panjang District of East Tanjung Jabung Regency. The Trans-Sumatran Highway (AH25) crosses the river at the city of Jambi which is located at some distance from the mouth of the river. The Batang Hari is used by the local population for fishing, transportation, mining, and personal hygiene.[6]
