The impact of land-use and climate change on water and sediment yields in Batanghari Watershed, Sumatra, Indonesia

The Batanghari River flows from the province of West Sumatra into the West Coast of Jambi, with the main river extending up to 870 km. Also, the Batanghari watershed Land use changes have shown a decreasing forest cover and an increasing agricultural area. Therefore, this study aims to calculate the...
