tribe), Kosalu River, Isundiga River, and Girande River, among others. The Westobou River was the former name of the Savannah River that was derived from the

(also known as Westoe) Native Americans. The Westo were thought to have migrated from the northeast, pushed out by the more powerful tribes of the Iroquois Confederacy, who had acquired firearms through trade. This migration, beginning in the late 16th century, resulted in the Westo Indians reaching the present area of

tribe, who defeated the Westo in the Westo War of 1680. Following this, the English colonists renamed the river as the Savannah; it was integral to early development. They founded two major cities on the river during the colonial era: Savannah was established in 1733 as a

Land cover and land use history

The Savannah River basin in the Southeast region of the U.S. has been experiencing environmental change from anthropocentric activities. The conversion of the vegetation cover, including the urban growth, agriculture expansion, and deforestation and reforestation take place throughout the basin, especially near the lakes and tributary waters in the middle and lower Savannah Basin. The continuous change of land use such as the conversion of forest areas to other types of land cover and vice versa can significantly lead to increasing threats to the environmental systems of the region.
