The elevation map of South Sudan is characterized by the presence of lowlands, plateaus, and highlands. The country has a uniform slope from south to north, with the southern part being low-lying and the north having higher elevations.
The country is dominated by the waters of the Nile River and its tributaries, which occupy most of the land. The Nile Valley and its floodplains are found along the river's course and cover the largest portion of the country's landmass.
South Sudan's highest elevations are found in the Imatong Mountains, situated in the southeastern part of the country. The terrain in this region is rugged and hilly, with a peak elevation of Mount Kinyeti at 3187 meters above sea level.
The low-lying areas in the country are mainly characterized by savannah grasslands, which are interspersed with swamps, marshlands, and riverine forests. The White Nile is responsible for the largest swamps in the world, the Sudd, which occupy a considerable portion of South Sudan's land area.
The highest point in South Sudan is Mount Kinyeti, located in the Imatong Mountains in the southeastern part of the country. The peak stands at 3187 meters above sea level, making it the country's highest elevation point.
The lowest point in South Sudan is the confluence of the White Nile and Sobat Rivers, with an elevation of approximately 380 meters above sea level.
South Sudan shares its borders with countries such as Sudan, Kenya, Uganda, Ethiopia, and the Central African Republic. Some of these countries have similar topographic features, such as Uganda and Ethiopia, which have highlands, lowlands, and plateau regions.
