evidence: Drainage [edit]Several river systems drain the South Region. The northernmost of these is the Nyong, which forms part of the border with the Littoral. The coastal Ocean division is drained by two rivers, the Lokounje to the north and the Lobé to the south. The Ntem, or Campo, rises in the east of the region and flows along or just north of the southern border to the town of Campo. All of these rivers empty into the Atlantic Ocean. [...] Relief [edit]The South Region begins at sea level on the coast. The land slowly climbs throughout the Kribi-Douala basin, which averages 300–600 metres in altitude, until it reaches the South Cameroon Plateau with elevations of 500 to 1000 metres above sea level. Rocky promontories on the coast and rolling, tree-covered hills inland characterize the land. The Ntem Massif near Ebolowa is the province's highest point at 1400 metres. [...] The Océan department is the farthest west, located on the coast and administered from Kribi. Bordering this are the Vallée-du-Ntem (Ntem-Valley) department, governed from Ambam, and the Mvila department, headed from Ebolowa. Farthest east is the Dja-et-Lobo (Dja and Lobo) department, with Sangmélima its capital.
