Botswana

The country is a broad tableland with a mean altitude of 3,300 ft. A vast plateau of about 4,000 ft in height, extending from near Kanye north to the Zimbabwean border, divides the country into two distinct topographical regions.

The eastern region is hilly bush country and grassland (veld). To the west lie the Okavango Swamps and the Kalahari Desert. The only sources of permanent surface water are the Chobe River in the north, the Limpopo in the east, and the Okvango in the northwest. In seasons of heavy rainfall, floodwaters flow into the Makarikari Salt Pans and Lake Ngami.
