Drainage of the desert is by dry black valleys, seasonally inundated pans, and the large [[salt pan (geology)|salt pan]]s of the [[Makgadikgadi Pan]] in Botswana and [[Etosha Pan]] in Namibia. The only permanent river, the [[Okavango River|Okavango]], flows into a [[river delta|delta]] in the northwest, forming marshes that are rich in wildlife. Ancient dry riverbeds—called [[omuramba]]—traverse the central northern reaches of the Kalahari and provide standing pools of water during the rainy season.

A semi-desert, with huge tracts of excellent grazing after good rains, the Kalahari supports more animals and plants than a true desert, such as the [[Namib Desert]] to the west. There is little rainfall, and the summer temperature is very high. The driest areas usually receive {{cvt|110|-|200|mm}} of rain per year,<ref name="SAltena" /> and the wettest just a little over {{cvt|500|mm}}. The surrounding [[Kalahari Basin]] covers over {{cvt|2500000|km2}} extending farther into Botswana, Namibia, and South Africa, encroaching into parts of [[Angola]], [[Zambia]] and [[Zimbabwe]].
