Groundwater recharge in the Kalahari, with reference to paleo-hydrologic conditions.
TL;DR: In this paper, the results of an extensive recharge research project at the eastern fringe of the Kalahari, which is the most favorable part for groundwater replenishment, were reported.
Journal ArticleDOI
Regional review: the hydrology of the Okavango Delta, Botswana—processes, data and modelling
TL;DR: The history of hydrologic models of the Okavango Delta is retraced from the early box models to state-of-the-art distributed hydrological models as discussed by the authors.
Journal ArticleDOI
Groundwater evolution, chemical sedimentation and carbonate brine formation on an island in the Okavango Delta swamp, Botswana
TL;DR: In this article, the relation between soil chemistry and mineralogy, and swamp and groundwater chemistry were investigated on an island in the Okavango Delta in Botswana, and it was shown that the water table beneath the island is depressed and swamp water enters the groundwater regime of the island from the margins and below, and flows toward the centre.

Susanne Stadler,Susanne Stadler,Karsten Osenbrück,Kay Knöller,Axel Suckow,Axel Suckow,Jürgen Sültenfuß,H. Oster,Thomas Himmelsbach,Heinz Hötzl +9 more
TL;DR: In this article, a multidisciplinary approach (hydrogeology, isotope hydrology, and geochemistry) was applied to understand the origin and fate of nitrate in groundwater of the semi-arid Kalahari of Botswana.

Radiocarbon and tritium evidence for direct rain recharge to ground waters in the northern Kalahari
TL;DR: The Kalahari region has been classified as a desert region because of the virtual absence of surface waters in the form of springs or perennial rivers as discussed by the authors, and the only exception is the inland drainage system in the north, the Okavango delta and Makgadigadi salt pan, which are fed successively by rainwater which drains from the remote highlands of Angola through the Okava river.
