The gradient of the Okavango fan, Botswana, and its sedimentological and tectonic implications

Forecasting the spatial extent of the annual flood in the Okavango delta, Botswana

“…McCarthy et al (1997) detected a tectonic disturbance at the upper end of the Boro region as defined in Fig. 3, which has created a southwesterly orientated graben structure across the Boro channel, and has also induced local incision of the channel.…”

Desiccation of the Gomoti River: Biophysical process and indigenous resource management in Northern Botswana

“…Hydrologic and biotic processes in the Okavango operate at many scales from hippo movements, sedimentation of distributaries and development of mats of vegetation which close off madiba (sing. lediba) or oxbow lakes to processes affecting the entire delta system, chief among them mid-and long-term climate cycles and tectonics (McCarthy et al, 1997;Gumbricht and McCarthy, 2003, pp. 181-196).…”

Use of remotely sensed data in the analysis of soil‐vegetation changes along a drying gradient peripheral to the Okavango Delta, Botswana

“…The Etsha area exemplifies locations where the Delta margin has receded and exposed a series of flood plains in recent geological time about 2000-3000 years ago (Ringrose et al 2003b). The Shakawe area occurs peripheral to the Panhandle, where tectonic events have exposed a series of flood plains from the geological past estimated from regional multi-proxy data around 7000 years ago (McCarthy et al 1997, Partridge et al 1999, Ringrose et al 2003a). The Okavango Delta in total is underlain by medium fine sand and is characterized by a semi-arid climatic regime with an annual average rainfall in Maun of 460 mm.…”
