ABSTRACT A study of the avulsion of a major distributory channel on the alluvial fan (22 000
km2 in area) of the Okavango River in northern Botswana has revealed that channels serve …

Over the last six years, a multidisciplinary team from the University of Witwatersrand has
been carrying out research to establish the nature of the processes which underpin the …

The anastomosing system of the upper Narew River consists of a network of interconnected
channels. The channels are relatively deep (width/depth ratio 2–10), straight to sinuous, and …

This study investigated the distribution and determinants of marsh vegetation along the
major distributary channel system of southern Africa's largest wetland, the Okavango Delta …

Global change impacts on the Earth System are typically evaluated using biome
classifications based on trees and forests. However, during the Cenozoic, many terrestrial …

Channel instability has occurred in the Bell River in the form of meander cutoffs, a number of
which have occurred since 1952. Increased sediment loading from widespread gully erosion …

Abstract The Okavango Delta is southern Africa's largest wetland ecosystem and probably
the most pristine large wetland ecosystem in the world. Alex du Toit was the first to recognize …

A broad understanding of the structure and functioning of the Okavango Delta ecosystem
has provided a basis for evaluating the kinds of perturbations that are likely to affect the …

The relationships between vegetation, hydrology, and the landscape‐forming processes of
erosion and deposition are examined in channels of the northeastern Okavango Delta …

The response of vegetation to variable flood regimes is an important research question for
floodplains in semi-arid sub-Saharan Africa experiencing climate change. The Inland Niger …
