Abstract

The channel dynamics of an ephemeral sandbed river, the Metsemotlhaba in southeast Botswana, were studied over a 5 year period using tagged magnetic particles of pebble and cobble size, scour chains and topographic cross-sections, with particular emphasis on the three-dimensional dispersal of gravels, patterns of scour and fill and depth of active layer. Two major flow events of equivalent magnitude occurred, moving the tagged particles in December 1987 and in March 1991. Discussion of the results : longitudinal transport, burial depth distribution
