Description :
Concentrating on processes rather than steady-state descriptions, this paper attempts to explain the profound spatial and temporal variations of uranium pollution observed in the Wonderfonteinspruit (WES) catchment, located on the interior plateau of South Africa. The highly dynamic behavior of U in stream water is caused by complex interactions of natural and anthropogenic processes differing in frequency and magnitude. Such processes include diurnal and seasonal photosynthesis cycles, rain events, and pumping regimes of mines discharching uraniferous effluents.
