Abstract

This study investigates the local-scale generation and movement of dust in the seasonal swamps of the Okavango Delta, with a view to examining possible transfer of material between flood plains and islands. The contrasts in dust loads between islands and flood plains suggests that there is a net transfer of dust from flood plains to islands, but it was not possible to quantify this transfer. It is evident, however, that flood plains experience net erosion and islands net aggradation. A strong seasonality in dust loads is observed. This also coincides with peak seasonal flooding in the delta, and only non-inundated flood plains are capable of generating dust
