Abstract

Geomorphological and sedimentological considerations are used to evaluate the interaction of wind and water in shaping contemporary lunette processes. It is considered that like other pans in the area, groundwater activity influences pan floor sediment avaibility and transport, that the present highly seasonal climatic regime permits the interaction of aeolian transport of sediment to the dune and its return to the pan floor by water during storm events, creating a cycling process favoured by sedimentary properties that promote surface runoff
