Figure 1. Umbum Creek, western Lake Eyre, Central Australia showing a sandy terminal splay complex dominated by a single main fluvial channel downstream of an incised meanderbelt. Note the pooling of water in the fluvial channels updip of the frontal splay complex which is topographically higher than the base of the main fluvial channel. The white sediment in the foreground is a thin veneer of salt extending into the playa lake.
