    Most of the rivers of Namibia reaching the sea north of the Central Sea of Dunes, display fan-shaped deposits at their mouths. They are referred to as arid deltas in this study. The arid delta which occurs at the mouth of the Kuiseb River constitutes its central theme. The aim of the study was to formulate a model to postulate the idealised formation of arid deltas from the evidence present in known delta forms. According to it three phases characterise the formation of arid deltas: (1) Sporadic deposition at the mouth of an episodic river. (2) A progressive extension of the delta front during episodes of sedimentation and the regressive removal of it by wave action. (3) The landward accumulation of a relatively small sediment prism.
