dc.description.abstractMost 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.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die meeste Namibiese riviere wat noord van die Sentrale Duinsee in die see uitmond, vertoon by hul mendings, waaiervormige afsettings waarna daar in die studie as ariede deltas verwys word. Die Kuisebdelta het ook so 'n ariede delta en vorm die sentrale tema van die studie. Die doel van die studie was om uit die bekende deltavorme 'n model af te lei wat sou postuleer hoe ariede deltas ideaalweg kan ontstaan. Hiervolgens ontstaan ariede deltas in drie fases: ( 1) sporadiese afsetting by die mending van 'n episodiese rivier; (2) 'n progressiewe uitbou van die deltafront tydens episodes van sedimentasie en die regressiewe verwydering daarvan deur branderaksie; (3) die landwaartse akkumulering van 'n betreklik klein sedimentprisma.af_ZA
