The Atlantic Margin of Southern Africa Between Latitude 17° South and the Cape of Good Hope

  • H. Martin

Abstract

The 2000-km coast of southwestern Africa from lat 17° S to the Cape of Good Hope has few sizeable embayments. The only two bays are the Saldanha Bay to the north of Cape Town, which is enclosed by low granite hills, and Walvis Bay, which is protected by a long sand spit. From this nearly unbroken coast the land rises eastwards in wide pediplains, surmounted by single hills or ranges of hills. The pediments slope towards the major river systems and either intersect on the broad interfluves or terminate against hills, where these form the interfluves. The pediments are best developed in the desert belt to the north of the Orange River. In the winter rain belt to the south of the River the pediments give way to a rolling topography of low hills. The pedimented interfluves rise eastwards with gradients of about 1: 100 to 1: 80 reaching elevations of 1000–1200 m at distances of about 140 km from the coast where the dissected mountain belt of the Great Escarpment begins. The major rivers have cut deep gorges into the pedimented surfaces.
