Modeling postbreakup landscape development and denudational history across the southeast African (Drakensberg Escarpment) margin

Van der Beek, Pieter A; Summerfield, Michael; Braun, Jean; Brown, Roderick William; Fleming, Alastair


We employ a numerical surface processes model to study the controls on postbreakup landscape development and denudational history of the southeast African margin. Apatite fission track data, presented in the companion paper, suggest that the Drakensberg Escarpment formed by rapid postbreakup river incision seaward of a preexisting drainage divide, located close to its present position, and subsequently retreated at rates of only ∼100 m m.y.-1. Numerical modeling results support such a scenario...[Show more]
