Submarine canyons associated with alternating sediment starvation and shelf-edge wedge development: Northern KwaZulu-Natal continental margin, South Africa

► Seismic and bathymetric data are presented from the northern KwaZulu-Natal continental margin. ► Delivery of sediment to the shelf edge-wedge drives submarine canyon development. ► Sediment starvation has ameliorated more elaborate incision episodes.
