Cyclic steps: review and aggradation-based classification

A Slootman, MJB Cartigny - Earth-Science Reviews, 2020 - Elsevier
Cyclic steps are a type of upper flow-regime bedform consisting of trains of upstream-and
upslope-migrating bed undulations. The overriding flow is characterised by a series of …
