In 2012 we lost Jean Jacques Peters, former engineer of Flanders Hydraulics Research (1964 till 1979) and international expert in sediment transport, river hydraulics and morphology. As a tribute to him we have created potamology, a virtual memorial archive whose aim is to preserve and disseminate his way of thinking and his morphological approach to river problems all over the world.This archive provides four modules, each with its specific information set relevant to Peters’ work. Where available and if not confidential, there will also be access to the full text. In dialogue with Peters’ family we continue to make his life’s work accessible.
Cyclic steps: a phenomenon of supercritical shallow flow from the high mountains to the bottom of the ocean

Cyclic steps constitute a characteristic bedform of Froude-supercritical shallow flow over an erodible bed. They are long-wave features that are bounded by hydraulic jumps and migrate upstream. They can be seen in alluvial streams, stream in cohesive sediment, bedrock streams, and on the seafloor in response to turbidity currents. Recent progress in the modeling of cyclic steps is summarized.
