The cover effect in fluvial bedrock erosion is a major control on bedrock channel morphology and long-term channel dynamics. Here, we suggest a probabilistic framework for the description of the cover effect that can be applied to field, laboratory,...

Bed load tracer mobility in a mixed bedrock/alluvial channel (2017)
Journal Article

The presence of bare or partially-covered rock in an otherwise alluvial river implies a downstream change in transport capacity relative to supply. Field investigations of this change and what causes it are lacking. We used two sets of magnet-tagged... Read More about Bed load tracer mobility in a mixed bedrock/alluvial channel.

Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel (2017)
Journal Article
Ferguson, R., Sharma, B., Hardy, R., Hodge, R., & Warburton, J. (2017). Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel. Water Resources Research, 53(3), 2278-2293. https://doi.org/10.1002/2016wr020233

Assumptions about flow resistance in bedrock channels have to be made for mechanistic modeling of river incision, paleoflood estimation, flood routing, and river engineering. Field data on bedrock flow resistance are very limited and calculations gen... Read More about Flow resistance and hydraulic geometry in contrasting reaches of a bedrock channel.
