Self-limitation of sand storage in a bedrock-canyon river arising from the interaction of flow and grain size
David J. Topping, Paul E. Grams, Ronald E. Griffiths, David J. Dean, Scott Wright, Joel A. Unema
2021, Journal of Geophysical Research Earth Surface (126)
Bedrock-canyon rivers tend to be supply limited because they are efficient transporters of sediment and not because the upstream supply of sediment is small. A byproduct of this supply limitation is that the finer alluvium stored in these rivers has shorter residence times and smaller volumes than...
