Zusammenfassung:
A quantification of bedrock erodibility under fluvial impact erosion is required for various tasks in geomorphology, landscape evolution, and hydraulic engineering. However, it is challenging to measure in the field. Various proxy methods for easy measurement have been suggested and applied, but none of these has been benchmarked against high-quality data from the laboratory or field. We have collected field and laboratory data on erodibility using erosion mills as well as proxy data from the Schmidt hammer, Mohs' hardness, and the Annandale and Selby methods for 18 different lithological units.
