Models of bedrock river incision, whether … Models of bedrock river incision, whether stream-power or mechanistically based, incorporate approximations of bedrock susceptibility to erosion. One or more parameters for a specific basin, lithology or outcrop may be estimated, and related to erodibility, as well as abrasion and plucking characteristics. However, choosing those parameters requires information of bedrock properties, which are either approximated or measured. Field and flume measurements are currently used to obtain physical bedrock properties that can be used for those models. Most studies focus on either field or flume measurements, but it is unclear whether their results are interchangeable. Therefore, we compare field measurements of compressive strength obtained with the Schmidt hammer and fracture intensity and block size with macro-abrasion and attrition rates obtained by flume measurements. We aim to discuss their possible meaning in terms of physical erosion processes and their use for bedrock river incision modeling.r use for bedrock river incision modeling. +
