Abstract

This paper presents an effort to link a field-based study with surface exposure dating techniques to understand river longitudinal profile evolution. The study was aimed at improving the understanding of the rates and processes governing bedrock channel incision. Samples to be analysed for cosmogenic isotopes were collected along a river profile and both radionuclide and stable nuclide concentrations were measured in the rocks. Specifically the nuclides [10]Be, [26]Al,[36]Cl,[21]Ne and [3]He allow direct quantification of exposure ages and erosion rates and permit quantitative assessment of the processes operating in the studied landscape
