Short summary

The concentration of cosmogenic ¹⁰Be is typically measured in the sand fraction of river sediment to estimate catchment-average erosion rates. Using the sand fraction in catchments where the ¹⁰Be concentrations differ per grain size could potentially result in biased erosion rates. In this study we investigated the occurrence and causes of grain size-dependent ¹⁰Be concentrations and identified the types of catchments which are sensitive to biased catchment-average erosion rates.
