River Basin Erosion Dynamics

Going from isotopic concentration to erosion rate (or index) In situ 10 Be (10 Be₁): • Isotopic concentration of the sediment is compared to the rate of production, and the difference is attributed to land surface lowering Meteoric 10Be (1ºBem): The export rate of 10Bem on sediment is compared to the delivery rate, and a ratio is made >1 indicates more is leaving than being delivered <1 indicates more is being delivered than leaving IN OUT
