Sediment Dynamics, Waipaoa Basin

The Waipaoa Basin on the east coast of New Zealand's North Island has one of the highest contemporary sediment yields in the world. The place is a challenge cosmogenically as there is little quartz and what quartz there is, is very fine grain. We used a network analysis approach and analysis of both in-situ and meteoric 10-Be to model both erosion rates and the spatial distribution of erosion.
