When Does the Concavity Index Constrain Stream Power Parameters? The concavity index and m/n are not equivalent when there is spatial variation in relative rock uplift rate We present a new method to measure m/n that accounts for variation in rock uplift and e...

New research out in JGR Earth Surface presenting a new method to infer stream power parameters when there is spatial variation in rock uplift and erodibility in landscapes. Particular focus on how gradients in rock uplift and erodibility go unnoticed if working with simplified assumptions!
