in the Taroko gorge, eastern Central Range, Taiwan. Without considering gorge wall retreat, the estimates therefore represent maximum incision rates. The long-term gorge development governed by tectonic uplift is superimposed by short-term variations in incision
rates caused by climatic or regional tectonic changes.

index appear primarily to reflect tectonic patterns and transient adjustment to those patterns by channel networks. Climate and lithology do not appear to exert first-order controls on patterns of basin-averaged erosion rates in the Bolivian Andes.

The AA. dated caves in canyon walls, Sierra Nevada, using Al 26/Be 10 dating to document rates of river incision into bedrock, a primary means by which landscapes respond to tectonic forcing. They also measured nuclide concentrations in bare bedrock
