Strath formation is a continuous process of response to long‐term uplift, and its occurrence varies spatially along a river depending on stream power, and hence position, upstream.

Aaron copland at the river pdf merger. Middle to upper reaches of each river are dominated by the effects of long‐term uplift, primarily lateral and Vertical erosion and formation of steep, unpaired strath terraces exposed only upstream of the depositional wedge.
