Introduction How Rivers Run Stories Value Of A River What We Can Do
Shape of a River - Geomorphology
Description (pg 1 of 2)

What distinguishes a mountain stream from a pasture brook of similar size? Why does one rush quickly while the other eases slowly though riffles and bends? Why do some streams crash over falls and steep rapids, while others flow swiftly over riffles of sorted cobble? Why are so few rivers straight and so many, large and small, settled into a pattern of alternating bends?

The answers to these questions lie in the realm of geomorphology, the study of the geologic forces that form the landscape, creating streams and continuing to shape them largely through the action and effects of moving water.
