This paper is our attempt to synthesize a portion of the vast literature concerning the effects of landscape evolution on channel changes in gravel-bed rivers. More precisely, we try to understand how changes in the boundary conditions of an alluvial plain lead to channel metamorphosis as defined by Schumm in 1969 between two end-member patterns or rivers: highly sinuous meandering and braided.
