Discussion on Forming Conditions of the Alluvial River Patterns

It is a general frame of fluvial process that flows form river channels and the channels are constrained by flows. The relationship between river patterns and river bend curvatures shows that rivers with large bend curvatures are of narrow and deep channels and those with shallow and wide channels are always straight. Therefore, a cross-sectional shape of the river channel determines the plan form of river. Although bigger difference is observed in the different combinations of water and sediment, a meandering channel may be developed so long as a narrow and deep channel is formed.
