Pattern Description Controlling influences
Dendritic Random, tree-like branches Flat-lying sedimentary or homogeneous rock
Trellis Long subsequent streams with short tributaries Developed in folded rocks of varying strengths
Multibasinal, Centripetal Stream flow toward one or more central region Interior drainage (sinks), Karst
Deranged Interrupted by swamps and lakes Glaciated regions
Annular Accurate subsequent stream with short tributaries Eroded dome or basin containing rocks of varying resistances
Radial Tributaries radiate away from a central region Central highland
Rectangular Tributaries make right angle bends Jointed or faulted bedrock
Barbed One or more tributaries enter at an angle >90% Captured drainage
Braided Multiple interconnected channels separated by braid bars Sediment load
