Drainage patters: dendritic, rectangular, trellis, etc.
What is dendritic drainage?
"Tree-like" pattern of stream network
What is a Deranged drainage?
Chaotic arrangement of channels connecting small lakes and marshes, typical of landscapes following the retreat of ice sheets
what is rectangular drainage?
Forms in a faulted and jointed landscape, which directs steams courses in patterns of right-angled turns
When does dendritic drainage form?
Forms when you have rocks of uniform resistance to weathering & moderate slopes
what is annular drainage?
Produced by structural domes (domes formed by folding of rocks in 2D), with concentric patterns of rock strata guiding stream courses
what is radial drainage?
Produced when stream flow off a central peak or dome, such as a volcanic mountain
what trellis drainage?
Typical of dipping (monocline) or folded topography with differential weathering
