What is the river pattern? Write about different river patterns?
Answers
Answer:
A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material. That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.
The river pattern is also termed as drainage system of the river that naturally forms due to the topography of the lands.
There are various types of drainage systems, among which Dendritic, Trellis, Radial and Parallel drainage systems are most prominent.
Dendritic pattern resembles a branched tree while the river flows over a land with uniform rocks.
Trellis pattern is rectangular in shape and forms over the land having alternate layers of hard and soft rocks.
Radial pattern forms when the river jumps from a high position to different directions like the spokes of a wheel.
Parallel pattern forms when multiple streams flow parallel to each other.
