Question

Describe the various drainage patterns of rivers. give some examples of Indian rivers

Answer 1

A drange pattern can be defined in the shadow of topographical future from which stream get a run of the floor and groundwater flow which can be divided by drop for proper graphic various called a watershed

Answer 2

Explanation:

The drainage pattern of a river reveals its flow to form distributaries, tributaries, lakes and how it drains into the main basin. All the rivers rise in the mountains and flow into the sea, but drain several areas on its way. The pattern formed by the branching of distributaries and formation of different water bodies gives rise to different patterns.

The Indian rivers are divided into two major groups - "The Himalayan Rivers" and "The Peninsular rivers", where the Himalayan Rivers are perennial and have water throughout the year. And peninsular rivers are dependent on rain.

The 4 types of drainage pattern common in India which are  

• Dendrite pattern - where river follows the direction of the slope of the terrain (land) or it's stretch. The stream spreads and breaks at highlands and lowlands in plains and its tributaries form the pattern of a branched tree. This is called a dendrite pattern. For example: The tributary of Ganga River.
• Trellis pattern - In this, two streams running parallel to each are intersected by their tributaries at a right angle as they move through hard rocks on one side and soft rocks at the other side. For example:  Rivers in the upper course of the Himalayas like Alaknanda, Narmada, and Tapi.
• The rectangular drainage pattern is developed when they are surrounded by extremely hard rocks that show many bends at right angles. For example:  Rivers in the Vindhya Range.
• The radial pattern is observed in the Amarkantak Mountain. Here, the stream flows in all direction from the central peak just like spokes of a wheel. The originating rivers Mahanadi, Narmada, and son from this mountain point flow in a different direction forming a radial pattern.
