The flow of water through well-defined channels is known as 'drainage' and the network of such channels is called a 'drainage system'. The drainage pattern of an area is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing, and the periodicity of the flow.
(i) The drainage pattern resembling the branches of a tree is known as “dendritic” the examples of which are the rivers of the northern plain.
(ii) When the rivers originate from a hill and flow in all directions, the drainage pattern is known as ‘radial’. The rivers originating from the Amarkantak range present a good example of it.
(iii) When the primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as a ‘trellis’.
(iv) When the rivers discharge their waters from all directions in a lake or depression, the pattern is known as ‘centripetal’.
