When rivers discharge their waters from all directions in a lake/depression, the pattern is known as ‘centripetal’. This drainage pattern is even called endorheic drainage. For instance, Loktak lake in Manipur.When the primary tributaries of rivers travel parallel to each other and secondary tributaries join them at 90 Degree, the pattern is known as ‘trellis’. For instance, rivers in the upper part of the Himalayan part and the old folded mountains of the Singhbhum (i.e. Chotanagpur Plateau) have drainage of trellis pattern. The dendritic type of pattern develops where the river channel follows the slope of the terrain. When the drainage pattern resembles the branches of a tree, it is known as “dendritic” the examples of which are the northern plain rivers. This is the most common stream pattern. The radial type of pattern develops when streams flow in distinct directions from a central peak or a dome-like structure. For instance, the rivers such as the Narmada, Son & Mahanadi originating from Maikal Hills flow in various directions and are good examples of a radial pattern.
