Question

explain the drainage patterns of rivers

Answer 1

In geomorphology, drainage systems, also known as river systems, are thepatterns formed by the streams, rivers, and lakes in a particular drainagebasin. They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land.

Answer 2

The Dendritic pattern develops where the river channel follows the slope of the terrain. The stream with its tributaries resembles the branch of a tree , thus the name Dendritic. A river joined by its tributaries , at approx right angles , devlops a Trellis pattern. A Trellis drainage pattern develops where hard and soft rocks exist parallel to each other. A rectangular drainage pattern develops on a strongly joined rocky terrain.
