DRAINAGE SYSTEMS IN INDIA

The drainage systems of India are mainly controlled by the broad relief features of the sub-continent. The rivers of India are broadly classified into two major groups

  •        The Himalayan rivers
  •       The Peninsular rivers
  • Apart from originating from two major physiographic regions of India, the Himalayan and the Peninsular rivers are different from each other in many ways.

    The Himalayan Rivers: Most of the Himalayan rivers are perennial, which means that they have water throughout the year. These rivers receive water from rain as well as from melted snow from the high mountains. The Indus and the Brahmaputra originate from North of the mountain ranges. They have cut through the mountains, making gorges. The Himalayan rivers have long courses from their source to the sea. These rivers perform intensive erosion activity in their upper course and carry huge loads of silt and sand. These rivers form meanders, Ox-bow Lakes and other depositional features during their middle and lower courses in the floodplains. These rivers have well developed deltas.The Peninsular Rivers: These are seasonal rivers as their flow is depend rainfall. During the dry season, the large rivers even the flow of water in their channel.  Himalayan. The Peninsular rivers have shorter and shallower courses compared to their Himalayan counterparts Peninsular rivers originate in the Western Ghats towards the Bay of Bengal.Some Features Made by Rivers•    Gorges: Deep narrow passages with steep rocky sides through which rivers may flow.•    Ox-bow Lake:  A crescent-shaped lake formed when a meander of a river or stream is cut off from the main channel.•    Deltas: Triangular shaped alluvial deposits at the mouth of rivers where they enter the sea.
