Ganga, Indus & Brahmaputra – Himalayan Rivers

Ganga river Brahmaputra Indus Chambal

Drainage Systems Based on Origin

Himalayan Rivers

  • Those are Perennial rivers
  • Indus, the Ganga, the Brahmaputra, and their tributaries.
 

Peninsular Rivers

 
 
Drainage Systems Based on Orientation to the sea

Bay of Bengal drainage

  • Rivers that drain into the Bay of Bengal
  • East flowing rivers
  • 77% of the drainage area of the country is oriented towards the Bay of Bengal
  • 90% of the water drains into the Bay of Bengal
 

Arabian sea drainage

  • Rivers that drain into the Arabian sea
  • West flowing rivers
  • 23% of the drainage area of the country is oriented towards the Arabian sea
  • Less than 10% of the water drained into the Arabian Sea
 
 

Himalayan River systems

  • The Indus, the Ganga, and the Brahmaputra comprise the Himalayan river systems.
  • Himalayan Rivers existed even before the formation of Himalayas (Antecedent Drainage)
  • They were flowing into the Tethys Sea.
  • These rivers had their source in the now Tibetan region.
  • The deep gorges of Indus, Satluj, Brahmaputra, etc. indicate that these rivers are older than the Himalayas.
  • They continued to flow throughout the building phase of the Himalayas
  • Their banks rising steeply while the beds went lower and lower due to vertical erosion
  • In upper reaches (Youthful stage) they form Gorges, V-shaped valleys, rapids, waterfalls, truncated spurs, etc.
  • In plain areas or middle part (Mature stage) they form depositional features like flat valleys, ox-bow lakes, flood plains, braided channels, and deltas near the river mouth.
  • Over the plains, they display a strong meandering tendency and shift their courses frequently

Evolution of the Himalayan Drainage System

  • A mighty river called Shiwalik or Indo-Brahma traversed the entire longitudinal extent of the Himalaya from Assam to Punjab and onward to Sind
  • It discharged into the Gulf of Sind near lower Punjab
  • It was during the Miocene period some 5-24 million years ago.
  • Evidence – The remarkable continuity of the Shiwalik and its lacustrine origin and alluvial deposits consisting of sands, silt, clay, boulders, and conglomerates support this viewpoint.
  • It is opined that in due course of time Indo–Brahma river was dismembered into three main drainage systems
    1. Indus and its five tributaries in the western part;
    2. Ganga and its Himalayan tributaries in the central part
    3. Stretch of the Brahmaputra in Assam and its Himalayan tributaries in the eastern part.
  • The dismemberment was probably due to the Pleistocene upheaval in the western Himalayas
  • It includes the uplift of the Potwar Plateau (Delhi Ridge)
  • Potwar Plateau acted as the water divide between the Indus and Ganga drainage systems.
  • Malda gap is the area between the Rajmahal hills and Meghalaya plateau
  • It diverted the Ganga and the Brahmaputra systems to flow towards the Bay of Bengal.
  • During the mid-Pleistocene period, it came into excessed
