Study Notes
Drainage Systems in India
- Drainage describes the river system of an area.
- Streams flow together to form a main river.
- The area drained by a single river system is a drainage basin.
- An elevated area, like a mountain or upland, separates drainage basins. This is called a water divide.
- Indian drainage systems are categorized by the physical features of the subcontinent.
- Two main groups exist: Himalayan rivers and Peninsular rivers.
- Himalayan rivers are perennial (flowing year-round) and originate in the mountains, receiving water from rain and melted snow.
- The Indus and Brahmaputra are major Himalayan rivers that carve gorges through the mountains.
- Peninsular rivers are seasonal, with flow depending on rainfall.
- They have shorter courses and originate in the central highlands, flowing towards the west or Bay of Bengal.
- The world’s largest drainage basin is the Amazon river basin.
Himalayan Rivers
- The Indus, Ganga, and Brahmaputra are major Himalayan rivers.
- These rivers have many large tributaries.
- The Indus rises in Tibet, flowing west through India to the Arabian Sea.
- The Ganga rises in the Himalayas, flowing east to the Bay of Bengal.
- The Brahmaputra originates in Tibet, flowing east through India and joining the Ganga before merging in Bangladesh into the Bay of Bengal.
Peninsular Rivers
- Peninsular rivers primarily rise in the Western Ghats and flow eastward into the Bay of Bengal.
- These include the Godavari, Krishna, Kaveri, Mahanadi, Narmada, and Tapi.
- The Narmada and Tapi are the only major rivers flowing west.
- Many Peninsular rivers are seasonal due to dependence on rainfall.
River Systems
- Tributaries are smaller streams that feed into larger rivers.
- A river system consists of a main river and its tributaries.
Drainage Patterns
- Different rivers have unique drainage patterns affected by the topography and geology.
- Drainage patterns like dendritic, radial, and trellis are influenced by the underlying terrain.
