The Himalayan and Peninsular drainage systems in India are two distinct river systems with different characteristics. Here are the key differences between the two:
1. Origin:
- Himalayan Drainage System: The Himalayan rivers originate from the Himalayan mountain range, which lies in the northern part of India and extends across several neighboring countries like Nepal, Bhutan, and Tibet.
- Peninsular Drainage System: The Peninsular rivers originate from the plateau region of the Indian Peninsula, primarily from the Western Ghats and the Eastern Ghats.
2. Direction and Flow:
- Himalayan Drainage System: The Himalayan rivers flow in a generally north-south direction, originating from the Himalayas and ultimately draining into the Bay of Bengal. These rivers have a relatively steep gradient, resulting in fast-flowing and highly erosive characteristics.
- Peninsular Drainage System: The Peninsular rivers flow in a west-east direction and drain into the Arabian Sea, the Bay of Bengal, or inland salt lakes. These rivers have a comparatively gentler gradient and exhibit slower flow rates.
3. Length and Size:
- Himalayan Drainage System: The Himalayan rivers are generally longer and larger in size compared to the Peninsular rivers. Rivers like the Ganges, Brahmaputra, and Yamuna are major examples of the Himalayan drainage system.
- Peninsular Drainage System: The Peninsular rivers, such as the Godavari, Krishna, and Mahanadi, are relatively shorter and smaller compared to their Himalayan counterparts.
4. Formation of Valleys:
- Himalayan Drainage System: The Himalayan rivers have carved deep valleys and gorges due to their high erosive power. These valleys are characterized by steep slopes and are often associated with spectacular landscapes.
- Peninsular Drainage System: The Peninsular rivers have formed broader valleys due to their comparatively less erosive nature. These valleys are generally wider and flatter compared to the steep valleys of the Himalayan rivers.
5. Seasonal Variation:
- Himalayan Drainage System: The Himalayan rivers exhibit significant seasonal variation in their water flow due to the melting of snow and glaciers during the summer months. This results in a distinct pattern of flood and drought occurrences.
- Peninsular Drainage System: The Peninsular rivers, being primarily rain-fed, also experience seasonal variations in water flow. However, their flow patterns are more influenced by the monsoon rains.
These are some of the key differences between the Himalayan and Peninsular drainage systems in India. Understanding these differences helps in comprehending the distinct characteristics and geographical significance of these river systems.
