Study Notes
Drainage System Overview
- Drainage refers to the river system within a specific area.
- Small streams converge to form a main river, which eventually flows into larger bodies of water (lakes, seas, oceans).
- The area served by a single river system is known as a drainage basin.
Water Divide
- Elevated terrains, like mountains or uplands, demarcate two distinct drainage basins.
- This elevated region is termed a water divide, which plays a crucial role in directing water flow and defining watershed boundaries.
Types of Rivers in India
- Indian rivers are categorized into two principal groups based on their origin:
- Himalayan Rivers
- Peninsular Rivers
- Himalayan rivers typically maintain a perennial flow, meaning they have water year-round, a result of consistent snowfall and glacial melt.
Differences Between River Types
- Himalayan and Peninsular rivers exhibit notable differences in characteristics and behavior due to their distinct geographical origins.
