Study Notes
Drainage Basin and Indian Rivers
- A drainage basin is an area of land that drains water into a particular river or lake, and is bounded by a watershed or water divide.
Classification of Indian Rivers
- Indian rivers are divided into two major groups: Himalayan rivers and Peninsular rivers.
Water Divide
- A water divide is a ridge or highland that separates two drainage basins, and is the boundary beyond which water flows into different rivers or lakes.
Characteristics of Himalayan and Peninsular Rivers
- The main difference between Himalayan rivers and Peninsular rivers is their source, flow, and seasonal variability: Himalayan rivers are perennial, fed by melting snow and glaciers, and have a high flow even in the lean season, whereas Peninsular rivers are seasonal, fed by rainwater, and have a low flow during the lean season.
Perennial Rivers
- In the context of rivers, perennial means a river that flows throughout the year, and has a steady and consistent supply of water, often due to a constant source of water such as melting snow or glaciers.
