Drainage Systems and River Basins Quiz

Drainage Systems in India

• Drainage refers to the river system in an area, with small streams merging to form a main river that eventually drains into a large body of water.
• The area drained by a single river system is called a drainage basin.
• A water divide, such as a mountain or upland, separates two drainage basins.
• In India, the rivers are divided into two major groups: the Himalayan rivers and the Peninsular rivers.
• The Himalayan rivers are mostly perennial, meaning they have water throughout the year.
• The Peninsular rivers differ from the Himalayan rivers in several ways.
• The Himalayan rivers originate from the Himalayan region, while the Peninsular rivers originate from the Peninsular region.
• The Peninsular rivers may not be perennial and may have seasonal variations in water flow.
• The drainage pattern in India is influenced by the physical geography of the country.
• The physical map of India shows the convergence of small streams into main rivers, which then drain into lakes, seas, or oceans.
• The drainage basins in India are separated by water divides, which are elevated areas like mountains or uplands.
• The drainage system in India plays a crucial role in shaping the country's landscape and influencing its water resources.
