Question

Specified area where water reaches a river:
1. Watershed
2. River Basin
3. Catchment area
4. Water separator

Answer 1

Correct Answer - Option 1 : Watershed

The correct answer is Watershed.

• The river and its tributaries together form the river system.
• The area where all the water gets to the river system is called the drainage basin (watershed).
• The river goes through the young stage, the mature stage, and the old stage in its lifespan.
• These stages are related to the slope of its alluvial.
• In its youth and old age, the river forms landforms in its cascade.
• The area that provides water (surface and groundwater) to the river is called the "river basin".
• This is the area that can be called the body of a river.
• Catchment area-
  • The entire area whose flowing water reaches a river or stream is called the Catchment area of that river.
• River Basin -
  • All the land area (catchment area) as far as water flows through a river and its tributaries.
• Watershed-
  • It is a land area that drains all the streams, rainfall, and rivers to a common outlet.​
