Question

. What is a river/drainage basin?​

Answer 1

Answer:

DRAINAGE BASIN

A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water.

Explanation:

•                     The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface
• Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.

For example, the total area drained by the Mississippi River constitutes its drainage basin, whereas that part of the Mississippi River drained by the Ohio River is the Ohio’s drainage basin

• The drainage basin acts as a funnel by collecting all the water within the area covered by the basin and channelling it to a single point.
• Each drainage basin is separated topographically from adjacent basins by a perimeter, the drainage divide, making up a succession of higher geographical features (such as a ridge, hill or mountains) forming a barrier.
• The Ganga the Ganga Brahmaputra basin is the largest river basin in India.
• Amazon River basin is the largest river basin in the world which is situated at South America.
