What are distributaries ?

Distributaries are smaller streams or rivers that branch off from a main river and flow away from it, usually found in river deltas or floodplains. Unlike tributaries, which bring water into a main river, distributaries distribute water away from it, typically toward a larger body of water like an ocean, sea, or lake.

Distributaries play a crucial role in shaping the landscape and supporting ecosystems in delta regions. They help in sediment deposition, irrigation, and formation of fertile land suitable for agriculture.

Key Characteristics of Distributaries

Feature	Description
Direction of Flow	Away from the main river
Common Locations	River deltas, floodplains
Function	Distribute water and sediment to other areas
Impact	Helps form deltas, fertile soil, and supports biodiversity
Opposite of	Tributaries (which flow into a main river)
Common Examples	Hooghly River (from Ganges), Atchafalaya River (from Mississippi River)

Importance of Distributaries

Agriculture: Deposits nutrient-rich sediments, ideal for farming.

Flood Control: Spreads water over a wider area, reducing flood intensity.

Ecological Balance: Supports wetland ecosystems and biodiversity.

Navigation and Transportation: Often used for local transport and trade.
