Question

how do the himalayan rivers perform erosional activities and form depositional features . explain with the help of diagram​

Answer 1

The "Himalayan rivers" have long courses from their source to the sea. Through their high courses, they perform extensive erosion activities and carry large amounts of silt and sand, as they pass downstream. Melting glaciers raise water flow, which transports a great deal of sediment &takes away the essential nutrients from the plains.

Explanation:

• In the upper course,the river flows with "great speed" from "higher to lower" levels. This cause erosion.
• In the "middle" and the "lower course" they carry plenty of sediments such as sand & silt. Hence, the speed slows down
• In addition, the absence of "slope" in the "lower course" leads to deposition & formation of different features.
• This is, In the "middle" & the "lower" courses, these rivers form ox-bow lakes, meanders & several other "depositional features" in their floodplains.

Answer 2

The himalayan rivers create various erosional features and form depositional features like flood plains.

Explanation:

• The Himalayan river system is characterized by the Ganga, Indus, and the Brahmaputra rivers and of which Ganga is the most pious river system in India.

• The river flows down from the Gangotri glacier in the Himalayas and descends to the plains in the way it forms gorges canyons and down cuts the valleys.

• The river performs intense erosional activity in the upper reaches due to its youthful stage. It has high energy and high capacity to carry huge loads of silts and sand.  

• The river in its middle stage or mature stage starts to meander and this results in erosion and deposition of the silt and other sediments brought by the river such as waterfalls,

• In the lower stage or older stage the river density of water is less and starts to deposit its load at places formation of Ox bow lake and then delta.
