Notes on Rivers of India

This easily explains why almost every major Indian city is located along a river. These rivers also play a vital role in Hinduism and are considered by many Hindus in the country to be sacred.  Seven major rivers and their numerous tributaries form the Indian Ocean system. The largest river system flows into the Bay of Bengal; however, some of its rivers flow through the western part of the country and head east of the Himachal Pradesh region to the Arabian Sea. Parts of Ladakh, northern parts of the Aravalli range and parts of the Thar Desert have deep inland trenches. All the major rivers in India are derived from one of the following major waterfalls: Aravalli distance Himalayan and Karakoram level Sahyadri or Western Ghats in western India Vindhya and Satpura range and Chotanagpur plateau in central India T...

Drainage System of India U.P.S.C Drishti I.A.S

Water Transport: The flow of water through well-defined canals is known as ‘canals’ and the network of such channels is called the ‘drainage system’. Drainage pattern: Refers to the surface water system, especially rivers and lakes. The drainage system depends on factors such as slope, geological composition, the volume of water, and water velocity. Types of drainage patterns Dendritic drainage pattern: It is a very common method and resembles a branching pattern of tree roots. A dendritic pattern develops as the river path follows the local slope. The pattern grows in areas where the rock beneath the stream has no specific structure and can be eroded evenly on all sides. Tributaries join large streams at intense angles (below 90 °). Eg. Rivers of the northern plains; Indus, Ganga, and Brahmaputra. Compatible drainage pattern: It grows in regions of intertwined areas, long where there is a pronounced slope. The tributary flow usually expands in the same direction following the upper sl...
