Three major geological events in the distant past have shaped the present drainage systems of Peninsular India: Subsidence of the western flank of the Peninsula leading to its submergence below the sea during the early tertiary period. Generally, it has disturbed the symmetrical plan of the river on either side of the original watershed. Upheaval

Older than the Himalayan one. Evident from the broad, largely-graded shallow valleys, and The Western Ghats running close to the western coast act as the water divide between the major Peninsular rivers, discharging their water in the Bay of Bengal and as small rivulets joining the Arabian Sea. Most of the major Peninsular rivers except

The Brahmaputra, one of the largest rivers of the world, has its origin in the Chemayungdung glacier of the Kailash range near the Mansarovar lake. Tibet, where it is known as the Tsangpo, which means the purifier. ‘The Rango Tsangpo is the major right-bank tributary of this river in Tibet. Enters India west of Sadiya

The most important river of India both from the point of view of its basin and cultural significance. It rises in the Gangotri glacier near Gaumukh (3,900 m) in the Uttarkashi district of Uttarakhand. Here, it is known as the Bhagirathi. At Devprayag, the Bhagirathi meets the Alaknanda; hereafter, it is known as the Ganga.

One of the largest river basins of the world, covering an area of 11,65,000 sq. km (in India it is 321, 289 sq. km and total length of 2,880 km (in India 1,114 km). Originates from a glacier near Bokhar Chu (31°15′ N latitude and 81°40′ E longitude) in the Tibetan region at an altitude

The Himalayan drainage system has evolved through a long geological history. It mainly includes the Ganga, the Indus and the Brahmaputra river basins. rivers of this system are perennial. These rivers pass through the giant gorges carved out by the erosional activity carried on simultaneously with the uplift of the Himalayas. The course of these

The flow of water through well-defined channels is known as drainage ‘and the network of such channels is called a drainage system. Is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing and the periodicity of the flow. A river drains the water collected from a

This article cleverly drills down into the nitty-gritty of the region and recognizes that there are two major island groups in the Bay of Bengal: 1) Andaman & Nicobar Islands and 2) The Lakshadweep Islands. The Bay of Bengal island groups consists of about 572 islands/islets. These are situated roughly between 6°N-14°N and 92°E -S4°E.

India is a country on the coastal plains on the south-western fringe of Asia. The Indian subcontinent lies on a thin slice of land between the Arabian Sea and the Bay of Bengal. On the basis of the location and active geomorphological processes, it can be broadly divided into two: fi) the western coastal plains:

The Great Indian Desert is a part of the greater Thar Desert, which spans through India into Pakistan. This vast desert encompasses the western states of Gujarat, Rajasthan, Haryana, Punjab, and Delhi.  It is because of these characteristic features that this is also known as Marusthali. The Luni river flowing in the southern part of
