The Ganges Basin drains 1,square-kilometresq mi and supports one of the world's highest densities of humans. The average depth of the river is 52 feet 17 mand the maximum depth, feet 33 m. Course[ change change source ] The river starts from a glacier called Gangotri Glacier, which is in the Garhwal region in Himalayas.
Bhagirathi River at Gangotri. Devprayagconfluence of Alaknanda right and Bhagirathi left rivers, beginning of the Ganges proper. The headstreams and rivers are labelled Ganga project italics; the heights of the mountains, lakes, and towns are displayed in parentheses in metres.
The main stream of the Ganges begins at the confluence of the Bhagirathi and Alaknanda rivers in the town of Devprayag in the Garhwal division of the Indian state of Uttarakhand.
The Bhagirathi is considered to be the source in Hindu culture and mythology, although the Alaknanda is longer, and, therefore, hydrologically the source stream. The five confluences, known as the Panch Prayagare all along the Alaknanda. They are, in downstream order, Vishnuprayagwhere the Dhauliganga joins the Alaknanda; Nandprayagwhere the Nandakini joins; Karnaprayagwhere the Pindar joins, Rudraprayagwhere the Mandakini joins; and finally, Devprayagwhere the Bhagirathi joins the Alaknanda to form the Ganges River proper.
After the Tamsa the Gomti River joins, flowing south from the Himalayas. Just before the border with Bangladesh the Ganga project Barrage controls the flow of the Ganges, diverting some of the water into a feeder canal linked to the Hooghly for the purpose of keeping it relatively silt-free.
The Hooghly River is formed by the confluence of the Bhagirathi River and Jalangi River at Nabadwipand Hooghly has a number of tributaries of its own. After entering Bangladeshthe main branch of the Ganges is known as the Padma. The Padma is joined by the Jamuna Riverthe largest distributary of the Brahmaputra.
Further downstream, the Padma joins the Meghna Riverthe second largest distributary of the Brahmaputra, and takes on the Meghna's name as it enters the Meghna Estuary, which empties into the Bay of Bengal. Catchment region of the Ganga The hydrology of the Ganges River is very complicated, especially in the Ganges Delta region.
One result is different ways to determine the river's length, its dischargeand the size of its drainage basin. The river Ganges at Kolkatawith Howrah Bridge in the background Lower Ganges in Lakshmipur, Bangladesh The name Ganges is used for the river between the confluence of the Bhagirathi and Alaknanda rivers, in the Himalayas, and the India-Bangladesh border, near the Farakka Barrage and the first bifurcation of the river.
A significant portion of the discharge from the Ganges comes from the Himalayan mountain system. This section of the Himalaya contains 9 of the 14 highest peaks in the world over 8,m in height, including Mount Everest which is the high point of the Ganges basin.
Frequently, discharge is described for the mouth of the Meghna River, thus combining the Ganges with the Brahmaputra and Meghna. It is one of the key sites for measuring streamflow and discharge on the lower Ganges. Consequently, streamflow in the Ganges is highly seasonal.
The average dry season to monsoon discharge ratio is about 1: This strong seasonal variation underlies many problems of land and water resource development in the region. Bangladesh, in particular, frequently experiences drought during the dry season and regularly suffers extreme floods during the monsoon.
The two largest rivers, the Ganges and Brahmaputraboth split into distributary channels, the largest of which merge with other large rivers before themselves joining.
This current channel pattern was not always the case. Over time the rivers in Ganges Delta have changed coursesometimes altering the network of channels in significant ways. Before the late 12th century the Bhagirathi-Hooghly distributary was the main channel of the Ganges and the Padma was only a minor spill-channel.
The main flow of the river reached the sea not via the modern Hooghly River but rather by the Adi Ganga. Between the 12th and 16th centuries the Bhagirathi-Hooghly and Padma channels were more or less equally significant.
After the 16th century the Padma grew to become the main channel of the Ganges. By the end of the 18th century the Padma had become the main distributary of the Ganges. The present confluence of the Ganges and Meghna formed about years ago.
In there was a great flood on the Teesta Riverwhich at the time was a tributary of the Ganges-Padma River. The flood of caused the Teesta to undergo a sudden change course an avulsionshifting east to join the Brahmaputra and causing the Brahmaputra to shift its course south, cutting a new channel.
This new main channel of the Brahmaputra is called the Jamuna River. It flows south to join the Ganges-Padma. Since ancient times the main flow of the Brahmaputra was more easterly, passing by the city of Mymensingh and joining the Meghna River.Geography, population and climate.
Geography. The Ganges-Brahmaputra-Meghna (GBM) river basin is a transboundary river basin with a total area of just over million km 2, distributed between India (64 percent), China (18 percent), Nepal (9 percent), Bangladesh (7 percent) and Bhutan (3 percent) (Table 1).Nepal is located entirely in the Ganges river basin and Bhutan is located entirely in.
The Ganges (/ ˈ ɡ æ n dʒ iː z / GAN-jeez), or Ganga (Hindustani: [ˈɡəŋɡaː]; Sanskrit: गंगा), is a trans-boundary river of the Indian subcontinent which flows through the nations of India and kaja-net.com 2, km (1, mi) river rises in the western Himalayas in the Indian state of Uttarakhand, and flows south and east through the Gangetic Plain of North India.
Project Management System. The need for revamping the river conservation programme was widely recognised in view of the shortcomings in the approach followed in GAP. World Bank project IN National Ganga River Basin Project N/A.
The Ganga Action Plan has now been shifted to the efforts of Uma Bharti, the Water Resources Minister. Under her jurisdiction, several measures are being implemented to help advance the project. Mar 24, · The Centre would soon start seeking 'donation' from people for the 'Clean Ganga' project for making the river pollution-free, its rejuvenation, conservation and beautification of .
