Gangotri Glacier

• Gangotri Glacier is situated in the Uttarkashi District of Uttarakhand.
• The Gangotri glacier originates at the northern slope of Chaukhamba range of peaks in Garhwal Himalayas. It is about 30 km long and 0.5 to 2.5 km wide.
• Gangotri is not a single valley glacier, but a combination of several other glaciers. This glacier comprises three main tributaries, namely Raktavaran (15.90 km), Chaturangi (22.45 km) and Kirti (11.05 km) and more than 18 other tributary glaciers.
• The Bhagirathi, one of the main tributaries of the Ganga, originates from the gangotri glacier. The Ganges has five headstreams the Bhagirathi, the Alaknanda, the Mandakini, the Dhauliganga, and the Pindar all rise in the mountainous region of northern Uttarakhand.

Peacock

• The collective name for peacocks is peafowl. The male of the variety is called a peacock and the female peafowl is called a peahen.
  • The Indian peacock is also the National Bird of India.
  • Peafowl (Pavo cristatus) belongs to the Phasianidae family. They are among the largest of all birds that fly.
    • Phasianidae is the pheasant family, a bird family that includes among its members the jungle fowl (from which the domestic chicken is descended), partridge, peacock, pheasant, and quail.
  • The two most-recognizable species of peafowl are:
    • The blue Peacock/ Indian Peacock found in India and Sri Lanka.
    • The green or Javanese peacock (P. muticus) found in Myanmar (Burma) to Java.
• Habitat:
  • The Indian peafowl is a native of India and some parts of Pakistan and Sri Lanka.
  • The species are currently habituated more in central Kerala, followed by southeast and northwest parts of the state.
    • At least 19% of the states’ area is suitable habitat for this species and this may increase by 40-50% by 2050.
  • They are well adapted to living in forest edges and cultivated areas.

• The river runs for approximately 81 kilometers between the Rudraprayag and Sonprayag areas and emerges from the Chorabari Glacier.
• The Mandakini merges with river Songanga at Sonprayag and flows past the Madhyamaheshwar temple at Ukhimath.
• At the end of its course it drains into the Alaknanda, which flows into the Ganges.

Glacial Lake Outburst Flood (GLOF)

• About:
  • A glacial lake outburst flood (GLOF) is a type of catastrophic flood that occurs when the dam containing a glacial lake fails, releasing a large volume of water.
  • This type of flood is typically caused by rapid melting of glaciers or the buildup of water in the lake due to heavy precipitation or the inflow of meltwater.
    • In February 2021, Chamoli district in Uttarakhand witnessed flash floods which are suspected to have been caused by GLOFs.
• Causes:
  • These floods can be triggered by a number of factors, including changes in the volume of the glacier, changes in the water level of the lake, and earthquakes.
  • According to NDMA (National Disaster Management Authority), glacial retreat due to climate change occurring in most parts of the Hindu Kush Himalayas has given rise to the formation of numerous new glacial lakes, which are the major cause of GLOFs
