Luggye (Lugge) Glacial Lake: Gasa District: Lunana Gewog: Luggye first appeared in 1967 atop its glacier. It has a depth of 142 metres (466 ft), and a width of 30 metres (98 ft). Luggye produced a significant GLOF in 1994. [9] [21] [22] [23] Bechung Glacial Lake: Gasa District: Lunana Gewog: Supra-glacial lake. [9] [21] Roduphu Glacial Lake ...
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup .
These gewogs are the site of some of the most notable and precarious glaciers of Bhutan. These glaciers have thawed significantly over the course of recorded history, causing lethal and destructive glacial lake outburst floods. Chief among the glaciers and glacial lakes within the park are Thorthormi, [5] [6] Luggye, [7] and Teri Kang. [8]
Heavy rains and a glacial lake outburst flood combined in 2013 in India to kill thousands of people. A 2021 deadly flood in India that was initially attributed to a glacial lake outburst wasn’t ...
On 7 October 1994, a GLOF from Luggye lake (part of Lunana glacial system) led to over 20 fatalities in Punakha. [1] This disaster, the first of its kind in Modern Bhutan, increased the frequency of glacial-system-surveys by manifold. [1] Evaluation of GLOF hazard has since formed a significant component of glacial expeditions. [1]
Tangible climate change has resulted in the warming and recession of many of Bhutan's glaciers, increasing the frequency and severity of glacial lake outburst floods (GLOFs). Bhutan has also seen a shift in agriculture patterns due to climate change, prompting concern over the stability of agriculture in Bhutan.
Flash floods resulting from glacial lake outburst flooding in the upper reaches of the valley, are a common occurrence in the Mo Chu and Pho Chu rivers, and in the past caused flooding and damage to the dzong, especially in 1957, 1960 and 1994. Fires and earthquakes have also further added to the problem.
Glacial lakes have been rapidly forming on the surface of the debris-covered glaciers in this region during the last few decades. USGS researchers have found a strong correlation between increasing temperatures and glacial retreat in this region. Glacial motion is the motion of glaciers, which can be likened to rivers of ice. It has played an ...
