During the outburst flood of a glacier-dammed lake on Gornergletscher, Switzerland, in July , the drained lake water triggered anomalous glacier motion. Glacial-lake floods occur when the dams forming the glacial lakes fail and release the water producing a surge of water downstream (ICIMOD, ). For this reason, they have similar effects as the dam-break floods discussed in Section The dams may form either due to the blockage of ice at the outflow of the glacier, similar to ice jams. A jökulhlaup is an Icelandic word for a glacier outburst flood that has been adopted by the English language and is now used to describe any large and abrupt release of water from a subglacial or proglacial lake/reservoir. It was triggered by the sudden release of about X m3 of water from moraine-dammed Klattasine Lake. The escaping waters breached the moraine, mobilized large quantities of sediment in the valley below the lake, and generated a debris flow, with an estimated volume of 2 4 X m3, that travelled in one or more surges 8 km to the mouth of Cited by:

The upper glacier was a smooth expanse of snow. By the lake was evident, and was 75 meters long. In the lake had expanded to a length of meters. By the lake was m in length, and had some thin icebergs broken off from the glacier front.

Annals of Glaciol InternationalAssociation of Hydrological Sciences Red Book Publication Monitoring glacier mass balance can provide a seasonal measure of water accumulation, storage, and loss, which is useful for extrapolation to the greater population of glaciers in the region (Riedel and Burrows, ). Level One: Equilibrium Line Altitude and Accumulation-Area Ratio. The water cycle of a basin is affected by regional climate, topography, and human activities [1,2,3,4].Global warming has accelerated the regional water cycle and has changed the rainfall–runoff process in mountainous areas, resulting in changes in runoff recharge from glacier meltwater and precipitation .For extremely arid areas with sparse precipitation, meltwater is the main recharging Author: Xiaofei Ma, Wei Yan, Chengyi Zhao, Zbigniew W.
