Body of liquid water that flows down a channel formed by a glacier
Image shows the different stream types that are found on a glacier. The different streams are supraglacial, subglacial, englacial and proglacial.
A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows.[1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice.[1] The melting of ice forms different types of glacial streams such as supraglacial, englacial, subglacial and proglacial streams.[1] Water enters supraglacial streams that sit at the top of the glacier via filtering through snow in the accumulation zone and forming slush pools at the FIRN zone.[2] The water accumulates on top of the glacier in supraglacial lakes and into supraglacial stream channels.[2] The meltwater then flows through various different streams either entering inside the glacier into englacial channels or under the glacier into subglacial channels.[2] Finally, the water leaves the glacier through proglacial streams or lakes.[2] Proglacial streams do not only act as the terminus point but can also receive meltwater.[2] Glacial streams can play a significant role in energy exchange and in the transport of meltwater and sediment.
