A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. 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. The melting of ice forms different types of glacial streams such as supraglacial, englacial, subglacial and proglacial streams. 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. The water accumulates on top of the glacier in supraglacial lakes and into supraglacial stream channels. The meltwater then flows through various different streams either entering inside the glacier into engl

  • A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. 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. The melting of ice forms different types of glacial streams such as supraglacial, englacial, subglacial and proglacial streams. 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. The water accumulates on top of the glacier in supraglacial lakes and into supraglacial stream channels. The meltwater then flows through various different streams either entering inside the glacier into englacial channels or under the glacier into subglacial channels. Finally, the water leaves the glacier through proglacial streams or lakes. Proglacial streams do not only act as the terminus point but can also receive meltwater. Glacial streams can play a significant role in energy exchange and in the transport of meltwater and sediment. (en)
  • Un bédière (un galicismo empleado en glaciología) es un torrente que atraviesa la superficie de un glaciar y que es alimentado por el agua de deshielo y/o la lluvia. Los bédières pueden dar lugar a arroyos de montaña cuando llegan al frente glaciar o puede precipitarse en un molino glaciar y alcanzar en el interior del glaciar. El flujo de los bédières es muy variable, y van desde un simple chorrito de agua hasta arroyos del tamaño de un verdadero río. Se encuentran en todos los tipos de glaciares, pero los más grandes se dan en los inlandsis y los campos de hielo. El término proviene del latín bediara, que deriva asimismo de la palabra gala bedo, que significa «canal». (es)
  • Une bédière est un torrent parcourant la surface d'un glacier et alimenté par les eaux de fonte et/ou de pluie. Les bédières peuvent donner naissance à des torrents de montagne lorsqu'elles arrivent au front glaciaire ou bien peuvent s'engouffrer dans un moulin et rejoindre l'intérieur du glacier. Le débit d'une bédière peut être très variable, pouvant aller du simple filet d'eau à celui d'une véritable rivière. On les rencontre sur tous les types de glaciers mais les plus grandes se trouvent sur les inlandsis et les calottes glaciaires. Le terme provient du latin bediara dérivant lui-même du mot gaulois bedo signifiant « canal ». (fr)
  • Il torrente epiglaciale, conosciuto anche come bédière, è un corso d'acqua che si forma sulla superficie del ghiacciaio, alimentato dalla fusione dello stesso o dalle precipitazioni. (it)
