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]
Lower Curtis Glacier is a cirque glacier in the North Cascades in the U.S. state of Washington. Cirque glaciers are glaciers that appear in bowl-shaped valley hollows. [4] [12] Snow easily settles in the topographic structure; it is turned to ice as more snow falls and is subsequently compressed. [12]
A kame delta (or ice-contact delta, morainic delta [1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits. Upon entering a proglacial lake at the end (terminus) of a glacier, the river/stream deposit these sediments. This ...
The water pressure and friction experienced at the base of a glacier depends in part on whether the subglacial hydrological system is channelized or distributed. [5] Channelized systems are an efficient form of drainage as they are able to rapidly move water out of the glacier, reducing water pressure in the system. [5]

The subglacial discharge caused a 15.7 per cent jump in sea-level rise from 0.74 inches (19mm) to 0.86 inches (22mm) by 2300, the researchers found.
Moulins are parts of the internal structure of glaciers, that carry meltwater from the surface down to wherever it may go. [7] Water from a moulin often exits the glacier at base level, sometimes into the sea, and occasionally the lower end of a moulin may be exposed in the face of a glacier or at the edge of a stagnant block of ice.
