Meltwater

Others have artificial reservoirs that collect water from rivers, which receive large influxes of meltwater from their higher elevation tributaries.

[4] Cities that indirectly source water from meltwater include Melbourne, Canberra, Los Angeles, Las Vegas among others.

[5] Agriculture in Wyoming and Alberta relies on water sources made more stable during the growing season by glacial meltwater.

[6] Cities that rely heavily on glacial meltwater include La Paz and El Alto in Bolivia, about 30%.

The fine powder is then suspended in the water and absorbs and scatters varying colors of sunlight,[8] giving a milky turquoise appearance.

GPS measurements of ice flow have revealed that glacial movement is greatest in summer when the meltwater levels are highest.

In a report published in June 2007, the United Nations Environment Programme estimated that global warming could lead to 40% of the world population being affected by the loss of glaciers, snow and the associated meltwater in Asia.

[13] The snow of glaciers in the central Andes melted rapidly due to a heatwave,[14] increasing the proportion of darker-coloured mountains.
