Formed by accumulated meltwater, the overfilled lakes could suddenly discharge massive volumes of water, known as glacial lake outburst flooding. |
Latvia's undulating landscape is dominated by morainic hills and meltwater deposits dating back to the latest glacial epoch. |
And because many glaciers store large amounts of meltwater and release it suddenly, lives downstream will be lost. |
Following melt initiation, the intensity of melt is another consideration in the production of meltwater runoff. |
Huge glaciers and meltwater carved out the deep trough of the glen some 20,000 years ago. |
Below the glacier lies granite, seamed through with limestone and marble which the constant rush of meltwater has honeycombed with caves. |
