An Ice Dam is one of the possible results of a glacier melting.
If you have seen the animated movie "Ice Age 2" you will understand the concept.
As the glacier melts, it forms a pool (and eventually a lake) of melt water held in by the leading edge of the glacier (which forms an ice dam).
Eventually the leading edge melts, and releases the lake in the form of a rapid flood.
Most of the Flood legends are based on the collapse of ice dams.
The legends from the Mediterranean have a different cause. During the ice age the sea level fell so that the straits of Gibralter and other bottle necks were above sea level.
When the glaciers melted, the sea level rose and flooded over these bottle necks, flooding the lowland areas behind the bottlenecks.
Do they not teach this in high school science classes where you live?
