what direction does the water flow from glacier melting
Slope and temperature play a very important role here, the steeper  the slope and the higher the temperature, the easier the glacies  flows. That being said, a glacier typicâ¦ally starts to flow when it  reaches a thickness of between say 50 and 200 meters, depending on  slope and temperature. The speed at which it flows is then several  meters per year to several tens of meters per year, again depending  on slope and temperature.
