If more snow and ice are added than are lost through melting, calving, or evaporation, glaciers will advance. Oceanic evaporation contributes to the net fresh water input. Evaporation rates in the fall and early winter help determine the extent of winter ice cover.

Glacier advance and retreat glaciers advance and retreat. Ice begins to flow like a conveyor belt, driven by gravity and ever. The accumulation (input) zone is where a glacier gains snow and ice through snowfall and compression.

The flow is produced by rainfall from. Dead sea and salt evaporation pondsthe data from the two instruments aboard the four satellites are processed through a set of algorithms to make the imagery consistent. Runoff is the measurement of the flow of water into a lake, stream or other waterbody, usually expressed in cubic feet per second. Evapotranspiration (et) is the sum of water evaporation from the land surface and its transpiration, or movement, through vegetation.
A large amount of heat loss from the lakes is required to cool the water enough to. Et measurements are useful in monitoring.
