Water equivalent

Water equivalent of snow cover:
Height of the water layer in mm that forms after the snow cover melts
would occur if the meltwater were to flow without infiltration or evaporation on a horizontal
area would remain. 1 mm water equivalent corresponds to 1 l meltwater / m²
Specific water equivalent:
Water equivalent of a snow cover per cm of snow cover height, expressed in mm / cm
Snow density:
Mass of fallen snow per unit volume in the state of natural
Storage, expressed in g/cm³.
Conversion of snow density and specific water equivalent:
1 g / cm³ = 10 mm / cm
1 mm / cm = 0.1 g / cm³

Specific water equivalent of each type of snow:

The transitions between the individual snow types are not precisely defined!

Fresh snow: freshly fallen snow that has not been on the ground for more than 3 days
Powder snow: dry snow that does not stick together even under pressure
Firn snow: at least 1 year old
