Field	Description
Depth at which snow removal begins (in or mm)	Depth which must be reached before any snow removal begins.
Fraction transferred out of the watershed	The fraction of snow depth that is removed from the system (and does not become runoff).
Fraction transferred to the impervious area	The fraction of snow depth that is added to snow accumulation on the pack's impervious area.
Fraction transferred to the pervious area	The fraction of snow depth that is added to snow accumulation on the pack's pervious area.
Fraction converted to immediate melt	The fraction of snow depth that becomes liquid water which runs onto any subcatchment associated with the snow pack.
Fraction moved to another subcatchment	The fraction of snow depth which is added to the snow accumulation on some other subcatchment. The name of the subcatchment must also be provided.

Note: The various removal fractions must add up to 1.0 or less. If less than 1.0, then some remaining fraction of snow depth will be left on the surface after all of the redistribution options are satisfied.
