A set of snow removal parameters can be assigned to the Plowable area.
These parameters consist of the depth at which snow removal begins, and the fractions of snow moved onto various other areas.
For each of the three categories of subcatchment surface type you may specify the following.

Description |
|
Snow Pack Name |
User-assigned snow pack name. |
|
Snow Pack Selector |
Select the snow pack to edit |
|
Add |
Click to add a new snow pack to the project. |
|
Delete |
Click to delete a snow pack from the project. |
|
Depth at which snow removal begins (in or mm) |
No removal occurs at depths below this, and the fractions specified below are applied to the snow depths in excess of this number. |
|
Fraction transferred out of the watershed |
The fraction of excess snow depth that is removed from the system and does not become runoff. |
|
Fraction transferred to the impervious area |
The fraction of excess snow depth that is added to snow accumulation on the pack's impervious area. |
|
Fraction transferred to the pervious area |
The fraction of excess snow depth that is added to snow accumulation on the pack's pervious area. |
|
Fraction converted to immediate melt |
The fraction of excess snow depth that becomes liquid water, which runs onto any subcatchment associated with the snow pack. |
|
Fraction moved to another subcatchment |
The fraction of excess snow depth which is added to the snow accumulation on some other subcatchment. |
|
Name |
The name of the subcatchment. |
You can also specify what portion of the impervious area is not subject to areal depletion.
