| - | Glaciers are divided into four types. The default type is (a small) glacier, the alternatives are ice cap (large glacier), ice sheet and infinite glacier. Glacier type is given as input, or determined by the glacier area (a threshold (//glac2arlim//, a general parameter). The glacier area is used to determine the glacier type if it is not given as input and the threshold parameter is set. The glaciers will then be divided into (small) glaciers and ice caps. | + | Glaciers are divided into four types.

| - | The default glacier type is (a small) glacier, while the ice cap represent larger glaciers. The difference between the two are in the parameter values for the volume-area relationship. The default values for the volume-area relationship are based on Radic and Hock (2010). | + | The default glacier and the ice cap glacier type differ by having different parameter values for the volume-area relationship. The default values for the volume-area relationship are based on Radic and Hock (2010). |
| The ice sheet glacier do not simulate an snow field, and the glacier will have a constant area. The ice sheet glacier type is thus not depending on the volume-area relationship, except for initial volume if that is not given. In that case the initial volume of the ice sheet glacier will used the ice cap parameter values. | The ice sheet glacier do not simulate an snow field, and the glacier will have a constant area.
