MARC recordComputational ice-divide analysis of a cold plane ice sheet under steady conditions / Ferenc Szidarovszky, Kolumban Hutter, S. Yakowitz.
| Title: | Computational ice-divide analysis of a cold plane ice sheet under steady conditions / Ferenc Szidarovszky, Kolumban Hutter, S. Yakowitz. |
| Author(s): | Szidarovszky, Ferenc. Hutter, Kolumban. Yakowitz, S. |

| In: | Annals of Glaciology. (1989.), Vol. 12 (1989) |
| Abstract: | Dimensionless form of field equations and boundary conditions governing plane flow of grounded cold ice sheet emerge from balance statements of mass, momentum, and energy. They constitute amended version of reduced model of ice-sheet flow, due to Morland (1984) and Hutter (1983), and circumvent restrictions imposed by reduced model, namely, neglect of longitudinal stretching effects. Amended version permits satisfaction of mass balance at ice divide for arbitrary basal sliding conditions and gives better reproduction of local flow features. Under very mild simplifying assumptions that horizontal thermal conditions can be ignored close to divide, numerical analysis of ice divide is presented which has second-order accuracy. Analysis permits determination of temperature profile, velocity, and stress distributions in symmetric ice divide, provided that ice-divide height, local behaviour of accumulation and surface-temperature function, and geothermal heat flow are prescribed. |
