| Title: | Numerical simulation of glacial-valley cross-section evolution / Hakime Seddik, Shin Sugiyama, Renji Naruse. |
| Author(s): | Seddik, Hakime. Sugiyama, Shin. Naruse, Renji. |

| In: | Bulletin of Glaciological Research. (2005.), Vol. 22 (2005) |
| Abstract: | Presents numerical model simulating development of U-shaped valleys by coupling model of ice flow model in a transverse section with a subglacial erosion model. Two-dimensional flow field is calculated considering side-wall drag and basal-stress dependent sliding. With glacial erosion modelled as quadratic function of sliding speed, V-shaped profile evolves rapidly into recognizable glacial form with sliding velocities ranging from 3 to 8 m a⁻¹. Investigates influence of lateral shear stress component on U-shaped valley formation. |
