study of glacial valley landform case study: sahand glacial valleys
abstract a mountain glacier, when it occupies a river valley, immediately begins to change the cross-section and profile of that valley. river valleys in mountain areas tends to have v-shaped profiles. glaciers work to widen as well as deepen their valleys and the typical cross-section of a glacial valley is u-shaped. the u-shaped glacial valley is one of the most characteristic of glacial land...
متن کاملFeatures of glacial valley profiles simply explained
[1] Glacial occupation of alpine valleys results in a distinct signature in the long-valley profile, including steepening of the profile in the headwaters, flattening at lower elevations, and a step in the profile at the convergence of headwater tributaries. We present analytic results for glacial erosion patterns by making the following assumptions: (1) the initial profile is linear, (2) the w...

متن کاملGlacial Flow Modeling of the Martian North Polar Layered Deposits
Introduction: Recent observations of the Martian North Polar Layered Deposits (NPLD) suggest that glacial flow may govern its large-scale evolution [1]. There are two basic glaciological questions of climatological importance: (1) How fast is the NPLD presently flowing? (2) And does the NPLD experience " ice ages " : i.e., episodes of glacial advance and retreat at other orbital epochs? To addr...
متن کاملNumerical simulation of the evolution of glacial valley cross sections
A numerical model was developed for simulating the formation of U-shaped glacial valleys by coupling a two-dimensional ice flow model with an erosion model for a transverse cross section. The erosion model assumes that the erosion rate varies quadratically with sliding speed. We compare the two-dimensional model with a simple shallow-ice approximation model and show the differences in the evolu...
