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 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...
متن کاملLate Glacial Origin of the Maumee Valley Terraces, Northwestern Ohio
Four major paired terraces and six short local terraces have been identified along the Maumee River valley between the Ohio-Indiana state line and Perrysburg in northwestern Ohio by detailed field mapping and study of gaging-station records, water-well logs, and soils data. From highest to lowest, the paired terraces have been named the Antwerp, Florida, Napoleon, and Grand Rapids terraces. The...
متن کاملOccurrences of Sinolagomys (Lagomorpha) from the Valley of Lakes (Mongolia)
The genus Sinolagomys is an early representative of the family Ochotonidae, appearing first in the late early Oligocene of Central Asia. It is known in China from Shargaltein Tal, Taben Buluk, Ulan Tatal, and northern Junggaria, and a few specimens from Tatal Gol, Mongolia have been published. For most occurrences, the genus is not represented by many specimens. Extensive studies in the Valley ...
