Morphometric Properties of Glacial Cirques in Zagros Mountain, IRAN
The morphometry of 187 cirques like forms is performed in the selected regions of Zagros Mountain with the use of GIS. The cirques like forms were delimitated manually and their headwall and floor boundaries were modified based on the classified slope map. The power law functions were fitted to 187 longitudinal cross-sections of the cirque like forms and their parameters were analyzed. All the ...
متن کاملDeveloping a Semantic Model of Glacial Landforms for Object- Based Terrain Classification – the Example of Glacial Cirques
Earth surface processes operate on various spatio-temporal scales and produce landforms that are structured in a nested hierarchical manner. Semi-automated extraction of selected landform types from digital elevation models (DEMs) is of great importance in geomorphology. Object-based image analysis (OBIA) provides an attractive framework for multi-scale terrain segmentation and classification. ...
متن کاملScale-Specific Landforms and Aspects of the Land Surface
The land surfaces of Earth, of other planets and of moons show both scalespecific and scaling behaviour. Size and spacing of landforms often show clustering around characteristic scales or between limits related to process thresholds or to the space available. This is clearest for various bedforms, in dynamic equilibrium with the last dominant flow or several flows. It is also clear for glacial...
متن کاملComparison of Glacial Relief Landforms and the Factors Which Determine Glaciation in the Surroundings of Černé Jezero Lake and Čertovo Jezero Lake
Conditions for the Pleistocene glaciation in the regions of Černé Jezero and Čertovo Jezero lakes in the Šumava Mts. are analyzed in this paper, with a comparison of the resulting glacial landforms. Although the two cirques are immediate neighbours, have approximately the same area, altitude and relative vertical relief-dissection, their glacial erosion and accumulation relief segments exhibit ...
متن کاملgeomorphological and sedimentological evidence of alpine glaciers in the zagros mountains, dinevar, iran
the altitude to which the past glaciers had been extended during the last glacial period in dinevar basin, western iran, can be estimated based on glacier-geomorpic evidence such as cirques, u-shaped valleys, and the moraines in lowlands. this study estimates the elevation of snowline during this period for the basin as the objective of the research. topographic and geologic maps, landsat image...
