UDC 551.435.4 (084.3)(235.222) THE 1:100 000-SCALE GEOMORPHOLOGICAL MAP OF THE CHUYA INTERMOUNTAIN TROUGH (SOUTHEASTERN ALTAI)
P. Yu. Savelyeva, A. A. Mistryukov
The paper provides results of geomorphological studies of the Chuya intermountain trough relying on field survey data and space images interpretation. Medium-scale geomorphological mapping was based on a Landsat image. Interpretation of the image enabled detailed analysis of the region’s topography, drawing of elementary surface boundaries and revealing of age generations of mesorelief elements. The more detailed topography analysis also involved high-resolution QuickBird images and large-scale air photographs, which allowed outlining of microtopography elements complicating the elementary surfaces (moraines, intermorainal depressions, frost mounds, thermokarst basins, erosion gullies, discharge hollows, and small terrace cusps). The work resulted in a digital geomorphological map at a scale of 1:100 000.
Key words: Mountain Altai, topography, intermountain troughs, geomorphological mapping, remote sensing data interpretation.
