Evaluation of glaciation and glacial shapes using geographic information systems and remote sensing (Eastern Black Sea)

Geçen, Reşat
This study investigates the actual glaciers and the major properties of glacial landscapes (valleys, cirques and lakes) located over the Eastern Black Sea mountain chain using Geographic Information Systems (GIS) and Remote Sensing (RS) technologies. A database is created for each glacial feature that includes fundamental properties of each landscape. Data layers used in the study include digital and analog topographic maps, satellite images, geological maps and drainage maps. The studies carried out yielded identification of 93 glacial valleys (30 main, 63 tributary), 1222 cirques and 685 lakes. Several properties (length, size, aspect, elevation, slope, orientation, roundness, elongation) of each glacial landscape are investigated for the northern and southern parts separately. The frequency of each landscape is found to be more in the northern part of the area. Total area of the actual glacier is found as 0.43 to 0.53 km2 by two methods of remote sensing applications.
