Abstract
One of the most important climatic parts of the heritage of the fourth era in the highlands of Iran is the glacial geomorphology and the effects of the glaciers of that period. The Damavand glaciers, with more than 15 small and large tabs with signs of life and activity, are the only survivors of those glaciers. Scattered studies have been conducted on these glaciers in recent centuries by Iranian and foreign scholars. However, a comprehensive report that describe and characterize the geomorphologic and morphodynamic characteristics of the glaciers in this region has not yet been compiled.
In this paper, we try to interpret and analyze the shapes of glacier morphology, and to determine the extent and expansion of glaciers using remote sensing technology.
The method of research is based on the fieldwork and the use of satellite imagery. The results show that the Damavand ice glacier is undergoing gradual shrinkage and melting under the influence of increasing temperature of the present age, and the existing ice cores are the remains of past glacial periods. The insignificant nutrition of glaciers through avalanches is not enough, but the effects and evidences of life are still evident.
