The headwaters of The Enguri Riverare located on the southern slope of the Greater Caucasus, in Georgia. Detailed morphologic and morphometric description of glaciers is given. During our research, we used the topographic maps of 1960 and Landsat L5 TM (Thematic Mapper) aerial images, taken in August 1986 and 2014, and the GPS data of 2014. In the mentioned study, except for the old topographic maps and aerial images we used the climate information that we have collected from Mestia weather station (Mestia is the regional center of Zemo Svaneti), which is the only operating weather station in region. Along with the dynamics of glaciers the course of the air temperature has been identified, mainly trends of mean annual and monthly air temperatures for different periods 1961-2013, 1961-1986, 1987-2013 are made. According to them, main reasons for glacier retreat areanalyzed.展开更多
