Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2017 Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2017 The current glaciers in Anatolia have been gradually disappearing with the ongoing climate changes. There are geological proxies left behind from the ice, which is an indication of paleoclimate changes. It is known that the glaciers carry large amounts of sediments in their life cycles. After they retreat, these sediments remain where they were. They are called as moraine, which has been well preserved in some Anatolia mountains. In this study, the paleoglaciers that existed in the Late Quaternary period on the Dedegöl Mountain were reconstructed under the prescribed paleoclimatic conditions. The main idea is to recreate paleoglaciers under different climatic conditions; it is the recreation of the paleoclimate. This approach, in a sense, is aimed at understanding the past-term climate. Thus the proxies left behind by the glaciers have been used as an important proxy to estimate the paleoclimate conditions. Dedegöl Mountain is located within the boundaries of Konya and Isparta provinces. The maximum elevation of the mountain is 2997 m above the sea level. Beys ̧ehir Lake is located about 15 km to the east of the study area. 30 m × 30 m resolution digital elevation model of Dedegöl Mountain was used. The model domain is covering 37.5670 - 37.7237 North latitudes and 31.2100 - 31.3667 East longitudes. The model area is about 16.92 km × 16.92 km = 286 km2. Glacial mass balance was calculated with today's climatic conditions. Then the paleoclimate was modeled. A two-dimensional numerical glacier flow model was written in MATLAB to reconstruct the flow of glaciers under different paleoclimatic conditions. An open source glacier flow model software named Parallel Ice Sheet Model (PISM) was also used. The glacier valleys in the area are identified during two field studies in the summer months of 2015 and 2016. The Sayacak Glacial Valley on the ...
