ABSTRACT

After the regression of mountain glaciers, the typical forms of morainic lake basins were created in morainic deposits at the bottoms of the Tatras valleys. During some period they were filled by alpine lakes. During Holocene, a lot of lake basins were deformed by geomorphological processes. Frequently the lakes in them disappeared. Nowadays, it is possible to identify them by precise DTM of relief despite long time interval. In this article, we reconstruct defunct alpine lake in Zelené pleso valley, its hypothetical lake basin morphology, volume, area and altitude of the water. The reconstruction will be made by basic identification of a dry lake basin and analysis of a precise DTM. We simulate typical palaeo form of the relief. On the basis of the actual and simulated DTM we also bring the information about the volume of sediments that were taken away by erosive processes from the morainic dam of former lake during Holocene.

Key words: Dry lake basin. Lake. Morainic dam. Reconstruction. High Tatra
