Classification of glacial lakes and methods of inventory
Pisarčíková, Alexandra ; Vilímek, Vít (advisor) ; Šobr, Miroslav (referee)
Classification of glacial lakes and methods of inventory Abstract: Classification of glacial lakes has its application all around the world. However, there is no unified system of typology that would make it possible to simplify and increase the effectivity of labour inventory. The thesis is dedicated to creation an overview of the definitions of glacial lake divided by euro-atlantic and asian literature and its resulting evaluation. The inventory of glacial lakes is closely connected to their classification. Therefore, the work subsequently presents individual methods that lead to the creation of a lake inventory. The basis of the creation of a design of the classification system is the research from already created glacial lakes classifications and analysis by which typology can be created. Overall, the classification of the lakes is divided into two main groups: by position to glacier or relief and according to the type of dam. Furthermore, 280 glacial lakes were analysed based on the inventory table in an interest area. On the basis of a created classification design, most of the lakes were classified under the inventory, thereby confirming its used application. Keywords: glacial lake, typology, classification, inventory, RS

Glacial Outburst Lakes in Kyrgyzstan (case study: Glacier Complex Adygine)
Falátková, Kristýna
In the context of changing climate retreat of mountain glaciers occurs at many places on the planet. One of the consequences is emergence or increase of the outburst risk at lakes situated in front of the glacier terminus. Flood caused by the glacial lake outburst often appear suddenly and can threaten settlements in lower parts of a valley. In the Kyrgyz mountains of Tien Shan there are about 350 lakes at risk of outburst, long-term monitored and dangerous locations are presented in this work. The highest attention is paid to Adygine area where several lakes of different genetic type and age can be found. The largest lake of the locality, the Upper Adygine lake, is subjected to more detailed survey aiming to asses its hydrological regime and to confirm or disprove speculation about outburst possibility of this lake. Keywords: glacial lake, hydrological regime, glacier retreat, Tien Shan, Kyrgyzstan

Dynamics of glacial lakes and hydrological conditions of a glacial-morainic complex (Adygine, northern Tien Shan)
Falátková, Kristýna ; Janský, Bohumír (advisor) ; Petrakov, Dmitry (referee) ; Pánek, Tomáš (referee)
The thesis deals with hydrological conditions in a proglacial environment, focusing on the development of glacial lakes and the assessment of their susceptibility to outburst. The study site is the Adygine glacier-moraine complex located in the north-facing valley of the Kyrgyz Ridge, northern Tien Shan, Kyrgyzstan, at an altitude of 3400-4200 m a.s.l. In the past 50 years, the receding glacier allowed formation of several lakes, which form a three-level cascade and are fed by glacier meltwater. Below the glacier, there is a complex of several generations of moraines, through which the glacier meltwater is routed downstream. The aims of the work were to evaluate the development of individual lakes, their susceptibility to sudden outburst and possible triggers, to estimate the probable development of the site in the future, to analyse the hydrological regime of the lakes and to obtain basic information on the subsurface flow of water from the site to the stream. For the purposes of assessing the development of the lakes, the data obtained in the field (geodetic surveying of a shore line, bathymetric measurements), as well as satellite and aerial images were used. Fluctuation of lake water level was monitored by pressure sensors and the processing of this data allowed to analyse the hydrological...
