Glacial hydrological regime, case study of lake Adygene (Tien - Shan, Kyrgyzstan)
Beitlerová, Hana ; Šobr, Miroslav (advisor) ; Kocum, Jan (referee)
This thesis is concerned with detailed analysis of glacial hydrological regime and its influencing factors. Knowledges published in the domestic and foreign scientific literature were applied on data acquired in the area of Adygine Lake (Tien - Shan, Kyrgyzstan). The lake is a part of a lake system recently developed in the surroundings of a retreating glacier. There is a potential risk of dam failure in terms of its stability. Lake level fluctuations depending upon climatic conditions, melt water inflow and capacity of subsurface outflow channels were observed. Key words: glacial regime, glacial lake, melt water, glacier melt, diurnal variations, seasonal variations, delay of runoff

Application of degree-day accumulation and snowmelt model in the Ptačí Brook basin
Beitlerová, Hana ; Jeníček, Michal (advisor) ; Pavlásek, Jiří (referee)
Snow accumulation and snowmelt research is one of the most important hydrological issues in mountain areas World-wide. Spring snowmelt, usually in the combination with intensive rainfall or high air temperature, is one of the most common causes of flooding in the Czech Republic. Mathematical modeling of hydrological processes belongs to effective instruments of flood protection and finds its use in a variety of areas. For example, water management, hydrological forecasts for agriculture, information for dam regulation or for recreational areas and water sports are all affected. This thesis focuses on snow accumulation and snowmelt modeling with use of the empirical Degree-day method. This method is based on the relationship between snowmelt rate and air temperature. The American HAC-HMS programme is used for the simulation of hydrological processes. The main goal of this thesis is to calibrate the model and to simulate snow accumulation, snowmelt and run-off from the watershed. The experimental basin 'Ptačí potok' is situated in the central part of the Šumava Mountains, in altitude of about 1,200 m. Two winter seasons, 2011 and 2012, were simulated. Simulations showed high reliability and correct calibration of the Temperature index snowmelt model. Simulations of the snow water equivalent evolution...
