Fluctuations in the groundwater level in the montane peat bog Rokytka
Lencová, Kateřina ; Šobr, Miroslav (advisor) ; Doležal, Tomáš (referee)
Peatbogs are globally widespread ecosystems that have a major influence on the hydrological conditions of watersheds. Of particular importance are mountain highlands, which are characterized by their occurrence in the source areas of streams. Despite the indisputable importance of the montane peatbogs in terms of runoff conditions, their influence has not yet been conclusively clarified. Montane peatbogs are a particularly important topic for the Šumava region, where they represent a fundamental element of the landscape. The study site is therefore situated in one of the Šumava's spring areas - the Rokytka watershed. As part of this thesis, the issue of the hydrological function of the monitored peatbog has been viewed mainly through the differences in the fluctuation of the groundwater level in different parts of the peatbog. At the same time, the influence of the precipitation on the change in the groundwater level in the peatbogs and on the runoff response of the Rokytka brook has been monitored. Precipitation is the only source of water for the highlands and its influence is therefore crucial. Although several previous studies have focused on the influence of this highland on the runoff conditions of the Rokytka brook, groundwater levels from manually measured probes have not yet been analysed....

Influence of rock glaciers on hydrological regime
Lencová, Kateřina ; Šobr, Miroslav (advisor) ; Falátková, Kristýna (referee)
Within this work, a literary research was performed on the topic of rock glaciers and their influence on river runoff. Rock glacier are features typical for high-mountain periglacial environment. Through the accumulation of part of the flowing glacial water, they significantly affect the timing and quantity of watershed discharge. In addition, stone glaciers preserve significant volumes of water in the form of buried ice, the gradual melting of which regulates river runoff, especially in the dry seasons. A physical- geographical characteristics of the Ala Archa river basin was performed and supplemented by a more detailed climatological characteristic of the study area based on the own processing of meteorological data from the Adygine meteorological station. The purpose of this work was to assess the impact of rock glaciers in the basin of eight selected rivers, which drain the Kyrgyz and Kungej Alatau, on their hydrological regime. It was found that the presence of rock glaciers in the monitored basins affects the runoff regime of these rivers, especially by reducing the differences between their June and July runoffs. Key words: rock glacier, hydrological regime, Tien Shan
