Hydrogeological aproaches as the tool for the mitigation of negative impact of climate change in water management: Evaluation of qualitative and quantitative aspects of managed aquifer recharge
Rozman, David ; Hrkal, Zbyněk (advisor) ; Rapantová, Naďa (referee) ; Pech, Pavel (referee)
The thesis adresses the issue of efficient use of groundwater resources under the ongoing climate change conditions, which results in reduced natural recharge of aquifers. It focuses on the assessment of qualitative and quantitative aspects of managed groundwater recharge. In addition to a review of the issues of artificial recharge, the thesis provides two outputs. The first one is a critical evaluation of the effectiveness of artificial infiltration in crystalline conditions, typical for a large part of the Czech Republic, where at present artificial infiltration is not a commonly applied procedure. The second key output is the monitoring of the occurrence of new types of micropollutants from the category of so-called emerging pollutants, which may limit the availability of drinking water sources, especially in periods of climatic stress. Research within the PhD project was conducted at several pilot sites and the results are published in peer-reviewed articles. The obtained findings confirm the suitability of the managed groundwater recharge procedure and the considerable effectiveness of attenuation processes of the aquifers in degrading micropollutant pollution.

Surface and ground water of the Libický floodplain forest
Bašta Spinali, Izabela ; Weiss, Tomáš (advisor) ; Slavík, Martin (referee)
In the Quaternary, the area of the Libický floodplain forest was shaped mostly by the action of the Elbe river. The river generated a structure of oxbow lakes, pools, wetlands, floodplain forests or wet grasslands. These are connected by shallow groundwater of the Quaternary aquifer. During the Upper Cretaceous period, the area of Libický forest was flooded by the sea, which resulted in the formation of the bedrock of Libický forest - now the Cenomanian aquifer of the Poděbrady mineral spring structure. This aquifer is part of the Bohemian Cretaceous Basin. This thesis provides an overview about the waters in the area of the Libický forest, especially about: the development of the structures of surface water during the last ~2k years, groundwater of the quaternary aquifer and mineral water of the Poděbrady mineral spring structure. Finally, this thesis contextualizes this knowledge into climatic, geological, pedologic and also to ecological conditions of the area of Libický luh which is an important ecosystem in terms of biodiversity in otherwise relatively densely populated agricultural landscape. Key words: Libický luh, surface water, hydrology, Elbe, groundwater, hydrogeology, Cenomanian aquifer, Bohemian Cretaceous Basin, Poděbrady mineral spring structure, floodplain forest

Pharmaceuticals issues in groundwaters
Šrot, Martin ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
Main objective of the diploma thesis was to observe the concentrations of selected types of drugs in the environment around the area of the village Horní Beřkovice. This goal was achieved by monitoring of the drugs concentration in surface and ground waters at Horní Beřkovice site. Monitoring system allowed to detect the passage of pollution from the source of the contamination, through sewage treatment plant, the unsaturated zone and aquifer to a potential user of contaminated groundwater. The diploma thesis is based on the field data from TACR project. I have analyzed data from the six samplings at the area of the village Horní Beřkovice with regard to the observed drugs or their residues in surface and ground waters. I have compared the results with data from the sewage treatment plants in the river basin of Želivka. Keywords: ground water, surface water, sewage treatment plant, drugs, contamination

Hydrology of Amateur cave and sinking streams focused on tracer tests
Gregorová, Anita ; Bruthans, Jiří (advisor) ; Vojtěchová, Anna (referee)
This study briefly summarizes methodology of tracer studies in karst areas (the way how they were carried out and their evaluation). Second part of the study specifies geological, hydrogeological and hydrological situation of the area of interest - northern part of the Moravian Karst, surroundings of Sloup - using available literature on that topic. Description of the area was completed with field measurements done by the author. Their results can be used as a basis for possible future surveys.

Aral Sea
Chupík, Jan ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
In the introducion of this seminar paper author deals with former natural conditions of Aral lake. It focuses on climatic conditions, morphology, hydrology and local land use situation.Because the region of Central Asia has been historically wedged between the three empires, it is also appropriate to describe closer the historical and political development of the region. The focus of the thesis is to analyze the causes of hydrological changes, when the desertification of Aral Lake has a catastrophic impact on the ecosystem and human society in the region. The return of Aral Lake to the situation sixty years ago is, unfortunately, unrealistic, but various remedial measures are being implemented to improve the situation as much as possible. The goal is to make the most of the situation. This is also done through various international projects. Therefore, the vision of the future development of the region around Aral Lake is outlined. There are also similar cases in the world, most notably the Dead Sea. The work concluded that at least some hope for recovery unfortunately only has the northern part of Aral's lake, while the southern part is probably lost forever.
