The issue of drugs in surface and ground waters
Šrot, Martin ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
The presented work deals with the state of research of medicinal substances in water formations of Czech Republic and in smaller ammount it deals with this issue abroad. It provides an overview of the most frequently occurring medicinal substances and methods for their detection and also describes the possible sources of pollution and impact of these substances on the environment. Keywords: ground water, surface water, drugs, contamination

Flooding of the Hamr I mine and evaluation of the geological structure impact on the hydrogeological conditions in the northeastern part of Stráž block
Rozman, David ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
The main objective of diploma thesis is to evaluate the impact of the geological structure on the hydrogeological conditions in the northeastern part of Stráž block. The study area in northern Bohemia is characterised by Cenomanian and Turonian sandstone aquifers, which are horizontally divided by Lower Turonian aquitard. The thesis focuses groundwater level analysis and study hydrogeological impacts of faults, neovolcanic veins and disturbances of rock environment caused by uranium mining. First part of the study presents description of general geological and hydrogeological conditions in the area with summary of previous investigations and reports. Various hydraulic interventions during mining, which have great impact on the groundwater level situation are described. Based on the data from collected boreholes, contour maps of groundwater level are prepared to study its shape and temporal changes. Hydraulic communication through aquitard and through Stráž fault zone have been examined by correlations of groundwater levels. The results of the study confirm sealing effect of Stráž fault zone in the examined section. Barrier effect of the neovolcanic veins has been confirmed on several locations and examples of increased hydraulic conductivity as the result of fault disturbances have been located....

Interaction of surface water and groundwater og Luznice River
Slabá, Zdenka ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
This thesis is a part of a project run by The Department of Geography, Faculty of Science in Charles University in Prague. This project deals with processes in floodplains of the Lužnice, the Stropnice and the Blanice rivers. The research in the floodplain of the Lužnice started in the year 2008 and is focused on the interaction between groundwater and surface water. The monitored territory it is situated to the south of a locality called Halámky and its area is 0,6 km2. In this thesis mainly the outputs of the research were elaborated. The highlighted points were the interpretation of the groundwater level behaviour, the groundwater streaming orientation in the area and interaction between groundwater and surface water. The outputs of this thesis can be used in the next stages of the project.

Mineral waters of Františkovy Spa region
Veselá, Michaela ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
The thesis deal with mineral water of Františkovy Spa region and NPR SOOS. Its aim is to provide information about the history of the explotation of mineral water in Františkovy Spa and its surroundings, in the locality of SOOS. It is divided into several chapters. The first chapter introduce Františkovy Spa and its geological and hydrogeological conditions. The history of exploitation of mineral water is also mentioned there. The next chapters are about mineral springs, their genesis and quality. The last chapter summarizes the protection of natural resources. It is focused on exceptional nature reserve SOOS and it refers to general information about the geological and hydrogeological position and ecosystems found there.

Grounwater regime of the Cheb Basin
Walter, Dominik ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
This study summarizes some general findings of geological, hydrogeological, hydrological, structural and other conditions of the Cheb tertiary basin and descrides how these conditions are connected with circulation of graoundwaters and with appearance of mineral waters of different chemical composition and appearance of discharge of dry CO2. The final chapter shows information of changes of groundwater level at specific locations and periods of time by analyzing data gathered from borehole monitoring site of Czech Hydrometeorological Institute. Measuring of groundwater level was taken every day or every week, also average data of every month were taken. These data show variant changes of groundwater level which can be associated with definite events and this study shows if it is possible to associate some changes of groundwater level with exact events.

Hydrological regime of peatlands and its changes
Bachtíková, Petra ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
This thesis is concentrated on hydrology of peatlands especially on their hydrological regime and water quality. The thesis is to be regarded as a preparation for a future detailed research, which will employ the elaborate literature search. The main results therefore are the basic information about their ditribution, peatland flora and fauna and their important aspect of scientifec and practical then about hydrologii of peatland and water quality.

Isotope hydrogeology and geothermal applications to clarify the origin, the sustainability and the character of groundwater flow: Bohemian and Aquitaine sedimentary basins
Jiráková, Hana ; Hrkal, Zbyněk (advisor) ; Rapantová, Naďa (referee) ; Michelot, Jean-Luc (referee)
Isotopic investigations combined with geothermal applications represent powerful tools for the exploration of groundwater potential as a drinking or geothermal resource. This Ph.D. Thesis combines both approaches, environmental and radioactive isotopes together with temperature data in deep aquifers, in order to enrich and update the knowledge concerning the aquifer recharge processes in the Aquitaine Basin (France) and the aquifer recharge processes and geothermal potential in the Bohemian Cretaceous Basin (Czech Republic). Stable isotopes (18 O, 2 H, 13 C) combined with radioisotope data (14 C, 3 H) are used to estimate the recharge timing and climatic conditions prevailing during the infiltration from the Late Pleistocene up to modern time. The character of groundwater recharge and regime are necessary to generate relevant source data for the accurate modelling of complex groundwater systems. Three groups of groundwater recharge types can be distinguished throughout Europe - (i) continuous recharge and (ii) interrupted recharge during Last Glacial Maximum and (iii) a group corresponding to particular recharge conditions. The contrasted geographic and climate conditions at both study sites in France and the Czech Republic have entailed a great heterogeneity of the recharge conditions and...
