Mineral water resources in the Czech part of the Vienna basin
Bošková, Lucia ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
The bachelor thesis characterizes the Vienna Basin region from a geological and hydrogeological perspective. The main focus is put on the occurrence of mineral water. It describes the basic types of waters that are located there. In a closer look, it describes important types of them, mainly those ones that have the largest occurrence in the region. In another aspect, it analyzes their current condition and use. It defines basic concepts of this issue and describes common or legislative requirements for the classification and description of mineral waters. It puts a closer look and describes main sites of mineral water springs, including local spa places, especially those ones that are currently active. It also briefly deals with localities, where mineral water abstraction or spa treatment took place in the past and which are currently no longer active. In the end, it describes these sites from a balneological point of view. Keywords Vienna basin, mineral waters, spa, balneology
The issue of lithium in waters in Czech Republic
Sedláček, Alexandr ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
The aim of this thesis is to present a survey on the genesis and the occurrence of lithium in rock environment in the Czech Republic on the basis of Czech and foreign literature. The thesis delineates the most important localities with the occurrence of lithium compounds along with the current condition of these deposits. In the second part of the thesis, I composed similar research of all accessible studies dealing with the problematics of the presence of lithium in drinking water and its impact on the health of the population. At the end of the thesis, I created a proposal for water management monitoring. Its aim is to obtain the most accurate data of lithium levels in drinking water and of the amount in which it is consumed by the monitored subjects. The monitoring was designed so that the output data could be compared with medical records of the monitored population and the exact relationship between the concentration of lithium and its impact on human health could be determined.
Individual groundwater supply in hard rocks - factors affecting yield
Kvíz, Jan ; Hrkal, Zbyněk (advisor) ; Datel, Josef (referee)
The aim of the bachelor thesis is to characterize the natural groundwater resources in the crystallin massif, forming ¾ of the Czech Republic. In the form of research, it summarizes the knowledge of this issue regarding the nature-science and socio-economic context. The introduction of the thesis describes the specific environment of hard-rocks and the factors affecting the yield of sources. It focuses on the region of the Czech Republic. In the following part, the thesis describes the individual groundwater supply in the Czech Republic. Is summarizes the Czech legislation of this issue, the development of the individual water supply and also his negatives. The thesis then focuses on some of the examples of the exploitation of groundwater resources in India, which is one of the most active theoretical and practical innovators in the field of exploiting the region of hard rocks.
Relations of the carbon dioxide occurrence and geologic conditions of the Cheb basin
Pavlát, Jan ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
This bachelor thesis describes the area of the Cheb basin which is situated in the Western Bohemia, and shows the geological, tectonic, hydrogeological structure of this area. The main feature of the bachelor thesis is a CO2 emission in the Cheb basin, near the village Dolní Částkov but it also describes the occurrence of mineral waters in the vicinity of the chosen lokality. Furthermore, the bachelor thesis deals with the emanation of gases in groundwaters. The bachelor thesis describes the properties and occurrence of CO2. At the end of the bachelor thesis, there are results of my measurements in a regular network of points with a device Meopta DI-2 654-03, which serves for an air sampling and measures the concentration of CO2 expressed in percentages. Key words: carbon dioxide, the Cheb basin, geological conditions, mineral water
Artificial recharge of groundwater resources
Drmota, Adam ; Datel, Josef (advisor) ; Hrkal, Zbyněk (referee)
This thesis addresses artificial replenishment of groundwater resources, commonly known as artificial recharge. The idea of artificial replenishment of groundwater lies in man-induced transfer of surface water to underground aquifers. The introduction highlights the reasons that led humans to artificially replenish groundwater. In addition, individual methods of surface, subsurface and induced infiltration are described. A special chapter was devoted to natural factors limiting the use of these methods. The thesis also includes studies of three concrete examples of projects of artificial recharge into groundwater by various techniques, each time with a different intention. Specifically, it describes resisting the intrusion of salt water into the Delta Llobregat aquifer in Spain, using the appropriate geological structure as a reservoir of potable water for the drought in South Florida, and the use of artificial infiltration basins and bank infiltration for water use in Káraný, Czech Republic.
Ensuring water quality in small water supply systems
Klapka, Miloš ; Datel, Josef (advisor) ; Tylš, Michal (referee)
3 Abstract Providing drinking water to a large number of rural population, small water systems are the backbone of water supply in rural and remote areas. Therefore they constitute a significant part of public infrastructure. Facing various difficulties, small water systems operators often find it hard to reach and maintain high quality of drinking water comparable with quality achieved by large water suppliers. This thesis focuses on ensuring water quality from a hydrogeological point of view. In its theoretical part the thesis defines small water systems, summarizes legislation concerning small water systems operation, identifies main causes of unsatisfactory or unstable quality of provided water and discusses possible improvements. The empiric part of the thesis suggests particular steps how to ensure sustainable drinking water quality in specific location. The suggestions are based on archive data research, results of exploratory works and evaluation of hydrodynamic pumping and infiltration tests. The main contribution of the diploma thesis is a summary of the existing knowledge and summary of the possibilities of improving the current adverse situation in small water systems and their practical application in a specific location. Keywords Small water systems, drinking water quality, water supplies,...
