Advances in applied research in the field of remediation of contaminated groundwater and industrial waste water
Kašparová, Johana ; Innemanová, Petra (advisor) ; Cajthaml, Tomáš (referee)
Water pollution is one of the most serious global problems in today's age. Contamination of water disrupts aquatic ecosystems and their surroundings. A major problem for people in some parts of the world is the decreasing availability of drinking water. In order to prevent further pollution, there are laws, mostly in developed countries, that try to protect water resources. Another procedure to reduce pollution is remediation methods. In the Czech Republic there are entities active in environmental protection deal with remediation technologies and inventories of contaminated sites such as state administration bodies, universities, academies of sciences and private entities. One of the projects that deals with research in the field of environmental damage removal is the "Environmental Research Center: Waste and Circular Economy and Environmental Safety" (No. SS02030008). A partial goal of the project is the inventory of available innovative solutions for contaminated sites for the needs of the state administration. As part of the solution of the submitted bachelor's thesis, the possibility of obtaining the necessary data from publicly available databases focused on applied research and development was verified. The theoretical part focuses on the general characteristics and protection of underground...

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

Approaches to estimate wetland evapotranspiration and the evapotranspiration loss of groundwater from wetlands in the Liběchovka and Pšovka catchments
Pátek, Karel ; Bruthans, Jiří (advisor) ; Slavík, Martin (referee)
This work is dedicated to the study of evapotranspiration in wetlands. The theoretical part is an overview of methods that are used for estimation of evapotranspiration, especially in the wetland environment. The practical part is focused on measurement of evapotranspiration in the wetlands located in the upper part of the Pšovka and Liběchovka river watersheds. Periodical fluctuations of water table and water flow in the stream were observed there due to evapotranspiration. The role of evapotranspiration was dependent on the mean daily temperature and sunshine duration. For the warm sunny days the fluctuations indicated that in the studied wetland the maximal daily evapotranspiration can cause 32 % decrease of water flow in the stream. The evapotranspiration derived from stream flow oscilation reached 86 % of potential evapotranspiration based on Oudin method. Potential evapotranspiration in the Liběchovka wetlands in summer is capable to decrease the discharge of Liběchovka in similar way as groundwater abstraction.

Geysers and their role in the groundwater regime
Pleskotová, Nikola ; Datel, Josef (advisor) ; Kubricht, Jiří (referee)
Geysers are unique and precious phenomenon in our planet. Especially hot geysers are originated only in localities where there are harmony of conditions, which are essential for their development. The main conditions are source of water, source of heat and unique system of rifts. Rifts bring the water to the chamber and vent ejects hot water to the surface. Most of cold geysers are drilled holes. Their vicinity are dappered by human, and they often look like fountains. In the introduciton of this bachelor thesis groundwater and it's movements and properties are presented. Additionally the rock environment and mineral water are covered. Geysers, the main topic of this thesis, are described as a seperate chapter. Different chapters explain how geysers work and other processes that accompany them.

Natural groundwater seeps
Hanušová, Martina ; Datel, Josef (advisor) ; Lipanský, Tomáš (referee)
The bachelor thesis is built so that all chapters themselves freely followed up. The main pillar of work is first chapter, which deals generally with springs. Next follows typology of springs, which deals with different types of springs according to geology, temperature, and yield. The special part about artesian water follows. Next section deals with karst springs and thermal springs, where I present examples from the Czech Republic. The chapter of thermal springs includes also text about geysers. In the last part the thesis deals with the Mělník area and Mělnická Vrutice. The aim of this study was to document this issue, which appears in the literature. The main result of the thesis is gathering information that appear in the foreign literature only in parts, and almost never in the Czech books and papers.

Interpretation and use of monitoring data from water supply wells
Kutnarová, Karolína ; Pastuszek, František (advisor) ; Hrkal, Zbyněk (referee)
The life of the hydrogeological well is not important only in petroleum geology but also in the water industry. Nowadays, when the demand of water rises, it is necessary to ensure the smooth running of the wells and care as much as possible about their condition. The aim of this thesis is try to apply the methods of production analysis commonly used in oil production in the oil industry for water supply wells. In the thesis I will focus on monitoring the productivity of the well with regard to increasing the hydraulic losses caused by clogging. iv

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

Radioactive medicinal springs in the Skalná - Bad Brambach area
Turnová, Štěpánka ; Goliáš, Viktor (advisor) ; Vylita, Tomáš (referee)
Radiohydrochemical exploration took place in east part of the "smrčinský" pluton between "Skalná-Plesná-Bad Brambach in years 2016-2018. The main aim of the exploration was location and thorough research of possible occurrence of waters with radioactive concretation higher than 1500 Bq/l. That is a value for radioactive mineral waters given by the "lázeňským" law number 164/2001 Sb. Most important area is Plesná-south where was discovered several springs with values exceeding 5000 Bq/l. Eminent spring is called "Břetislav-Radonka" and lies one kilometre southwest from the train station Plesná-Šneky with an activity of about 12.5 kBq / l 222 Rn and a flow rate of about 2.5 l / min. It is the most active surface discharge of radon mineral water in the Czech Republic Another significant source area is north of Skalna - north. These springs were discovered almost 60 years ago, Dr. Marie Zukriegelová. The main source of this area was named after its discoverer - the "Marie Z" spring with an activity of 5800 Bq / l 222 Rn.Further the research focused on historical radioactive conduit which were used to supply village Skalné with water. The conduit was separated on two "branches" and the younger one was built ten years after the first one. In both pipes were found radioactive waters and the most important...
