Assessment of water quality from wells Highlands region
Remerová, Martina ; Vávrová, Milada (referee) ; Doležalová Weissmannová, Helena (advisor)
The bachelor’s thesis is focused on assessment of water quality from wells, which are situated in the Highlands region. The thesis deals with various types of water, whereas it deals in detail with underground water. Further there are described pollutants in water with the emphasis on elements, ions and salts in samples, which were examined in practical part. Then there is given general information about wells, a reader is acquainted with the Highlands region, there is described Velké Meziříčí closely and its surroundings. Last chapters are devoted to a geological section of the locations of wells and their characteristics. The thesis contains chapters attended to taking samples and an enumeration of used devices and chemicals. There are described methods of assessment of individual inorganic pollutants in an individual chapter. There are drawn up calibrations for elements and compounds. At the end of the thesis is concentrated on results. The results of each measurement are well-arranged and compared with standards for drinking water. In most of the cases is proved that wells from given locations are not contaminated by inorganic pollutants monitored in this thesis.

The proposal for the monitoring of groundwater resources
Červenková, Martina ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The bachelor thesis follows up the analysis of current state of monitoring groundwater sources – wells, in terms of their quantitative usage and monitoring of water quality. The first part is focused on general information about usage of groundwater in the Czech Republic and in foreign countries too, ways of technical solution of groundwater captation and the description of them. In the second part there is made up the proposed model of monitoring underground water source, the way and frequency of observation of proposed parameters and the resulting demands on technical equipment of collecting objects. Then the implementation of the proposal on two specific areas follows. Finally at the end of this thesis there are described appropriate proposed procuration.

Load bearing reinforced concrete structure of apartment house
Ruber, Lukáš ; Krůpa, Pavel (referee) ; Girgle, František (advisor)
The subject of this diploma thesis is the design of the underground parts of the building. Part of this thesis is to comapare alternative designs and subsequentli evaluate the interaction of the upper structure with subsoil and pile fundantion. A detailed static assessment and implementation documentation is then prepared for the selected variant. The design of the base plate and reinforced concrete walls of the underground section are designed with respect to the crack width according to the principles for designing the white box. The theoretical part contains principles for designing and implementing a white box and evaluating design variants.

Remediation of groundwater contaminated by oil products
Kabelíková, Eva ; Úterský, Michal (referee) ; Biela, Renata (advisor)
This bachelor thesis describes rehabilitation of groundwater which is contaminated with oil products. The first part describes methods of collecting groundwater from the sources together with forms possibilities and properties of groundwater pollution and characteristics of pollutants. In addition, oil substances and their properties are described, followed by methods of groundwater protection and liquidation of accidents. At the end of the first part, ways of remediation of contaminated groundwater are presented. The second part of the thesis contains an overview of companies that carry out remediation work and description of their solution technologies.

Foundation Pits of Circular Cross-section
Plevová, Lenka ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The master´s thesis focuses on design of underground sprinkler tank for a shopping centre Sconto in Hradec Králové. The purpose of this thesis is to design and to analyse all parts of this construction. These parts are the roof, the bottom plate and the wall, which is represented by secant piles. Due to the high level of the ground water which causes a great pressure on the bottom of the tank, the solution of the bottom plate represents very important part of this thesis. There were used two programs for an analysis, Scia Engineer 2013 and FIN EC – Beton 3D. Furthermore, the work contains a view and a brief description of methods used for sheeting of foundation pits of a circular cross-section. In the end, this thesis contains the design of two other solutions of bottom plate and its economic comparison.

Návrh managementu jímacího území vodního zdroje Nová Ves u Pohořelic
Ohryzek, Dominik
The quality of the water in source Nová Ves near Pohořelice was degraded by an above-limit nitrate concentration, which caused complications with use of the water for drinking purposes. The causes of this pollution have not been fully confirmed, one of the possible factors is increased mineralisation of humus substances in the soil (Leugner et al. 2021) after deforestation of spruce and pine stands. These died gradually during the drought and bark beetle calamity in 2015 and the following years. The presented thesis propose management principles of site with respect to the water management needs of the resource owner. There were proposed phytoremediation techniques using tree species grown in a coppice manner. Management is also focused on the care of remaining vegetation in the area, where close to nature species composition prevails.

The influence of evapotranspiration on the groundwater of floodplain forests: Libický luh
Vašková, Hana ; Weiss, Tomáš (advisor) ; Slavík, Martin (referee)
The recherche part of this bachelor thesis deals with evapotranspiration from floodplain forests and its influence on the depth of the groundwater level and mineralization of groundwater. As floodplain forests in the Czech Republic are represented only in smaller fragments, there is a mention of the effect of mineralization on plants. The thesis describes the principle and use of stable isotopes in hydrogeology and the comprehensive characteristics of the area of interest of the experimental part, the Libický luh National Nature Reserve. The experimental part includes the observation of the level, conductivity, temperature, pH, and determination of the isotopic composition of the underground and surface water in Libický luh, where high mineralization of the groundwater was previously detected. The thesis discusses the effect of evapotranspiration on the content of dissolved substances in the water in Libický luh as a possible cause of this phenomenon. It was found that as the temperature rises, the groundwater level drops, and that mineralization remains relatively constant throughout the year. The drop in the groundwater level is evidently caused by intensive evapotranspiration from the floodplain forest during the growing season. However, longer time series of conductivity or hydrochemical...

Hydrogeological character of selected hardrock environments and groundwater recharge in populated areas
Krupař, Josef ; Bruthans, Jiří (advisor) ; Slavík, Martin (referee)
The purpose of this thesis is to adress the hydrogeology of hard-rock environment and groundwater recharge in urban areas. The theoretical part describes hydrogeology character of granite and ophiolite rock environment with emphasis on features such as transmissivity, storativity and hydraulic conductivity that corresponds to the fissuring of the rock environment. It is clear that fault tectonics is the most important factor that influence the hydraulic conductivity. Storativity, on the other hand, is most affected by fissured systems. Ophiolites are a more significant water supply aquifer than granites in terms of storativity. This thesis also describes groundwater recharge in urban areas and not only from precipitation but also through surface water reservoirs, leaks from pipeline network and by import of water from surrounding watershed. Practical part compares values of precipitation from 2013 to 2022 from four ČHMU stations. It compares PET (Potential evapotranspiration), API (antecendant precipitation index) values and their difference. Subsequently, in the practical part, the normalized relative groundwater recharge from the measured values of the well level is compared with the flow rate at all monitored locations and it is evaluated whether the time course of the recharge according to the...
