The main objective of the thesis is to study artificial wastewater recharge in the area of Řevničov and reassessment of related problems such as groundwater chemical changes, colmatage, and unfavorable legislation in the Czech Republic. Individual chapters describe the experience with the above mentioned topic in the Czech Republic, but classifies it into the global context. The major part of the thesis focuses on the assessment of the qualitative and quantitative impacts of wastewater artificial recharge in the geological environment. These conclusions are drawn from monitoring changes of groundwater quality, which are controlled on the network of monitoring boreholes in the Řevničov experimental catchment. The natural attenuation of geological environment has considerable impact to final composition of contaminated water, which is compared to legal limits of underground and potable water in Czech Republic. In the research area several tracing tests were also applied, with the aim of proving the expected flow of wastewater into monitoring borehole. The obtained data specify the situation in the area of interest, or may serve as a source of information for future studies dealing with similar topics. Powered by TCPDF (www.tcpdf.org)

The dissertation thesis is primarily focused on the analysis of the properties of openings constructions with respect to infiltration in constructions, specifically related to the permeability of opening fillings and the permeability of buildings. The main aim of this work is to find out how the overall air permeability of a building can be influenced in relation to the openings and their properties, which are related specifically to the air permeability at the specified tightening degree of the used all-round fitting. In relation to the overall air permeability of the building, the energy balance of a particular building will be calculated in cooperation with the determined results of the air permeability of the building at a defined degree of tightening of used all-round fitting at levels 0%, 50% and 100%. The results of tests and measurements will be reflected in a concrete calculation of the energy balance of the assessed building in the form of numerical simulation.

Parasitic protists of genera Trypanosoma and Leishmania are members of Trypanosomatidae family. In our studies, we investigated genetic influence on infections caused by these parasites in a mouse model. These diseases are on genetic level controlled by quantitative trait loci (QTLs), when the resulting phenotype is controlled by set of genes with small individual effect. As a mouse model for mapping of QTLs controlling these infections, we used recombinant congenic strains (RCS). Each RCS carry unique set of 12.5% of the genome from donor parental strain on genetic background of other parental strain. For mapping of QTLs controlling infections caused by Trypanosoma brucei brucei (T. b. brucei) and Leishmania tropica (L. tropica) and eosinophil infiltration into inguinal lymph nodes after Leishmania major (L. major) infection, we used RCS from CcS/Dem series, where STS is donor strain and BALB/cHeA is strain of genetic background. First, it was necessary to find suitable model strains for mapping. In all three studies, we selected RCS, which exceeded range of monitored phenotype parameters in comparison with any other tested RCS or parental strains. Mice of RCS CcS-11 showed shorter survival after T. b. brucei infection and strain CcS-9 exhibited higher eosinophil infiltration after L. major infection. For...

The aim of the dissertation thesis is the assessment of the degradation of selected soil properties due to water erosion, including the temporal dynamics of these properties and the assessment of how this change affects the cumulative infiltration of the soil in watershed. Between 2012 and 2015, undisturbed and disturbed soil samples were collected on three experimental areas and the cumulative infiltration of the soil was measured. Experimental areas were selected on sloping, erosion-endangered blocks of arable land, in three cadastral territories of the Czech Republic, and this in the cadastral areas of Větřkovice, Čejkovice and Hustopeče. The cumulative infiltration was measured in three landscapes positions of the slope and soil samples were collected in three landscapes positions of the slope, at soil crust, topsoil and subsoil. In the Pedological Laboratory at the Institute of Landscape Water Management, Brno University of Technology, the particle density, bulk density, porosity, soil texture and water stable aggregates were determined from the samples taken. The cumulative infiltration of the soil was measured using the Double Ring Infiltrometer, the Mini Disc Infiltrometer and the mobile rainfall simulator. Using one-way analysis of variance to analyze the differences among soil samples and infiltration test. In addition, the dependence of soil crust formation, its physical properties and its influence on the cumulative infiltration of the soil were monitored on the areas.

: The topic of artificial recharge technology for water supply into the underground, its direct use and application in the field is becoming a more frequent foreign question, but also in the Czech Republic. This is due to the negative trend in groundwater levels over the past 10 years, caused by drought and temperature regression trends. The theoretical part of this thesis presents the knowledge of the use of artificial groundwater recharge, even with specific cases in the world or in the Czech Republic. This work is especially focused on a very specific case of the construction that represent underground dam in the village of Meziboří in the environment of the Czech massif "hard rocks". Specifically, its efficiency and impact on natural groundwater runoff. For this purpose, a numerical model was developed in the program Groundwater Vistas (extension for MODFLOW). From the results we can observe the influence of natural groundwater regime in both static and dynamic model. After simulating the dam in a steady- state regime of unaffected conditions, the groundwater level in the model before the dam increased significantly above ground level. The possible pumping without drying the collector then represents values 5,4 - 5,8 m3 /day (0,063 - 0,067 l/s) from the well just before the dam. The drain...

This thesis deals with the evaluation of hydrological properties variability of soils in forest catchment Tetřívčí brook in the source area Blanice based on selected hydropedological characteristics with respect to soil type, vegetation cover and character of slope. The selected hydropedological characteristics are maximum capillary water capacity, full water capacity, soil infiltration capability - infiltration rate and cumulative infiltration and retention potential of soils. In sum of seven soil subtypes found in forest (coniferous, deciduous and mixed) and meadow (cut and non-maintained) and on the different slope (three categories) were studied in the catchment area. This thesis is built on bachelor thesis, which dealt with the variability of hydropedological characteristics in the experimental pair comparison basins of Tetřívčí and Zbytinský brook. In the thesis were used mainly the measured data obtained from repeated field campaigns in pre- selected sites and data from the database of experimental catchments of Zbytiny. In the selected sites were made soil probes, soil samples were taken using Kopecky cylinders and infiltration measured by a single-cylinder infiltrometer. By laboratory determination and calculation, selected hydropedological characteristics were obtained. The results were...

The master‘s thesis deals with the detection of rainwater infiltration in soils using the method of electrical impedance spectrometry. Its aim is to assess the suitability of this method and equipment for measuring the role of water infiltration in soils.

The diploma thesis is focused on issues of measurement and evaluation of hydraulic characteristics of soil. In the literary research, the definitions of hydraulic conductivity and retention curve of soil moisture, their measurements in laboratory and field conditions and the prediction of these characteristics by using of pedotransfer functions. In the practical part of the diploma thesis, an evaluation of the hydraulic conductivity of soil from the experimental areas near the village Bohaté Málkovice. Two-cylindrical and mini-disc infiltration meters were used for field measurements, and a constant-gradient permeameter was used in the laboratory. Physical and empirical equations were used to evaluate the hydraulic conductivity. The results were processed numerically, tabulated and then compared.

The diploma thesis deals with measuring of infiltration by MiniDisk method and its evaluation, but also with analysis of intact and grab soil sample, by means of which it is possible to assess the soil quality. The measurements took place on 30.4.2019, 4.5.2019, 12.5.2019, 2.6.2019, 30.6.2019, 2.7.2019, 31.8.2019 and 21.9.2019 on grassland near the town of Luhačovice. Grab and intact soil samples were taken from the upper soil layer and processed in a pedological laboratory. The Zhang method was used to evaluate the infiltration results. The results of soil analyzes and infiltration were processed numerically, plotted and subsequently described and compared.

Water in porous rocks (e.g. sandstone) plays a fundamental role in their disintegration. However, the places where water enters the sandstone rocks are somewhat overlooked. At two sites in the Český ráj region, I use Karsten tube to measure capillary water absorption (CWA) of natural sandstone exposures and, using TDR (Time Domain Reflectometry) method, I study movement of water in a shallow zone of ruiniform sandstone landscape. The CWA differed up to four orders of magnitude at a distance of tens of meters, mostly depending on the type of the surface. The highest CWA was measured at highly weathered surfaces, the second most absorbent were less weathered surfaces covered with a biologically-initiated rock crust. The horizontal surfaces on the tops of the rock formations were even less absorbent, probably due to clogging by fine particles from soil. Surfaces covered with iron crust were the least absorbent. The differences between those surfaces are significant. After simulated infiltration, the maximum rate of the propagation of the wet front in the sandstone was from 5,5.10-6 do 1,9.10-4 m.s-1 measured by TDR. The water propagated at this rate only to a certain depth (the first tens of cm), but then the propagation stopped or slowed down rapidly. From a long-term measurement of volumetric...
