This bachelor's thesis examines rainwater management in an urban intravillan, focusing on the revitalization of a former industrial brownfield in Brno. The study analyses the challenges associated with rainwater management and proposes an economical solution that benefits both citizens and the environment. The introduction provides insights into water management, including consumption, climate change, sewer line overloading, greywater utilization, and environmental impacts. The theoretical section explores the profitability of brownfield revitalization, incorporating an analysis of the former industrial area. Based on this analysis, a renewal plan for the brownfield is developed. The practical part introduces specific rainwater management facilities, addressing legislation and mathematical considerations. The brownfield is divided into sections, and the implementation of rainwater management facilities is proposed for each section. The facilities are accompanied by calculated charts and graphics for better visualization. This thesis contributes to the field of rainwater management in urban intravillan areas by presenting a practical approach to address the challenges associated with rainwater in a former industrial brownfield. The proposed economical solution aims to enhance citizen well-being and promote environmental sustainability.

Securitisation of Bangladeshi Migrants to Assam: An Analysis of India's Parliamentary Discussions
Jubaer, Md Sabbir Ahmed ; Schlotti, Jivanta (advisor) ; Aliyev, Huseyn (referee) ; Karásek, Tomáš (referee)
Among the three major political bodies in Assam, the Assamese relied on the strong support of the Bengali Muslims in their struggle over control of Assam's politics, economy, and language after 1947. This alliance was broken in the 1970s and today Bengali Muslims, who originated from present day Bangladesh, are viewed as security threats who need to be addressed through extraordinary measures. Is calling Bangladeshi migrants security threats a culmination of a securitisation process? How did the process of securitisation take shape? Who were the actors and audience? Who needed protection? Using the sociological approach to securitisation as its theoretical framework, this study analyses the mechanism of securitising Bangladeshi migration to Assam starting between the 1970s and the 2010s. Employing the method of discourse analysis, the study analyses the relevant parliamentary debates during the time frame of 1971 to 2020, in India's Lok Sabha (Lower House of India's bicameral Parliament). The project categorises the debates into different decades to grasp how the portrayal of Bangladeshis changed over time and what the different key-words used, reveal about the process. The study finds out that the Bangladeshi migrants went through a securitisation process that ended up in legitimising...

Model solution for rainwater management in selected types of residential buildings
Šoustal, Michal ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis contains a model solution for rainwater management, where certain measures are proposed for selected types of residential buildings. Its aim is to propose the economic use of precipitation for the benefit of the population and the environment. The introductory part is acquainted with water supply networks, rainwater quality and legal legislation. The theoretical part describes the individual infiltration and retention devices that are used today. The following are mathematical methods and procedures that have been applied in the research. The theoretical part also describes possible subsidy programs for the use of financial support for rainwater capture. The research began with a survey and then an analysis of the public and private space in which the buildings are located and the remaining data were performed from ČSN standards. In the practical part, hydrometeorological calculations were performed, then according to the identified legal requirements, measures were subsequently proposed for implementation. The indicative budget of the proposed measures was prepared by calculating aggregated RTS prices. Followed by subsidy contributions, which may cover part of the costs of the measures created.

Variability of hydropedological characteristics of soil type in the catchment of Tetřívčí brook
Kozáková, Jana ; Kliment, Zdeněk (advisor) ; Šefrna, Luděk (referee)
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...

Permeability of sandstone surfaces and water flow in shallow zone of ruiniform sandstone landscape
Sysel, Ondřej ; Slavík, Martin (advisor) ; Tesař, Miroslav (referee)
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...

Analysis of properties of openings with respect to infiltration in buildings
Zapletal, Miroslav ; Klepárník,, Jan (referee) ; Polášek,, Josef (referee) ; Šťastník, Stanislav (advisor)
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.
