Urban measures of effective surface water management in urban areas
Vacková, Michaela ; Kročová,, Šárka (referee) ; Polešáková, Marie (referee) ; Urbášková, Hana (referee) ; Kopáčik, Gabriel (advisor)
One of the main challenges in promoting rainwater management into practise is the fact that it was not recognized as an interdisciplinary issue. We should seek ways how to open the problem to other professions, specially for architects and urban planners, who are the key element of its farther development. This work analyzes the reasons of this unsatisfactory state of rainwater management in the Czech Republic and it defines the possible ways how to remedy this state and outlines scenarios of its further development. The default document of the work is czech technical standard "TNV 75 9010 Hospodaření se srážkovými vodami". The new methodological guide, which is part of this work, is based on it. The work extends the range of measures which are mentioned in the standard. It brings new ways for assessing the benefits of the various measures to streamline the application of rainwater management measures in urban space.

Pre-treatment of rainwater before entering the infiltration tank
Spurný, Martin ; Balas, Jan (referee) ; Hluštík, Petr (advisor)
The diploma thesis is focused on the topic of pre-treatment of rainwater before entering the infiltration tank. The theoretical part deals with the issue of rainwater, their division and pollution, as well as technical solutions for rainwater management. In the practical part, testing of selected street drains of various construction systems in the laboratory of VHO (municipal water management) was performed and subsequently these drains were evaluated according to various criteria - the amount of captured material, drain cleaning system and filter construction.

Residential rooms and air quality
Valkovič, Michal ; Blasinski, Petr (referee) ; Uher, Pavel (advisor)
The master thesis solves indoor air quality in hotel rooms based on CO2 levels. The first part deals with indoor climate of buildings, where each form of indoor climate is described separately. The experimental part deals with CO2 level measurement in residual room, air infiltration through window and their analysis. The last part of thesis deals with results of the experiment, which are used to design and optimize hygienic ventilation, based on acquisition costs and operating expenses.

Effects of water erosion on selected physical properties of soil
Larišová, Lucie ; Toman,, František (referee) ; Hlavčová,, Kamila (referee) ; Dumbrovský, Miroslav (advisor)
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.

Study of possibilities protection against rural zone water
Burešová, Erika ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This thesis is divided into two parts. The first part of thesis deals with the problems of surface runoff, determination of surface runoff and measures to eliminate consequences of surface runoff. There is also mention of water erosion which is an accompanying phenomenon of surface runoff. The second section paper examines the threat to area in the Napajedla city of water. There are two possible solutions to the protection of the territory. For the valuation is used directive to calculate to the drain age of VMP and software HEC-RAS 4.1.0 for assassment the capacity of water equipment.

Drip irrigation of park area in multifunctional object with rainwater re-use
Kabátek, Stanislav ; Mašíček,, Tomáš (referee) ; Hyánková, Eva (advisor)
The aim of this work is to design an irrigation system of park areas in a multifunctional object using rainwater. The knowledge obtained during the study was used to solve the problem. The solution is an irrigation system consisting of drip irrigation supplemented with a sprinkler irrigation system that uses rainwater for its operation. In the event of excess of rainwater, the water is disposed of by means of infiltration blocks located on the land. The benefit of this work is to show that the return on investment is acceptable in similar cases and, above all, that this investment contributes to responsibility for natural resources.

Sanitation installations in a multiple dwelling house with underground garages
Straník, Petr ; Bárta,, Ladislav (referee) ; Vrána, Jakub (advisor)
The Master's thesis solves questions about sanitation installations in a multiple dwelling house with underground garages in Brno. The theoretical part of this work focuses on the analysis of the topic with an emphasis on the management with rainwater. The work also focuses on the possible alternative solutions of the given specialization. Technical part solves the installation of sanitary of this apartment building in the selected variant. It is a multiple storey building, where five floors are used for housing and two underground floors are used mostly for parking.

Warm air heating systems in family houses
Jankůj, Josef ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
The aim of my work on the theme “Warm air heating systems in family houses” is to summarize used systems, it´s individual components, pass judgment on preferences and shortcomings of this systems. First part is oriented on general familiarization with air rating, examination advantages and disadvantages against classic warm-water system. Second part put mind to elementary systems of airing buildings, their parting and identification with their particular principle.

Comparement of results from infiltration tests
Blahut, Dominik ; Mazáč, Petr (referee) ; Duchan, David (advisor)
The aim of this thesis is to compare the results of water infiltration from field tests, from laboratories and from numerical modeling at two selected locations. The first objective is the search procedure and the description of both sites and its adjacent areas. Further work continues with infiltration field tests using ring infiltrometer, at first theoretically for each method, and then practically with own personal measurements in the field. Further from the collected soil samples the measurements are performed in the laboratory, first in the permeameter, and followed by the grain size distribution test, from which the hydraulic conductivity is derived by using empirical formulas. At last the numerical modeling is used and all the results are compared. In the final phase of thesis the recommendations are given for infiltration at various locations and comparsion of the infiltration methods.
