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.

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.

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.

Kabátek, Stanislav ; Menšík, Pavel (referee) ; Hyánková, Eva (advisor)
The task of this work is to solve rainwater management, which will be captured on the roof and on the paved areas due to the planned construction of the production factory in Hodějice village. Outflow of rainwater could glut culvert beneath railway line. Resolving rainwater management is a prerequisite for obtaining a building permit. The solution is a system of infiltration blocks with controlled drainage, which ensures the retention and not-increasing of the original rain outflow from the land. For solution manual calculation according to ČSN 75 9010 and the application from the ASIO manufacturer is used. The benefit of this work is the design of a system for automatic irrigation of vegetation on land and a system for eventual maintenance and washing of technical equipment. This will use the rainwater that would otherwise outflow meaningfully.
