The thesis deals with evaluation of the Volyňka river network modification on the basis of field survey, and identification of critical stream segments, which may influence course of flood events by means of GIS analysis. Two extreme floods took place in the Volyňka river basin in the years 2002 and 2009. The paper evaluates causes, course of events and effects of the floods. To get information about river network modification the HEM-F fiels survey methodology was used. The whole stream of Volyňka river was investigated from its spring to Volyně town, the tributaries in the upper part of the Volyňka river basin and the stream Spůlka. Intensity of stream modificatin and flood effects character were evaluated and critical sections were indentified on the basis of the mapping results. The potential flow obstacles are the most frequent type of critical modification of the stream. Especially the unsufficiently designed bridges, weirs and culverts cause the most intensive damage and geomophological effects of the flood. Individual kinds of obstacles are typical for certain sections of the river flow. Modifications limitating use of retention potential of the floodplain are often present in the central and lower parts of the Volyňka river basin. In several critical stream segments there were proposed...

Tato diplomová práce se zaměřuje na modelování proudění tekutiny v paralelních distribučních systémech, kde hraje důležitou roli rovnoměrnost distribuce tekutin. Pro tento účel je vytvořen vlastní CFD kód. Kód je napsán v programovacím jazyce Java a používá ke zlepšení výkonu knihovny třetích stran, které se vyznačují přímým přístupem ke hardwarovým a systémovým prostředkům. Kód se také vyznačuje určitými zjednodušeními, u nichž se očekává, že sníží výpočetní časy. Vliv použitých zjednodušujících opatření je vyhodnocen porovnáním výsledků simulací proudění na několika geometriích s údaji získanými z podrobných modelů CFD. Geometrie použitých svazků trubek se odlišují různými uspořádáními toku a trubek a také různým počtem trubek.

Fluid flow maldistribution plays a key role in equipment used in process and energy industries, although its evaluation is often underestimated or fully neglected. Uneven flow distribution may cause thermal or mechanical load on the tube bundle, and in extreme scenarios, it can also have an adverse effect on the process efficiency. This thesis aims to find the optimal computational tools for flow distribution prediction suitable for the initial stage of the equipment design process and to identify suitable settings of these tools for their subsequent industrial deployment. The results of simplified analytical models, detailed numerical simulations, and experimental measurements were compared for the dividing header and the U-type distribution system. It was found that the results provided by simplified mathematical models, the solution of which is also significantly less time-consuming compared to detailed CFD simulations, best correspond to the measured experimental values in all modeled configurations. For arrangements with higher lateral resistance coefficient, both computational approaches provide approximately equally accurate results. However, for arrangements with lower lateral resistance coefficient, the deviation of the results obtained by CFD calculations from the experimental data is significantly larger.

This paper discusses the sources of water in the landscape, divides water features according to various methodologies and describes their nature and functions. It also deals primarily with the development of water loss from the landscape in our country and shows the history and problems of regulating rivers. It points out the consequences of these activities, discusses the historical and current measures - restoration and renaturation of watercourses and the return water back into the landscape. It also discusses the historical development of the country with regard to the aquatic. The case study deals with a model water feature - Bečva river from the source to the mouth. It describes interesting gravel flow. It analyzes the problematic sections of the river and above all the consequences that left a flood in 1997, when there was a change in the morphology of the river bed. At these new locations carried successional development of plant communities and soil creates a new profile. The author's thesis deals with these sites, especially ripping shores and gravel benches on Bečva in Osek. The paper describes the concept of river flood protection of the Bečva river, technical proposals and revitalization . The author evaluates these studies. It also shows the differences regulated and refolded channel.

Thesis is focused on thermal-insulation properties of wood fibreboards and building structure model including non-ventilated air layer. In the first part, the influence of temperature and moisture content on heat conductivity coefficient and heat transfer coefficient of wood fibreboards was investigated. In the second part, the building structure model was prepared, consisting of CLT, air layer and wood fibreboard. Subsequently, the two above mentioned characteristics were determined in dependence on measuring temperature, air layer thickness and inner surface emissivity.

This work is focused on the study of landscaping in the selected area located in the cadastral area Zbýšov. The territory was measured using a total station. The result of this measurement was a digital terrain model, which served as the basis for concept of modification to land use, care of the existing vegetation, concept of new plantings, revitalization flow accompanying restoration and riparian vegetation, the draft measure on field way reach network, concept rest places and recreational use territory. These proposals take into account the landscape-ecological and aesthetic aspects. The work also includes an economic evaluation of the proposed modifications.

This diploma thesis elaborates on the influence of constructed wetlands on macrozoobenthos of the respective recipients. Constructed wetlands near the town of Hostětín were chosen for this research project, as well as its recipient Kolelač river delta where cleaned water is drained into. The report also contains analysis of Kolelač's stream area which took place during April 2013 under the auspices of the TA02020128 project by T.G.Masaryk Water Research Institute Brno. Investigation was performed in five sites labeled L1-L5. Of these, L3 was placed in the vicinity below the outfall of constructed wetlands. The research involved a one-time collection of quantitative and qualitative samples of macrozoobenthos by the so called PERLA method. Different characteristics for each facility were analyzed in order to carry out a comprehensive survey. This included for example: abundance, amount of taxons; diversity; taxonomic composition of microzoobenthos; as well as other ecological factors of Kolelač stream quality affected by the constructed wetlands. Macrozoobenthos' studied using abiotic factors demonstrate that the L3 drainage area in closest proximity to constructed wetlands is more polluted than other locations. Analysis by a multi-metric index ranked L3 into the 3rd group, indicating that a medium ecological water quality was present, whereas other locations are ranked into the 5th group with the highest ecological quality of water.

This graduation theses describes the design of the fish ladder at the dam in Brno (district Přízřenice). In the introduction I mentioned migration patterns of fish. For a better understanding outlined and fish behaviour associated with migration, some fish undertake long voyages others migrate only a few meters. Extremely important is that for most species of fish migration is important for their survival, whether breeding or feeding. Middle part is focused for water structures and water flow, specifically to the list of dams and their distribution from different perspectives. Nowadays the progress should go ahead with nature and technical buildings. The work also has a list of fish ladders with their description and evaluation of suitability. The last part is dedicated to the design of fish passage in Přízřenice. The weir has been built on a 35,293 river km river Svratka. In this part of the work is summarized description of the location in which it is proposed fish passage. Furthermore, the list of the most abundant fish stocks at a fishing ground Svratka 3.

The goal of my thesis was to describe the processes in the chosen company. The goal was also to analyze one of the processes, specify its phases and suggest its change that would make the process more efficient for the customer and for the company. The analytical section was concerned with analyzing the processes and better specifying the chosen process and its problems. The synthetic section refers to the suggestion of new process structure, so that the chosen process better satisfies the customer and the company. The change was based on adding two new processes, identifying the possibility of production in the Production Department and identifying the possibility of assuring the material sources in the Purchasing Department. The change of the process was realized and the managers of interested Departments found it better than the ``old process{\crqq}.
