This thesis engages various methods of calculation of the spatial distribution of precipitation and the evaluation of differences in totals of rainfall in a chosen catchment. The aim of this work was to choose suitable methods for the calculation of areal rainfall and subsequently to create those methods. Most methods were developed in the GIS program. The next objective was to explore differences in monthly precipitation from hydrological years 2006 and 2007 calculated in the catchment by chosen methods. Chosen methods for the calculation of the spatial distribution of precipitation in the catchment were: arithmetic mean, Thiessen polygons, isohyetal method and inverse distance weighting method. (IDW). As a suitable catchment was selected the catchment of the Kopaninský stream where relatively dense rainfall measurement network is installed. During the solution of this thesis the area of interest had to be extended by the area between the used rain gauges which was delimited in the GIS program. The reason for an enlargement was a fact that a decomposition of rain gauges in the catchment of the Kopaninský stream did not permit the creation of isohyetal lines in this whole catchment. During the calculation and the comparison of results of individual methods was found that results of used methods were surprisingly nearly the same. It was also stated that not even sufficient dense rain gauges network does not guarantee 100% exactness for calculating the amount of the precipitation in the selected area because of their extraordinary variability.

Revitalization generally are activities leading to the recovery of ecosystems in the landscape and their stabilization. In this thesis are proposed changes for revitalization of small agro-forestry basin stream called Branná significantly disrupted trough conditions, the banks and a river basin, including throughput migration of aquatic animals.

POLÍVKOVÁ, H. (2014): Feasibility study for the revitalization of watercource in a small farmed basin, Diploma Thesis, University of South Bohemia, Faculty of agriculture, Department of Landscape Management, 67 pages. This diploma thesis deals with the study revitalization of Radimovický stream. The present work takes into account the state of the entire basin Radimovický stream. Moreover the proposal of the study revitalization describe the thesis geology and geomorphological characteristic, pedological characteristic, drainage, land use of watershed, ecological stability basin, erosion control or territorial system of ecological stability. In the design of the thesis is the water flow divided into three sections in which the individual proposals revitalization solved. The important part of diploma thesis represents tables and maps, which focus on the individual characteristics of basin Radimovický stream.

This diploma thesis deals with eliminating of bottlenecks in a production of eletrical devices, focusing mainly on the production line. It analyzes the current situation and using value stream mapping for a selected product it identifies bottlenecks of the production process. Further it proposes remedial measures to improve current situation.

Significant maldistribution negatively influences performance of equipment containing dense tube bundles and, moreover, it can cause a wide range of operating issues. This thesis therefore focuses on analysis of fluid flow in complete distribution systems via computational fluid dynamics (CFD). Data obtained from simulations carried out using the software ANSYS Fluent were also statistically analysed. Influence of system arrangement, tube bundle parameters and operating parameters on flow distribution non-uniformity and pressure drop was investigated. According to the results, system arrangement is the crucial differentiating parameter in terms of flow distribution as well as pressure drop. Additionally, data obtained via the classical CFD approach were compared with those yielded by a simplified CFD model for three selected distribution systems. Simplified CFD approach can - given its low computational demand - be utilised in optimization algorithms as well as in the course of the initial stage of equipment design process. Furthermore, this thesis discusses a simulation tool which is based on the simplified CFD approach. Although this tool is still being developed, the results it yields are very promising.

Flow distribution has big importance in equipment with limited tube rows because it provides correct operation and sometimes specific flow distribution for technology purposes is needed. This thesis is focusing on flow analysis in these units using computational fluid dynamics (CFD). For analysis of such systems models with varying tube rows and varying perforated segment lengths were created. Analysis showed significant impact of flow manifold layout along with tube layout and number of tubes. Simplified 1D model using static pressure regain coefficient was created which provides much shorter computational times. Comparison of 1D and CFD models was made to determine field of their usage.

This thesis deals with the influence of the oxide layer on the spray cooling of steel surfaces. As part of the work steel samples with oxide layer are made and the thickness, porosity and surface roughness of this layer are characterized. The average thermal conductivity of porous oxide layer is determined for different regimes of oxidation. Further, the influence of the oxide layer on the heat transfer coefficient during the spray cooling is experimentally investigated on created samples and the basic numerical simulation of the cooling is done for selected experiment with oxide layer. The thesis also contains theoretical introduction to given issue.

This diploma thesis is focused on the optimization of a specific process in the environment of the manufacturing company that supplies the components in the automotive and other industries. The theoretical part explains the principles and techniques of optimization of production processes and describes the placement of workplaces. The practical part of thesis analyzes the current state of the production process, identifies potential for improvements and proposes a new layout of workplaces. The project is then evaluated from both technical and economical viewpoint.

The main aim of the thesis was the liquefaction of Únanovka streamflow under the Těšetice dam with the focus on suitable flood protection of the villages of Těšetice, Bantice and Práče.The thesis evaluates the existing condition of the Únanovka streamflow in the river mileage 1.6593 – 6.4103. Calculation of the streamflow capacity was carried out per 1D mathematical model in the HEC-RAS programme for the selected N-year flow from the ČHMÚ hydrological study. Final value of the improved drainage from the dam was determined together with the possible value of water collection. Within the thesis the hydro-ecological monitoring of the watercourse was carried out (HEM analysis 2014).

This thesis deals with the hydroecological monitoring and river restoration of the Syrovinka watercourse in Hodonín district. In the framework of the hydroecological monitoring a river hydromorphological assessment was conducted as a part of assessing the ecological status of watercourse, to meet the requirement of the Water Framework Directive. Hydroecological monitoring was conducted using methodology HEM 2014, which is accepted as a national standard by the Ministry of Environment of the Czech Republic. Problematic reaches of watercourse were determined and for the selected reach a river restoration measures have been designed. Subsequently, an efficiency of river restoration was evaluated. The main benefits of designed river restoration are the restoration of ecological function and the support of natural water retention in floodplain.
