This diploma thesis deals with calibration of hydraulic simulation models, especially with methods used for calibration and parameters that are modified during calibration. The literature review in the field of mathematical modeling, basic principles applied in hydraulic modeling and the current approach to calibration and data collection is done in theoretical part. In the practical part of the thesis, a hydraulic model of the group water supply system Horní Dunajovice is built and subsequently calibrated. The calibration is first performed manually for the normal operational status and then using a calibration software created for this purpose for a load case with high velocity.

In modern point of view of waste management is desirable to effectively process the grates possible amount of wastes. Sediments from cleaning of mined lime stones contains a lot of clay components, but there is also indispensable share of soft calcite. This composition makes these sediments a promising material for preparation of hydraulic binders. Production of common hydraulic binders, especially Portland cement, is very energy-intensive plus loads environment with considerable amount of combustion gases, therefore it is necessary to explore possibilities of alternative low - energy binders production and usage.

This thesis addressed the development renders the optimal ratio of thermal insulation and mechanical properties. In developing these materials were used alternative latent hydraulic binders. Research was conducted plasters and renders the requirements of technical standards in the Czech Republic. Work dealt with the general composition of plaster, including the use of secondary raw materials in dry plaster mixtures and thermal insulation properties and remediation plaster. Furthermore, the measured values of physical and mechanical properties of the test formulations. The best recipes were compared with plaster on the Czech market.

Hydraulic characteristics are the most important properties of soil, i.e. retention curve of soil moisture and hydraulic conductivity. Hydraulic conductivity of soil characterizes the ability of the soil to conduct water. Retention curve expresses the relationship between moisture and moisture potential of soil. The running of retention curve is influenced by many factors, eg. grain size and mineralogical composition, content of humus, reduce bulk density and structure of soil. Measurement of retention curves takes a lot of time and money in laboratory conditions therefore pedotransfer functions seem to be an alternative solution. The thesis aims to estimate moisture retention curves of soil in a selected area of interest in South Moravia using program Rosetta (Schaap, 2003). Data of granularity (% content of clay, sand and dust), bulk density of soil and hydrolimits field water capacity and wilting point were used as predictors in individual models of program Rosetta. Data of grain were matched by FAO / USDA system. Retention curves of soil moisture were measured on a sand tank and overpressure devices. The measured retention curves were parameterized by RETC program. Estimated retention curves were graphically compared with measured to determine the quality of the estimate. The accuracy of the estimate was assessed by correlation coefficient R of determination coefficient R2 and standard error SMRE. Usability own derivatives pedotransfer functions is hard to say due to the size of the input data file. I would recommend further verification of data at the other localities in south Moravia.

Thesis deal with design of drop-hammer and especially its carriage (frame) for direction equipment for driving various thin-walled profiles in civil engineering. The entire drop- hammer is used as an additional adapter for construction machine. The first part of thesis contains design options, description of chosen option, including principles of work with drop- hammer. It also contains the calculation which are important for design of parts of drop- hammer, frame strese analysis by computer software, the approximate production coast of drop-hammer and summary of the parameters of the final product. The annexes contains the specified drawings and examples of 3D models of assemblies.

Purpose of this thesis is to make constructional modification of single-purpose pressing machine for Huisman Konstrukce, s.r.o. company. Present machine is non-operational and not enough powerful for present requests of workshop. Intended modifications are to describe present condition of machine, find present requirements and design simple modifications. All modifications are checked by calculations and sketched in shop drawings. There were also made alternative options of modification to show machine more versatile and automatic.

This thesis deals with the structural design dividing equipment for producing blanks for forging. Its contents are designed technological, structural design, design and check calculations needed for the actual construction of the dividing device. The conclusion of the work dealt with a dangerous place for the operation and maintenance of the machines by analyzing significant hazards. The result is the structural design of machine parts according to the assignment.

The Ph.D. thesis deals with the preparation of highly hydraulic binders based on roman cement. Roman cement (natural cement) is recently not available on the market due to uneconomic production of such a specific binder. On the other hand there is a big lack of information on this hydraulic binder. These results in failure in meeting the basic principle of modern approaches to restoration of historical buildings or monuments made of such kind of materials, which is such, that the materials used for restoration should be compatible with original material. Recognition of the processes of roman cement preparation based on progressive methods of study can provide substantial information for more efficient raw material selection or even for nontraditional utilization, for example for artworks. This work hence is aimed at studying and selection of traditional natural as well as nontraditional raw materials such as clay. This work also studies the preparation of highly hydraulic binders based on roman cement and the kinetics of burning and hydration processes

The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a theoretical research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation. Furthermore it provides basic theoretical information on numeric simulation of the dissolved materials motion and transport in the soil. The last chapter of the theoretical part describes the calibration of the simulation by the HYDRUS 2D software. The second part of the thesis is devoted to the formation of filtration columns placed in the chosen site of the root zone wastewater plant. Within the filtration columns the automatic irrigation was formed and set off. Measuring of humidity in filtration columns was taking place for 81 days as well as the water sampling after the flow through the soil horizons. On the grounds of the measuring results the calibration of numeric simulation was carried out by the HYDRUS 2D software. The last part of the thesis presents the applications through the extending and alternation of the modelled setting. The main aim of the thesis is to calibrate the model and propose a general solution to advancement at realization of irrigation details when using the treated wastewater for the purpose of irrigation.
