Simulation model of reservoir system in Dyje river basin
Buršík, Lukáš ; Kozel, Tomáš (referee) ; Menšík, Pavel (advisor)
This Bachelor’s Thesis is focused on creating a simulation model of the reservoir system in Dyje river basin. The reservoir system consists of four reservoirs: Jevišovice and Výrovice on the Jevišovka River, Vranov and Znojmo on the Dyje River. The HEC-ResSim program was chosen to create the simulation model. The simulation model is aimed at reservoir storage function and the calculation works with the daily step. Real data of individual reservoirs and real flow series of three measuring profiles are used. The first part of work deals with simulation models and reservoir functions in general. Then the used program is described in a greater detail. The second part deals with selected system of reservoirs, watercourses and measuring profiles. There can be found a description of creating the model itself in the selected program in the third part. The description is complemented by selected examples of physical data and management rules. The last fourth part is devoted to a summary of the results, which are again accompanied by selected examples.

Design of Water Supply Facilities with the Support of Simulation Software
Pešout, Jakub ; Tauš, Miloslav (referee) ; Kučera, Tomáš (advisor)
The subject of the thesis is the design of water supply facilities with the support of a simulation software. The document is a summary of representative software tools that are used to design water supply sites directly or serve as supportive programs. A short summary of the origin, primary focus, availability and market price of each tool is listed in the survey. Furthermore the individual programs are divided into four groups. The section conveys the software's ability to deal with any of the following issues: - Water quality - Hydraulic analysis and simulation of hydraulic working - Design of water network - Creation of simulation models Subsequently, three chosen programs are subjected to exemplary tests, demonstrating some of the capabilities. The first program is Watpro, on which a design of a water treatment plant is drafted and a subsequent search for the sufficient dose of chemical additives is executed. The second program Epanet 2.0 calculates a model test of a water leak from a pipeline. The result is then compared with the outcome of equation calculation. The last program is Watdis, with which the same example of pipeline leakage is calculated and subsequently compared to the Epanet 2.0 result. The work's aim is to provide an overview of the seventeen selected programs and supply the information to potential users from the ranks of designers and students.

Uncertainty estimation of reservoir storage capacity in first stage of design preparation
Oulehla, Pavel ; Paseka, Stanislav (referee) ; Marton, Daniel (advisor)
The aim of the bachelor thesis is the estimation of reservoir storage capacity uncertainty. The input uncertainty is defined by the inaccuracy of the altitude geographic data. Using the appropriate altitude measuring and the estimated errors of the measurement, the change in the area – volumes curves is described as weel as its value of uncertainty. Afterwords the storage capacity loaded by batymetric curves uncertainty is calculated. Furthermore the uncertainty of the reservoir filling height has been quantified. For these kind of calculations the reservoir simulation model has been used, Monte Carlo method, to generate random values of the batygraphic curve has been used too. Expression of uncertainties when calculating the storage capacity can help to reduction risk of storage capacity failure, respectively reduction of water shortages during reservoirs operations during critical dry periods.

Bednář, Martin ; Sobek, Martin (referee) ; Menšík, Pavel (advisor)
The aim of the bachelor thesis is to propose a simplified way of controlling hydro-energetic function of the Mostiště reservoir. Controlling will be designed to maximize profit from the operation of the hydroelectric power plant and based on a simple analysis of the time course of the electricity price on the market. The proposed controlling will be simplified in the selected period using a simulation model.

Rajsiglová, Veronika ; Marton, Daniel (referee) ; Menšík, Pavel (advisor)
The thesis focuses on a process of water management analysis of storage and protective function of the Vlachovice reservoir on the Vlára watercourse. The work contains an alternative proposal of the reservoir storage volume in Microsoft Excel, spreadsheet program with accessible functions whereby progression of arithmetic and logical algorithm simulating operation of reservoir storage function is created. An alternative proposal of protective volume of the reservoir is created in HYDROG program, where calculations of transformation of flood waves for PV 100, PV 1 000, and PV 10 000 are performed. Moreover, the work includes simplified analysis of the hydropower potential of the proposed reservoir.

Simulation of technologies for thermal treatment of waste
Venhoda, Tomáš ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
This thesis mainly deals with the thermal treatment of waste - hazardous waste incineration and energy recovery municipal waste incinerators - their descriptions and analysis of legislative conditions. The flue gas cleaning system energy production in different operating modes is assessed by energy and mass balances. Computational models are developed for this purpose. On this basis, productions of energy from thermal treatment of hazardous and communal waste were compared.
