Design of the gated weir
Skřička, Jakub ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The Bachelor Thesis deals with the study of the existing uncontrolled weir on the river Svitava in district Brno-Obřany. The first part of the Thesis contains a theoretical part about theme of weirs. In the next part Thesis describes the current state of the area of interest, including the riverbed of Svitavy with neighboring objects. After that the Thesis describes the design of the reconstruction, including the selection of suitable movable construction and procedure of hydrotechnical calculations. In conclusion, a calculation of the stability of the design was described.

Small Hydropower Plant Project
Košíček, Jiří ; Šlezingr, Jan (referee) ; Radil, Lukáš (advisor)
This bachelor thesis consists of a description of the legislative framework of small hydropower plants, which is necessary to know for their operation and construction. It also describes the general theory of small hydropower plants, specifically describes the individual technical elements - weir, gratings, sluice gates, ambushes, sand traps and stones, open flume, pipes and stilling basin. Another part assesses the economic feasibility of small hydropower plants for specific hydrological conditions and design of turbines on suitable work flow. The main part is devoted to specific proposal small hydropower plants in the village Tulešice by the river Rokytná.

The design of swirl turbine for the concrete locality for ČEZ
Šebela, Radek ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
This thesis deals with the design of water turbine enabling optimal utilization of hydro-energetic potential of given location (barrage on Úpa river) chosen by ČEZ a.s. company. Moreover, the option of multi-unit layout is discussed. Because of the low-head profile of given location, the technology of swirl turbine in siphon configuration was chosen. Technology of swirl turbine presents new modification of Kaplan turbine with no need of guide vane. Swirl turbine is characterized by its high discharge and high speed. The main part of this thesis is focused on hydraulic design of the turbine.

Design of small hydropower plant for specific location.
Paštěka, František ; Rudolf, Pavel (referee) ; Štigler, Jaroslav (advisor)
This master's thesis is specialised in designing of small hydropower plant for specific location. In work should be designed suitable turbine for parameters found on the site, then created a basic project documentation of small hydropower plant with all devices and used principles, so that the plant would be capable of operation. In the next part of thesis should be extented the calculation of flow in the turbine delivery and assessed effect of geometry of turbine delivery on the flow.

Feasibility study of the small hydropower station
Patočka, Filip ; Neumayer,, Oldřich (referee) ; Dráb, Aleš (advisor)
The aim of the present master’s thesis is to explore the feasibility of small hydropower plant for cur-rent hydro energetic potential of the weir on Ohře river, located in the city of Terezín in Ústecký re-gion, Czech Republic. The target of the thesis itself was to design minimally two variants of constructional and technological part. Due to requirements related to maintaining of all functions of the weir construction was decided to design small hydropower plant completely under the water surface, with flap mounted to the roof of the hydropower plant. Part of the thesis was also an economical assessment of designed hydropower project.

Screw turbine form small hydro-power plant
Sklenář, Vít ; Hrnčířová, Michaela (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is the research of small hydro power plants, design of main structural dimensions of screw turbines for small hydroelectric power plant and the subsequent evaluation of the economics of production. The thesis is divided into four main parts. The first part deals with general information about small hydropower plants. In the second part the screw turbine and its accessories are introduced in details. In the third part the screw turbine is designed for a specific location. The fourth section compares the possibilities of manufacturing hydrodynamic screw.

Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.
