Small hydropower plants in the Czech Republic
Bursa, Ondřej ; Preisler, Lukáš (referee) ; Sitek, Tomáš (advisor)
There are more than 1,600 hydroelectric power plants in the Czech Republic. Almost all of them belong to the category of small hydropower plants. This thesis summarizes the current state of small hydropower plants in the Czech Republic and the possibilities of future development. Furthermore, the work contains a description of the situation of the Svratka river, gathers information about the already installed power plants and outlines the possibilities of further progress.

Water wheels
Klezla, Vojtěch ; Štigler, Jaroslav (referee) ; Haluza, Miloslav (advisor)
Water wheels are the topic of this bachelor thesis, which is divided into three parts. The first one describes a history of water wheels. The second part is focused on different types of water wheels and basic part of water construction. In the last part is concept and calculation of overshot bucket water wheel and adjustment of the parameters of Poncelet water wheel.

Portable water pico turbine design, production and basic parameters verifying
Tománek, Ladislav ; Haluza, Miloslav (referee) ; Štigler, Jaroslav (advisor)
The aim of this diploma thesis is to design, manufacture and measure the characteristics of a mobile water pico turbine. More precisely, it is an experimental construction of a mill wheel. The first part of this document is describing the design and manufacture of the turbine. This part focuses mainly on the construction of water wheels with different sizes of buckets and on the nozzle supplying water to the turbine. There is also a CFD simulation of pressure loss of nozzle. The second part of the thesis is focused on the processing of data that were measured in the laboratory, including the determination of uncertainties. The measurements were performed for different turbine settings such as flow, speed, different wheel shapes and different positions of the nozzle distributing water to the wheel. For individual turbine settings are created characteristics, from which maximum powers and maximum efficiencies parameters are determined.
