Conceptual design of a hydroelectric plant on the Liwagu River in Malaysia
Hamsová, Adéla ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The bachelor thesis deals with the conceptual design of a small hydropower plant on the Liwagu River in Sabah Province, Malaysia. The background and site survey was provided by Stream Ltd. The work included the design of the intake structure, intake pipeline, engine house and its process section. A suitable type of machine was selected for the hydropower plant. At the end of the work, an economic analysis of the project was prepared. In terms of payback, the project was evaluated as beneficial. The bachelor thesis includes a calculation part, a drawing part and a photo documentation of the designed site.

Shaft spillway capacity depending on flow stages
Monsport, Jakub ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The first part of this bachelor's thesis is drafted as a search. Summarizes information about spillways and in more detail focuses on shaft spillways and describes not only their construction but also flow stages in a funnel, shaft, elbow and at the beginning of the tunnel. The second part is practical and consists of the measurement of Q/h characteristics on the model of shaft spillway with some modifications.

Safety Assesment of the Rouchovany Dam during Floods
Menšík, Kryštof ; Jobánek, Stanislav (referee) ; Jandora, Jan (advisor)
The main goal of the bachelor’s thesis is the safety assessment of the Rouchovany Dam during floods in accordance with ČSN 75 2935. The thesis contains information about hydraulic structure itself and of its segments, hydraulic calculations, set up permissible water level and control maximal water level. The result of the thesis is the evaluation of current condition of body of hydraulic structure and proposing corrective measures.

Technical design of an alternative to the small hydropower plant Ejpovice
Mitrega, Stanislav ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
The main purpose of this bachelor’s thesis is a new design of a small hydroelectric power plant Ejpovice with non-pressure and pressure derivation. The non-pressure part of a waterway includes design of a weir, culvert and an inlet channel. The pressure part of a waterway includes an intake object and an original tunnel. The design review includes two variants of a waterway. In the first variant water is running straight through the tunnel. The second variant is considering with a glass reinforced pipe that will be installed in the tunnel so the tunnel won’t be flooded. At first the thesis analyses all the sources for the preparation of a design and discribes an area of interest. Below the thesis presents a design of all the new building objects and technological equipments. Detailed restoration of the tunnel is also described. In conclusion of the thesis, there are calculations of a power generation and an economic analysis of both variants. The payback period of the second variant is significantly longer than the period of the first variant although an alternative design doesn’t require a comlicated restoration of the tunnel. On the basis of this fact I recommend to implement the first design.

Safety Assesment of the Vacenovice Dam during Floods
Svoboda, Jiří ; Jobánek, Stanislav (referee) ; Jandora, Jan (advisor)
The main goal of the bachelor’s thesis is the safety assessment of the Vacenovice Dam during floods in accordance with standard ČSN 75 2935. The assessment is accomplished for the control flood wave KPV100, PV200 a PV200 [13]. In the introduction of the bachelor’s thesis are described particular parts of the Vacenovice Dam and the subsumption of the Vacenovice Dam to relevant categories. The next part includes basic data of the Vacenovice Dam, used hydrologic data, description of hydrological calculations, setting of maximum permissible water level and control maximal water level. Then the thesis introduces a comparison of these water levels. In the end of the bachelor’s thesis are mentioned possible measures leading to increasing of the safety of the Vacenovice Dam.

Safety submersion depth of small hydro-power plant Vydra 2 inlet
Jobánek, Stanislav ; Žoužela,, Michal (referee) ; Šulc, Jan (advisor)
The thesis deals the measurement results on a physical model of the inlet part of the small hydro-power plant Vydra 2. The influence of the shape and location of the intake into the pressure pipe of small hydro-power plant Vydra 2 with respect to the water surface state was analysed. The work also deals with possibilities of using devices to eliminate the generation of vortex of higher intensities.

Shaft spillway water tunnel capacity increasing
Monsport, Jakub ; Jobánek, Stanislav (referee) ; Šulc, Jan (advisor)
In the first part of this diploma thesis, the problem of supercritical flow is described, as what phenomena occur during it and what dangers it brings. The research part continues with a list of structures in the supercritical regime and their modifications, which should eliminate the danger occurring during supercritical flow. The second part of the diploma thesis is practical and presents the measurement of the course of the water level in the tunnel of the shaft overflow on a physical model with different modifications of the initial section of the tunnel due to the search for the most suitable modification, which would ensure a sufficient reduction of dangerous phenomena occurring during supercritical flow. As part of the practical part, in addition to measurements on the physical model, calculations in numerical modelling were also performed using the Flow-3D program.
