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.

Feasibility study of a small hydropower station within the navigation lock Přelouč II
Kratina, Jakub ; Čejda,, Marek (referee) ; Dráb, Aleš (advisor)
The content of this diploma thesis is a feasibility study of a small hydropower station within the navigation lock Přelouč II. This work builds on the framework proposal of one variation of layout arragement of the navigation lock. In this variant is considered to build a lock, which also includes a small hydropower station. At the beginning, the location of individual building objects is resolved with respect to the conditions in the locality. This is followed by a more detailed development of the building and technological part of a small hydropower plant. Part of the thesis is accompanying and technical report, drawing documentation, hydrotechnical and hydroenergetic calculations and photographic documentation.

Reconstruction of the Přízřenice weir at the Svratka river
Trněný, Michal ; Roth, Tomáš (referee) ; Julínek, Tomáš (advisor)
The Diploma Thesis deals with the design of rekonstruction of the controlled weir ´´Prizrenice“ on the river Svratka to a new gate weir structure. The first part focuses on teoretical intro and the processing of data on the area of interest and the selection of appropriate design solution for the reconstruction of the weir, where there are described several types of movable gate. As a part of sollution, there will be design of small hydro power station. At the end of this part the current condition of the buildings and the channel of the Svratka river in the area of interest is evaluated. In the second part, the Thesis deals with the design of the gate weir structure and its subsequent assessment. At first, the solid substructure and the height of the gate is designed and assessed. Subsequently, the stilling basin is designed and in conclusion, the overall stability of the designed structure is assessed.

Reconstruction of the Hranice weir
Křenek, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The bachelor´s thesis is the modification of the existing weir structure in Hranice on the river Becva at river kilometer 38,300. The first part is a search dealing with the topic of weir structures. In the second part, the locality of interest is first described. Then there is a mention of the historical development riverbed of the Becva and the original fixed weir, which goes on to describe the existing weir structure. Subsequently, the individual reconstruction proposals were evaluated and the most suitable variant was selected, including the choice of the type of substructure construction, movable valve and the fish pass. Last but not least, hydrotechnical calculations were performed, witch also contain a partial calculation of the stability of the proposed structure.

Design of Inflatable Weir in Oslavany
Kocman, Tomáš ; Moronga, Jan (referee) ; Uhmannová, Hana (advisor)
This thesis describes the current state of the river Oslava in Oslavany design and reconstruction of the existing fixed weir in the affected location. As a best alternative reconstruction of the existing fixed weir reconstruction was chosen the hard threshold floating weir inflatable weirs. The next part of the thesis describes the proposed solution, and the last part of the thesis deals with the assessment of the proposed solutions.

Gate weir design
Betlach, František ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The Bachelor Thesis deals with the study of the existing uncontrolled weir on the river Svitava in "Cacovice island" locality and with the design of a new gate weir structure. The first part focuses on the processing of data on the area of interest and the selection of appropriate design solution for the reconstruction of the weir, where there are described several types of adjustable shutters. At the end of this part the current condition of the buildings and the bed of the Svitava river in the area of interest is evaluated. In the second part, the Thesis deals with the design of the gate weir structure and its subsequent assessment. At first, the solid substructure and the height of the shutter is designed and assessed. Subsequently, the stilling basin is designed and in conclusion, the overall stability of the designed structure is assessed.

Revitalization of weir on Svratka river inVranovice with fish crossing
Jágr, Josef ; Veselý, David (referee) ; Milerski, Rudolf (advisor)
This present work deals with the design of revitalization measures for the weir in Uherčice (Vranovice) on the river Svratka. The current condition of weir constuction does not allow aquatic animals to migrate, weir constuction is transverse barrier. In this river section are found many fish species like barbel, vimba, nase and chub, for which is migration completely natural part of their behavior. There is concrete weir with a movable flap and on the right bank is located a small hydroelectric power plant. Close to hydroelectric power plant outlet is mouth of Šatava river. Weir revitalization consists of fish pass construction. Proposed fish pass is located on the right bank of the stream. There is a close-to-nature bypass channel that will ensure a continuity of water flow of already mentioned river Svratka between Věstonice lake and Rajhrad weir. Entrance to the fish pass will use a part of Šatava mount, then will continue in the artificial channel to the upstream part of Svratka river. Fish pass exit cannot breake the function of protective anti-flood embankment of Svratka river, hence there will be used block off construction. During condition of flooding will exist the possibility to shut down proposed fish pass.

Reconstruction of the weir on the Kyjovka river
Maxa, Lukáš ; Duchan, David (referee) ; Julínek, Tomáš (advisor)
This bachelor thesis deals with the study of the reconstruction of the weir on the river Ky-jovka. The reconstruction is on the site of the former draw door weir. The first part of the thesis deals with a general description of the weirs, their parts and explanation of the formu-las used for the design, followed by the selection of a suitable type of movable weir structu-re. The second part describes the area of interest and the separate design of the reconstructi-on. The mathematical calculations are presented, the design parameters are described and determined. For the reconstruction of the weir, water abstraction by the weir for the supply of the by-pass channel in the Kyjov city park was proposed.

Gated weir design
Křenek, Tomáš ; Hadaš, Zdeněk (referee) ; Julínek, Tomáš (advisor)
The diploma thesis deals with the design of a new weir structure in Valašské Meziříčí on the Rožnovská Bečva river at chainage km 3,025. In the first part of thesis, a overview of the considered weir constructions and calculation equations to be used in the practical part are summarized. In the second part, the work firstly deals with the localization and description of the object of interest and then continues with the conceptual proposal of several variants of the weir structure and then with selection of most suitable solution of the new structure. For the selected variants, hydrotechnical calculations were done, which also include a partial calculation of the stability of the proposed structure. At the end of the work there is a technical description of the aims proposed objects and an evaluation of the set goals of the work.
