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.

Design of weir reconstruction
Němcová, Denisa ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
This bachelor thesis deals with the design of the reconstruction of a solid weir on the Oslava river, in the town of Oslavany. The introduction describes the site of interest and the choice of a suitable design solution for its reconstruction. There are several types of movable weirs and fish ladders described theoretically. Further on in the thesis, the state of the objects on the flow and the state of the river basin of Oslava, in the area of interest, are described. Another part of the thesis deals with the design of a movable baying structure (a hollow flap). An impact assessment of the current and newly proposed weir on flow in the HEC-RAS program was carried out. The project also includes the design of fish ladder and an evaluation of the stability of the newly designed construction.

Flood protection of the municipality Brantice
Zahradníková, Lenka ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with the design of a flood protection for the Brantice municipality, a part of which is an adjustment of the Opava river stream bed, specifically kilometer 77,6554 to 78,7020 and, moreover, a design of a reconstruction of the weir at kilometer 78,340. A capacity assessment of the original stream bed in the built-up area and its surroundings is a part of the thesis, as well as a measure to increase the stream capacity and a design of a boulder chute with a water gate, which replaced the original weir. The program HEC-RAS 4.1.0. was used for the stream capacity calculations.

Reconstruction of the weir in Brantice village
Filipi, Josef ; Bokiš, Miroslav (referee) ; Uhmannová, Hana (advisor)
Topic of Diploma thesis is „Reconstruction of the weir in the Brantice village.“ The theoretical part of their focus deals with the definition and putting patterns associa-ted with the design-ing reconstruction of the weir. In the practical part were made three proposals reconstructions of the weir, which are mathematically based, graphically pre-sented and discussed.

The renewal of the weir and hydropower plant Hlubočky
Hajda, Jindřich ; Rainer, Vít (referee) ; Říha, Jaromír (advisor)
This bachelor thesis deals with the design of weir and small hydroelectric power plant in lokality Hlubočky-Dukla. This thesis is dividend into two parts: a text and drawings. The text part is further dividend into three main chapters – technical report, hydro-technical and hydro-energy calculations and photos. Technical report deals with description of the site and the propřed technical solution. The individual step sof the design described by hydro-calculations. Photo documentation illustrates the current state.

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.

Hydraulic analysis in the surrounding of hydro power plant
Lorenc, Václav ; Roth, Tomáš (referee) ; Duchan, David (advisor)
The diploma thesis deals with analysis of flow ratios at the hydraulic plant Klecany – Roztoky, located in the region of Střední Čechy at Vltava river (km 37,08). At this site 3D streaming of superficial water was simulated aiming to evaluate the influence of potencial construction of the new hydroelectric power plant Klecany II on existing Klecany I. Using all of the base documentation available, 3D models of current and planned conditions were created to serve as base for calculation in FLOW 3D. The first part of the thesis describes, how the planned construction of the new hydroelectric power plant Klecany II could influence the current fairway at the inlet 400 m3/s. The second part analyses shape of planned flow hydroelectric power plant Klecany II for flow Q90d, equal to 180 m3/s. All of the results are presented in intelligible charts and images.
