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.

Influence of plan situating of weir in the prismatic channel on discharging capacity
Lukášek, Petr ; Haluza,, Miloslav (referee) ; Šulc, Jan (advisor)
This diploma thesis is focused on determination of plan situating influence of weir discharging capacity. The part of this work is a summary of the information about weirs, principally about determination of discharging capacity on normal weirs, plan deflected and plan radius weirs. Executed model research, which deals with determination of plan situating influence on discharging capacity plan deflected and plan radius weirs in comparison to normal weir, is evaluated in another part of this work. The research is also dealing with influence of aeration of the space under down surface of free jet and influence of downstream water level on discharging capacity. This work compares the results of executed research with available knowledge of other authors, who have dealt with determination of discharging capacity on weirs with different plan situating.

Influence of plan radius on discharging capacity of weir
Lukášek, Petr ; Haluza,, Miloslav (referee) ; Šulc, Jan (advisor)
This bachelor's thesis is focused on plan radius weirs. The part of this work is also summary of the information about weirs, principally about plan radius weirs. Executed model research, dealing with determination of influence of plan radius on discharging capacity of these weirs in comparison to straight weir, is evaluated in another part of this work. The research is also dealing with the effect of design of a spillway channel on capacity of the weir. This work compares the results of executed research with results of other authors, who are dealing with plan radius morning glory spillway.

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.
