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.

Design of weir reconstruction in Oslavany
Němcová, Denisa ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
This diploma thesis deals with a design of the reconstruction of a smixed weir on the Oslava river in Oslavany town. The introduction describes the site of interest and the the occurrence of ice events. There are several types of fish ladders described theoretically. Further on in the thesis there is desribed the state of the objects on the flow and the state of the river basin in the area of interest of Oslava river. Next part of the thesis deals with the design of a movable baying structure (a hollow flap) and fish ladder type bypass channel. 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 basin adjustment in overweir and an evaluation of the stability of the newly designed construction.

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.

Design of a weir structure with movable locking elements
Staněk, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The aim of this Bachelor thesis is the design of the movable barrier structure on the site of the existing fixed weir in the city district of Brno - Husovice on the Svitava River in km 7,820. The first half of the thesis deals with theoretical aspects concerning the design and utilization of weir structures. In the second half of the thesis, theoretical knowledge is applied to practical design of the moving weir structure. First of all, the locality of interest including adjacent objects is positioned and described. Subsequently, a critical evaluation of the scope and quality of input materials is performed. The following is the selection of the appropriate type of substructure construction and movable valve. Based on the chosen type of construction, hydrotechnical calculations are performed, which include partial assessment of weir stability. The thesis also includes drawings and summary description of the designed structure.

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.

Reconstruction of the inlet channel to the turbine
Hanuš, Roman ; Perla, Jan (referee) ; Strnad, Jiří (advisor)
The subject of this bachelor's thesis is designing the reconstruction of the watercourse leading to the mill complex in the Bohumileč village in Northern Bohemia. A proposal for a new safety weir has been developed on the watercourse, connecting to the existing dam with its original weir in an unsatisfactory state. A diagnostic survey and assessment of the original reinforced concrete channel in the former mill building, which has been supplying water to the water turbine since 1914, have been conducted.

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.

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.
