Proposal for the nature friendly measures on the river Svratka in Židlochovice
Serafin, Petr ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
The bachelor thesis included the assessment of the current state of the channel on the Svratka river in the interest section from river kilometer 27,059 to river kilometer 29,751 in the cadastral area of Židlochovice city. The channel was judged on the line of N-year flows by 1D mathematical model HEC-RAS version 5.6.0. On the basis of the results of the flow, which has proved capacity of the channel on the design discharge Q20 in built up area, was suggested nature friendly measures on the river and neighboring area near the river consistent with plans from Povodí Moravy.

Regulation of the streambed Hloučela
Vysloužilová, Lucie ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
The thesis describes the evaluation of the present situation of the watercourse of Hloučela river, that is situated in Plumlov village. The trough is situated in the urban area on km 11,831-11,991. The capacity of the present and newly suggested trough has beed worked out using the HEC-RAS program. The thesis contains the evaluaion of the trough stability based on the calculation of non-eroding speed as well as the proposal of measures against strong silting of described area. There are another methods that could be used for soluting the trough stability described.

Proposal of measures on Hodonínka river
Ondrišík, Ivan ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The content of this bachelor's thesis is focused on assessing the condition of the riverbed of a river Hodonínka, which flows through the built-up area of the village of Olešnice, Křtěnov and the vacant area of the village Crhov. The assessment includes an assessment of the current condition of the riverbed and the condition after adjustments with the proposed flood control measures. The proposed modifications are supposed to ensure the protection of parts of municipalities against twenty years of water Q20 = 16,74 m3/s. The section of interest of the stream is located on the river kilometre 13,018 - 14,638 and extends into three cadastral areas. The mathematical model HEC-RAS 5.0.7 is used for hydro-technical calculations, which works in a 1D environment.

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.

Assessment of runoff conditions on the river in the Morava River Basin
Serafin, Petr ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The aim of the diploma thesis was to assess the curent state of the Svratka river and propose appropriate measures in accordance with the plans of Povodí Moravy, s.p. Locality of interest is located in the built-up area and non-urban area part of Herálec at river kilometer 163,9809-164,5189 and extends over the cadastral areas of Český Herálec, Herálec na Moravě and Svratka. The assessment of the river was performed on the flow series using the 1D mathematical model HEC – RAS version 5.0.6. On the basis of the results of the flow rate, was the locality od interest divided into four parts. For parts which are located in the urban, was designed a flood protection against of the 20 – year flow. For parts which are located in the non-urban area, was designed revitalization with the possibility of water retention in the landscape. The final design was verified by calculation in the same program HEC – RAS. The diploma thesis contains text part, calculation part and drawing part documenting the proposed measures.

Proposal of nature-friendly measures on a selected watercourse
Lach, Radek ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The main aim of the diploma thesis was an assessment of the current state of the Svratka watercourse flowing largely through the urban area of the town of Jimramov, especially the adjacent parts of Sedliště and Benátky, and to a lesser extent through the suburban area below the municipality. The given section is 2,6 km long with the beginning in the river kilometer 131,10 and the end in the river kilometer 133,70. The capacity of flows and objels in the given period has been assessed (bridges, weirs, steps, etc.). Calculation water surface profiles have been made by usage of the 1D mathematical model HEC-RAS. Part of the work was to determine the current level of flood protection on the stream. The assessment is based on personal visit and photos taken as rekord. The thesis was complemented with hydroecological monitoring of the stream channel – the HEM analysis 2014. The final phase of the work deals with the conceptual design of a nature-friendly flood control measure to increase the protection of the adjacent area and improve the condition of the watercourse. Progress of individual levels and measures are based on hydrotechnical calculations.

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.

Proposal of measures on Svratka river in the cadastral area of Svratka
Černý, David ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The diploma thesis focuses on the assessment of the current state of the Svratka watercourse and of the capacity of the existing objects on the course, which is partially modified in the solved locality and includes both – intravarian and extravarian areas of the town. Within hydrotechnical calculations, the 1D mathematical model HEC-RAS version 5.0.6 was used to determine the course of levels. The thesis focuses also on suitable design of flood protection measures on the river Svratka with protection for design flow Qn = Q20 = 28,6 m3 / s.

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.
