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.
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.
Possibilities of banks stabilization of Desná watercourse
Lach, Radek ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The thesis includes the assessment of the current state of the Desná watercourse in the cadastral area of Velké Losiny and the subsequent suggestion of the remediation of two solves sites in the solved area.The river falls under the management of Povodí Morava, s.p. and for the most part it flows through built-up area of Maršíkov. To assess the current state of the river bed, a personal tour of the area of interest was conducted, during which everything was digitally documented. To determine the river bed capacity and calculate the progress of individual levels with the inclusion of all existing objects on the flow in the solved section, the 1D program HEC-RAS was used. Level flow calculation was made for one-year, five-year and capacity flow. Based on the literature search, measures were proposed to remediate bank erosion in locality 1 and locality 2. In these locations, an ideological nature-friendly measures in the river bed were proposed.
Flood protection of the municipality Březová nad Svitavou
Cetkovská, Lucie ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The diploma thesis is focused on the assessment of the stream and the proposal against flood risk in the location of town Březová nad Svitavou. The stream Svitava flows under administration of Povodí Moravy. s. p. The stream Svitava flowing through urban area, has a high potencial flood risk. The current situation of a section of the stream is assessed based on defined data and personal inspection. On the stream, there were provided the measurements by the method of HEM. Capacity of the stream along with the objects for the particular section were calculated in the software HEC-RAS. Based on the results, there have been designed the flood protection. The final design was verified by the calculation in the program HEC-RAS.
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.
Proposal for the nature friendly measures on the river Bobrava
Mláděnka, Jakub ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The aim of the diploma thesis is to describe and evaluate in detail the current state of the Bobrava river in the interest section – river kilometer 1,832-5,743. Part of the work is to assess the capacity of the river flow and the objects connected with it and find the class of an actual safety at village Zelesice. The calculation of the flow rate is performed by using the 1D mathematical model HEC-RAS for selected N-year flows. On the basis of the results of the flow rate, it is made the idea of natural freindly flood protection before the value of the 20-year flow. The result is two variants of river basin adjustment, when each one is leading to make Zelesice safer place and to improve the current state of the river Bobrava.
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.
Assessment of the water flow in the Vltava river basin
Černý, David ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The bachelor´s thesis includes the assessment of the current state of the channel Drnový potok as well as the objects in the solved section from river km 5,972 to river km 7,021. The 1D mathematical model HEC-RAS version 4.1.0 is used for the calculation of the course of level and for the assessment of the channel capacity, including the objects connected to it. The work also deals with the ideological proposal of near natural flood protection measures in the municipality of the village Luby on the design discharge Qn = Q20 = 51,80 m3/s.
