The Revitalization of a Small Watercourse
Svědínková, Renáta ; Moronga, Jan (referee) ; Uhmannová, Hana (advisor)
My diploma thesis deals with the issue revitalization of a small stream. Assessment and design of revitalization is done on Kuřimka stream which flows through the cadastral territory of the Moravian Knínice - Chudčice - Kníničky. In the diploma thesis were designed several of revitalization measures: stabilization of longitudinal tilt with the use of stone steps in the bottom and wooden thresholds, sedimentation reservoir for capturing sediment and slope stabilization using willow fences and gabions. Proposal of revitalization measures does not deteriorate runoff conditions.

Numerical modelling of flow over auxiliary spillways
Kostelecký, Jiří ; Golík,, Pavel (referee) ; Zachoval, Zbyněk (advisor)
The thesis deals with possibilities of numerical modelling of an overflow over selected types of auxiliary spillways and then the possibilities are verified in particular localities. In thesis, there is carried out the determination of capacity of selected spillways by using several methods: the calculation of the overflow equation, one-dimensional and two-dimensional numerical models and physical model. The author created parametric analysis to each single method. Parametric analysis represent various hydraulic conditions. Subsequently, there is possible to express the effect of parametric analysis. The author makes a comparison of water levels received by mentioned methods set out under the specific hydraulic conditions by calibration of each model with the physical model. Finally, author recommends values of all coefficients which have an impact on results of numerical modelling of the flow over selected types of weirs mostly using like auxiliary spillways.

Hydrodynamic model of the Odra river in the locality of Odry
Skokan, Jiří ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The Bachelor's thesis deals with creating 2D hydrodynamic water flow model of Odra river in the locality of Odry (km 85,779 - 93,645). Using a numerical model HEC-RAS 6.2, hydraulic calculations of the peak flows of Q5, Q20, Q100 and Q500 were performed. The outputs were processed in the form of flood hazard maps, threat maps, written profile and drawing documentation.

Revitalization of the selected section of the River
Bakala, Filip ; Petr, Pelikán (referee) ; Šlezingr, Miloslav (advisor)
This thesis deals with revitalization of the selected part of river Drevnice. Main scopes of the work are proposals of fish passages through migration barriers. The work is conceived on four levels. The first of them is dealing with the general characteristics of selected segment and with description of objects on watercourse. The second level is dealing with revitalization, where the basic information about migration and efficiency of fishes are described. In this chapter basic distribution of fish ladders is included. In third part, which is the most comprehensive, I design a boulder fish ramp and bypass channel. The last chapter contains drawings documentation of watercourse Drevnice and my own proposed revitalization elements.

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.

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 measures at upper reaches Svratka River
Klepárníková, Radka ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the proposal of measures on the Svratka stream in the cadastral area Český Herálec and Herálec na Moravě. The aim of the diploma thesis is to propose appropriate flood protection in the Herálec urban area and to elaborate proposals of nature friendly measures outside the municipality’s built up area, which will enable the renewal of the ecological functions of Svratka in the spring area. In the diploma thesis the assessment of the current state of the watercourse in the analyzed locality was caried out and also the assessment of the capacity of the watercourse and the objects on there. Furthermore, the flood levels and its areas were determined. Hydraulic water flow calculations were performed using the 1D and 1D/2D numerical model. For calculation, HEC-RAS 5.0.3 was used. When processing a 1D/2D numerical model, a manual describing the progress of work in the HEC-RAS 5.0.3 program was also created. On the basis of the results from the numerical model, a proposal for flood protection measures in the urban area and nature friendly measures in the extravilan was carried out.

Design of water reservoir for flood protection
Vláčil, Lukáš ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this thesis is to map an anti-flooding protection in locality Dobrá Voda near Hořice and to create suitable plan of a water retention reservoir. Retention reservoir works as a system for holding and transformation of flood wave and thus for dealing with floods. First part of this thesis covers general description of issues of floods, current legislature, anti-flooding measures and a description of flood wave transformation. Methods for determination of retention seepage of the reservoir are described in this part as well. Computer programmes (HEC-RAS, Transformwave) were used for the purpose of above mentioned determination. In the second part of this thesis the given locality is described including all the possible risks and plans of convenient anti-flooding measures. The results of appropriate software determinations are compared in this part of the thesis as well. A final plan of a suitable retention reservoir is based on the results of comparison.

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.
