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.

River regulation with regard to the flood protection and revitalization
Kuneta, Tomáš ; Petrula, Lubomír (referee) ; Duchan, David (advisor)
The bachelor thesis is focused on the assessment of the part of the Svratka River. River Svratka flows through the city Brno. Area of interest is located in the southern part of Brno, specifically in the Brno - Modřice district. Hydraulic calculation is based on available geometric and hydrologic documents. The Svratka River Capacity Assessment was performed using 1D model in the HEC-RAS. Flood protection measure was designed based on the hydraulic calculations.

Hydrodynamic model of the Svitava and Svratka rivers in Brno
Račoch, Tomáš ; Golík,, Pavel (referee) ; Dráb, Aleš (advisor)
The Master‘s thesis deals with the assessment of the current state of flood protection in the rivers and floodplains of Svitava (km 0.000 - 2,050) and Svratka (km 26,370 - 33,963) in Brno. Using a combined 1D and 2D numerical model of water flow, hydraulic calculations of the peak flows of Q5, Q20 and Q100 were performed. For calculation, HEC-RAS 5.0.6 was used. The outputs were processed in the form of flood hazard maps and drawing documentation.

Assessment of runoff conditions on flow in the Morava river basin
Holá, Lucie ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the design of nature close to the flood protection of the city Prostějov at the confluence of the watercourses Romže and Hloučely and the flow Valova (Romže). In canculations there was solved capacity of individual sections and canculation of levels for one-year, five-year and twenty-year flow. For canculations there was used one-dimensional mathematical model HEC-RAS 5.0.3. Determination of roughness of bottom and slopes was based on personal visit. The result of this diploma thesis is evaluation of current state and proposal of a nature close to the flood protection in the individual streams in the city Prostějov. The thesis contains the calculation part and the drawing part documenting the proposed measure.

River regulation with regard to the flood protection and revitalization
Bohatý, Martin ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
This bachelor thesis focuses on the evaluation of the current state and proposal of the river Bobrava, which can be found in the district of Brno-venkov. Among other things, it flows through the municipality of Želešice, our locality of interest. The work is divided into theoretical and practical parts. The theoretical part is devoted to water flow in an open channel and basic calculation methods. The practical part describes the site of interest, including hydraulic calculations in the HEC-RAS program and the proposed treatment itself. Hydraulic verification of the design and its evaluation is also an integral part of the work.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

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.

River regulation with flood protection
Zvolánek, Radim ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This work describes the assessment of the capacity of the river Chrudimka on the river kilometers 87,837 to 93,173. The hydraulic computation was done for flow with periodicity of 10, 50 and 100. The calculation in the HEC-RAS program is described. Based on the results, flood protection is proposed. Flood protection is verified by a control hydraulic calculation The results are outlined in the drawing documentation

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.
