Design of flood protection
Rajnoch, Dalibor ; Smelík, Lukáš (referee) ; Duchan, David (advisor)
The diploma thesis copes with the evaluation of status quo and further proposal for a flood control arrangements for the river Dřevnice (Zlín district). The evaluation as such has been made by the hydraulic calculation of flow alongside 2D numeric model - SMS-TUFLOW software was used for these calculations and sub-calculations. Based on the results as evaluated by numerical model, the proposal for a flood control arrangements has been made and is further available within the document. Last not least, the utilization of the aforementioned arrangements was measured and described.

Hydraulic analysis of the Bečva river
Gřegoř, Adam ; Smelík, Lukáš (referee) ; Duchan, David (advisor)
The subject of this diploma thesis is a comparison between two river hydraulics modeling approaches, the first one being combined 1D and 2D modeling, and the second one being solely 2D modeling. Both models are located at Bečva river, between its 17,282 and 28,419 river kilometer. The outputs of the simulations are water flow velocity maps, water depth maps, maps that show differences between flood areas calculated in both models, tables comparing channel water surface elevations and schematic long sections. In conclusion of the thesis, the outputs of the simulations are compared.

Design of flood protection measures or revitalisation at the selected site
Ondrišík, Ivan ; Smelík, Lukáš (referee) ; Duchan, David (advisor)
The content of this diploma thesis is focused on hydraulic assessment of the river Dřevnice, which flows through the village Otrokovice, Tečovice and Zlín. The assessment includes assessment of the current condition of the riverbed its surroundings and the condition after adjusments with the proposed flood control measures. Those flood control measures and modifications are supposed to ensure the protection of parts of municipalities from unwanted water spills at a flow rate of Q100 = 327,00 m3/s. The section of interest of the river Dřevnice stream is located on the river kilometre 2,358 – 9,050 nad its total length is 6,692 km. As part of hydrotechnical calculations, the mathematical model HEC-RAS 6.3.1 is used in this diploma thesis.

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 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.

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.
