Splaveninová study of a selected flow
Zouhar, Radim ; Maleňák,, Jaroslav (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis focuses on determination of sediments amount in Svitava river and Křtinský potok, which flows into Svitava river in Adamov. Elements are sedimented at the riverbed bottom if the resulting force caused by the water stream on particles is smaller than the gravitational force. Elements can get into the stream both by washing from surrounding terrain and by material erosion of the riverbed which happens more frequently. Therefore another part of this thesis is suggesting of suitable stabilization measures and flood protection of selected objects. The capacity of riverbeds becomes smaller due to their sedimentation. Particle-size characteristics of sediment runoffs have been prepared and thus the amount of sediment runoffs has been calculated and critically evaluated.

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.

Revitalization of the selected section of river "Hartmanický potok"
Samková, Aneta ; Gernešová, Lenka (referee) ; Šlezingr, Miloslav (advisor)
Diploma thesis deal with revitalization Hartmanice river in district Svitavy. Section of interest is on 0,400 – 1,234 of river km. Part of this thesis is also rating current condition of stream and his vegetation accompaniment. Rating was made on base of reconnaissance terrain, my own measurement and photo documentation. In diploma thesis was design some revitalization steps: stabilization sink with wooden sills and stabilization slopes by using willow fences and similar precautions. There was designed total change of flow trend. Rating of current condition and condition of modified stream was made in software HEC-RAS.

Evaluation of Flood Protection of Brumov-Bylnice
Man, Radim ; Zábrana, Martin (referee) ; Jandora, Jan (advisor)
The aim of this bachelor thesis is the assessment of the flood protection of city Brumov-Bylnice on the Brumovka river and subsequential design of eventual new flood protection. The HEC-RAS program will be used to calculate the capacity of the channel. At the end of this bachelor thesis the technical solution of flood protection will be described.

Study of river restoration measures of suburban watercourse
Šebesta, Radek ; Veselá, Olga (referee) ; Králová, Helena (advisor)
This diploma thesis deals with the problem of river restoration. Selected watercourse, which was inappropriately technically modified, had been mapped in detail and land use map was compiled. The watercourse was divided into sections, which were described in detail and assessed for suitability for restoration action. The new nature-friendly channel was designed on the selected section of the watercourse. Technical graphic documentation was designed.

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.

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.
