River training of a small watercourse in the Morava River Basin
Filipi, Josef ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The aim of this thesis is to evaluate possible solutions of the river Svratka silting by the historical development from the 70s to the present. Part of this thesis is devoted to assessing the state of the watercourse in the area of interest, the assessment of flow capacity and design parameters that were used for the initial treatment course. The outcome of this thesis is to identify the causes of riverbed silting, creation of a conceptual design modification of the streambed and measures to limit the rate of canal silting. Custom design is supported by the hydrotechnical calculations.

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.

Design of boulder chute reconstruction
Zahradníková, Lenka ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
The aim of the thesis is to design a boulder chute reconstruction for the Rožnovská Bečva watercourse at 10,865 river kilometers. The design proposes adjustments of the watercourse of the total length of 642,8m. The thesis also includes designed parameters for the boulder chute reconstruction at 10,865 river kilometers. The current watercourse capacity was assessed using the HEC-RAS 4.1.0 software and a computational model was made of the parameters of the chute. The capacity of the newly designed riverbed was verified using HEC-RAS 4.1.0. Based on the calculations, the boulder chute reconstruction was designed.

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 the gated weir
Skřička, Jakub ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The Bachelor Thesis deals with the study of the existing uncontrolled weir on the river Svitava in district Brno-Obřany. The first part of the Thesis contains a theoretical part about theme of weirs. In the next part Thesis describes the current state of the area of interest, including the riverbed of Svitavy with neighboring objects. After that the Thesis describes the design of the reconstruction, including the selection of suitable movable construction and procedure of hydrotechnical calculations. In conclusion, a calculation of the stability of the design was described.

Proposal of flood protection on the river in the basin of the Morava
Salingerová, Lucie ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The main aim of the thesis is an appraisal of the stream Oslava which belongs to the Náměšť nad Oslavou region with the focus on flood control of the town. The thesis asseses current state of the stream with respect to the state of riverbed, bulwark of the stream and evaluation of the capacity of the stream channel. Calculation water surface profiles have been made by usage of the 1D mathematical model HEC-RAS for selected N-year flows. The capacity of flows and objects in the given period has been detected. There is also a map of the water runoffs included and possible solutions of how to protect the area surrounding the stream are proposed. The thesis was complemented with hydroecological monitoring of the stream channel - the HEM analysis 2014.

Assessment of runoff conditions on the water flow Luha
Urbánková, Olga ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
Diploma thesis deals with the assessment of runoff conditions on the water flow Luha in the river kilometer 8,120 – 13,900. The river flows in the urban area of Polom and undeveloped area of Polom and Heřmanice. The thesis is focused on an assessment of the condition of the riverbed, capacity of the river and on design of a flood protection. The thesis includes an assessment of the condition of fishponds. The assessment is based on personal visit and photos taken as record. Program HEC-RAS was used to calculate the water levels. The outcome is an evaluation of the river condition according to a method HEM and design of the flood protection.

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.

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.
