Follow-up measures for the water management solution of the Těšetice water reservoir
Žiaček, Tomáš ; Fína, David (referee) ; Starý, Miloš (advisor)
The main aim of the thesis was the liquefaction of Únanovka streamflow under the Těšetice dam with the focus on suitable flood protection of the villages of Těšetice, Bantice and Práče.The thesis evaluates the existing condition of the Únanovka streamflow in the river mileage 1.6593 – 6.4103. Calculation of the streamflow capacity was carried out per 1D mathematical model in the HEC-RAS programme for the selected N-year flow from the ČHMÚ hydrological study. Final value of the improved drainage from the dam was determined together with the possible value of water collection. Within the thesis the hydro-ecological monitoring of the watercourse was carried out (HEM analysis 2014).

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.

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.

Assessment of the water flow in the Odra river basin
Mláděnka, Jakub ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The aim of the bachelor thesis is to describe and evaluate in detail the current state of the Luha river and the objects connected with it, in the interest section – river kilometer 0.000-2.853 in the cadastral area of the Jeseník nad Odrou. Part of the work is to assess the capacity of the river flow in the locality and to propose ideological measures that would increase it to the design value of the 20-year flow. 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, the assessment of the capacity of the channel and the objects in the solved section, two variants of continuous river basin adjustment are proposed to improve the current state of the channel and to increase the flood protection of the neighboring area.

Assessment of the water flow in the Morava river basin
Cetkovská, Lucie ; Juráňová, Barbora (referee) ; Uhmannová, Hana (advisor)
The bachelor thesis is focused on the assessment of a part of the stream Romže which is managed by the Povodí Moravy, s. p. The Romže is located in the urban area of the village Držovice. There is a defined area with a potentially significant flood risk. The description of the current condition of the river part is based on the inspection and background materials. The calculations for assessment of channel capacity and the capacity of objects in the location were made by the 1D program HEC-RAS. The individual cross-sections and the N-year flow of the river were put in the program. Based on these results, near-natural flood protection measures for designed channel capacity of the river have been designed.

Design of boulder chute reconstruction in Lomná river at km 1,9
Hrabovský, Michal ; Golík,, Pavel (referee) ; Zachoval, Zbyněk (advisor)
The thesis deals the assessment of the resistance of the existing boulder chute in the river Lomná. At km 1,9 Boulder chute is located in the village Jablunkov. Surface resistance of boulder chute is assessed newly on the basis of non-dimensional shear stress for particle on arbitrarily sloped bed. The calculation of 2D flow was computed by HEC-RAS. On the assessment of resistance was proposed reconstruction of boulder chute.

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 the River Regulation Jihlavka in Jihlava
Salingerová, Lucie ; Šlezingr, Miloslav (referee) ; Uhmannová, Hana (advisor)
The aim of my bachelor´s thesis is the assessment of the Jihlavka River within the boundaries in the town of Jihlava after 11 years, since a renovation flow. The bachelor´s thesis evaluates the current state of the watercourse Jihlavka in the administrative territory of the town of Jihlava from the perspective of the assessment of fortifications of the streambed and the existing capacity of the watercourse. 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. A part of my thesis is a draft of measures to improve the current state of the channel as well as assessing opportunities to increase flood protection of the adjacent territory.
