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.

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.

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 of small earth dam
Stoklas, Jan ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subjekt of this bachelor thesis is the study of a small water reservoir in a particular locality. It consists of a text part and a drawing part. The text part contains brief summary of the issues of small water reservoirs, description of the locality, determination of design flow, needed hydrotecchnical calculations and design of expected technical solution. The drawings show the design of the dam, the combinated funtional object and the modified flooded area.

Flood protection of the municipality Brantice
Zahradníková, Lenka ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with the design of a flood protection for the Brantice municipality, a part of which is an adjustment of the Opava river stream bed, specifically kilometer 77,6554 to 78,7020 and, moreover, a design of a reconstruction of the weir at kilometer 78,340. A capacity assessment of the original stream bed in the built-up area and its surroundings is a part of the thesis, as well as a measure to increase the stream capacity and a design of a boulder chute with a water gate, which replaced the original weir. The program HEC-RAS 4.1.0. was used for the stream capacity calculations.

Proposal of measures on Svratka river in the cadastral area of Svratka
Černý, David ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The diploma thesis focuses on the assessment of the current state of the Svratka watercourse and of the capacity of the existing objects on the course, which is partially modified in the solved locality and includes both – intravarian and extravarian areas of the town. Within hydrotechnical calculations, the 1D mathematical model HEC-RAS version 5.0.6 was used to determine the course of levels. The thesis focuses also on suitable design of flood protection measures on the river Svratka with protection for design flow Qn = Q20 = 28,6 m3 / s.

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.

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.

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.
