Analysis of flood situation on selected part of river
Štěpánová, Markéta ; Smelík, Lukáš (referee) ; Duchan, David (advisor)
The thesis deals with an evaluation of flood situation at the area of the river Svitava in Brno throughout three different flows Q5, Q20 a Q100 and that proposes a possible solution for flood protection. Current state of the river stream is evaluated through hydraulic calculation combining 1D and 2D numerical modelling of flow rate with the use of HEC-RAS software.

Application of Civil 3D to river regulation
Rajnoch, Dalibor ; Špano, Miroslav (referee) ; Duchan, David (advisor)
The goal with this bachelor thesis is to review and modify the watercourse of Moravská Dyje river, in the part from 263,69 to 265,13 km. The modification and revision was made in the Autocad CIVIL 3D program, the computitanon part in the HEC-RAS program. First, the current situation was evaluated, then a plan of anti-flooding measure for Q100-years water was designed. Finally, the suitability of the Autocad CIVIL 3D program in connection with making river regulations was evaluated.

Revitalization of weir on Svratka river inVranovice with fish crossing
Jágr, Josef ; Veselý, David (referee) ; Milerski, Rudolf (advisor)
This present work deals with the design of revitalization measures for the weir in Uherčice (Vranovice) on the river Svratka. The current condition of weir constuction does not allow aquatic animals to migrate, weir constuction is transverse barrier. In this river section are found many fish species like barbel, vimba, nase and chub, for which is migration completely natural part of their behavior. There is concrete weir with a movable flap and on the right bank is located a small hydroelectric power plant. Close to hydroelectric power plant outlet is mouth of Šatava river. Weir revitalization consists of fish pass construction. Proposed fish pass is located on the right bank of the stream. There is a close-to-nature bypass channel that will ensure a continuity of water flow of already mentioned river Svratka between Věstonice lake and Rajhrad weir. Entrance to the fish pass will use a part of Šatava mount, then will continue in the artificial channel to the upstream part of Svratka river. Fish pass exit cannot breake the function of protective anti-flood embankment of Svratka river, hence there will be used block off construction. During condition of flooding will exist the possibility to shut down proposed fish pass.

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.

Proposal of measures on Hodonínka river
Ondrišík, Ivan ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The content of this bachelor's thesis is focused on assessing the condition of the riverbed of a river Hodonínka, which flows through the built-up area of the village of Olešnice, Křtěnov and the vacant area of the village Crhov. The assessment includes an assessment of the current condition of the riverbed and the condition after adjustments with the proposed flood control measures. The proposed modifications are supposed to ensure the protection of parts of municipalities against twenty years of water Q20 = 16,74 m3/s. The section of interest of the stream is located on the river kilometre 13,018 - 14,638 and extends into three cadastral areas. The mathematical model HEC-RAS 5.0.7 is used for hydro-technical calculations, which works in a 1D environment.

Determination of floodplain in Kyjovka river at km 71 to km 74
Kašpar, Tomáš ; Roušar,, Ladislav (referee) ; Zachoval, Zbyněk (advisor)
The diploma thesis discusses the current status of watercourse Kyjovka and a proposal for appropriate protection measures of the territory. The selected section starts at river-km 71,338 and ends at river-km 74,443. The selected part of the watercourse runs through the town of Koryčany. This thesis examines the selected section of Kyjovka split into two subsections. That allows for detailed presentation of several proposed appropriate measures to be applied at critical spots in the selected subsections. The calculation of the watercourse model and its capacity with the water level progresses for selected N(y.o.) flow rates were processed in HEC-RAS5.0.1. program. Proposed flood protection measures are incorporated in the drawings.

The revitalization project of the selected section of the watercourse
Skřížala, Lukáš ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
Bachelor thesis deals with revitalization in the selected section on the watercourse Ondřejnice. Purpose of the revitalization is especially the removal of the migration obstacles creating conditions for the natural development of the trough, without any need of standard maintenance by the flow manager. In the bachelor thesis have been replaced some stone steps by the boulder slip, the wooden gradients have been replaced by some new wooden steps with holes for the migration of animals. Then were in the watercourse designed some Fish shelters. At the places where the gradient adjustment will take place, will be designed a new vegetation accompaniment. By the design of the revitalization measures there will be no worsening of the drainage ratios.

Design of river stabilization structures at the Bečva river in OSek
Lokajová, Hana ; ing. Zedníček (referee) ; Julínek, Tomáš (advisor)
This bachelor thesis is dedicated to the solution of channel recessing in Osek nad Bečvou. One part deals with the evaluation of historical perspective of the area of interest. In the next part of this thesis the transport of sediments is described. The following part contains of an evaluation of current state of the selected part of the river Bečva and deals with a regulation of the river. In the end the theoretical suggestion of protective measure is developed.

Proposal of river training of a small watercourse in the basin of the Morava
Mlčochová, Zuzana ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with an appraisal of capacity of channel and design of suitable measures for environmental protection. Solved segment is located in the channel of Český potok in RK 0,000 – 6,366. The channel is flowing through villages of Čelechovice na Hané, Smržice a Držovice in solved segment. Within own solution the locality was divided into three partial sections, which is enabling clearer description of the proposed measures. Flood measures are proposed in several variants for each partial section. Calculations of flow capacity and water surface for the selected N-year flows were performed by using the program of HEC - RAS 4.1.0. Proposed solutions to flood measures are processed in the drawings documentation.
