Revitalization of the selected section of the River
Bakala, Filip ; Petr, Pelikán (referee) ; Šlezingr, Miloslav (advisor)
This thesis deals with revitalization of the selected part of river Drevnice. Main scopes of the work are proposals of fish passages through migration barriers. The work is conceived on four levels. The first of them is dealing with the general characteristics of selected segment and with description of objects on watercourse. The second level is dealing with revitalization, where the basic information about migration and efficiency of fishes are described. In this chapter basic distribution of fish ladders is included. In third part, which is the most comprehensive, I design a boulder fish ramp and bypass channel. The last chapter contains drawings documentation of watercourse Drevnice and my own proposed revitalization elements.

Study of fish-passing facility on the weirs on Bečva river
Chovancová, Kateřina ; Veselý, David (referee) ; Milerski, Rudolf (advisor)
This master's thesis consists of three main parts. The first section describes some types of fish crossings and basic information of their design. There is also marginally described program HEC-RAS. The second part is about the Zuberská weir and Osek stage. I review here fish ladders according to the original drawings in the HEC-RAS and suggest possible options to address these passable fish crossings for the fish crew. The last section is devoted to Mikulenkov weir where the fish crossing has been completely removed. Here I propose a new fish ramp according to modern knowledge and applicable standards. I also review the proposed fish ramp in the HEC-RAS program in order to verify the hydraulic characteristics.

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.

Assessment of the Options of Increased the Flood Protection
Adam, Karel ; Golík,, Pavel (referee) ; Uhmannová, Hana (advisor)
The work deals with the assessment of the stream Chribska Kamenice current state in the village Vsemily urban area. The aim of the project is the assessment of capacity and the current state of the stream-bed. Based on an assessment measure there has been designed the improvement suggestion of the current state and flood protection increasing in close neighbourhood.

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.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

Regulation of River
Šmídová, Hana ; Gernešová, Lenka (referee) ; Šlezingr, Miloslav (advisor)
The aim of this thesis is to evaluate the current status and subsequent design modifications watercourse Olešnice in the cadastral area Žeravice, township Prerov, Olomouc Region. Solved segment located in ř.km.7,226-7,800. The work is divided into several parts. The first part describes the general characteristics of the selected section. The second part examined the flow capacity of the original channel and propose new river regulation. Calculations of flow capacity were performed using HEC-RAS 4.1.0. The third part is to assess the current state of vegetation and riparian vegetation proposal. The last part is the design documentation of the current status and the draft regulation.

Assessment of the capacity of a small watercourse
Kammermayer, Jan ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
The bachelor thesis deals with assessment of the current state of the fortifications in the river Kuřimka from km 5.046 to 6.261, located in the village of Moravské Knínice and identifying existing flow capacity, using program HEC – RAS. It was made a proposal to improve the current state of flood protection and measures. The proposal will improve flood protection of built-up area.

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.
