Assessment of the River Regulation in the Basin of the Odra River
Urbánková, Olga ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The thesis deals with the assessment of the river Odra regulation in the river kilometer 88,199 – 80,076 in the urban area of Loučky nad Odrou. The thesis is focused on an assessment of the condition and fortification of the riverbed, vegetative components, the capacity and the flood protection. The assessment is based on a 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 and its capacity; according to these draft measures were designed. The thesis can result in a benefit in the future when designing flood protection schemes in this problematic area.

Feasibility study of the flood protection measures
Šťastová, Barbora ; Špano, Miroslav (referee) ; Dráb, Aleš (advisor)
The aim of bachelor thesis is feasibility study of the flood protection measures in Komin on Svratka river. Construction is divided by two building objects: ironconcrete small wall and sprinkled dike. That protection is constructed for peak flow Q100 and not influenced by safety elevation of 0,3 m. The output of work are drawings of construction and photodocumentation depicting the current status of the territory.

Study of possibilities protection against rural zone water
Skolková, Daniela ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This thesis is divided into two parts. The first part of thesis deals with the problems of soil erosion, surface runoff and measures affecting runoff. The part also explains the concept of surface runoff, and what are the most common methods taken to avoid water erosion caused by surface runoff. The next part about measures is divided into two chapters. The first part of measures describes the most common measures to increase the infiltration of surface runoff. In the second part of these measures were been described the measures to support water retention. The second part of the thesis includes methods of flood protection municipality Sebranice.

Experimental verification of flood kidney three bag functionality
Požárová, Miroslava ; Dráb, Aleš (referee) ; Žoužela, Michal (advisor)
This bachelor's thesis deals with the system of large-volume flood bags Protex - K manufactured by the company KOEXPRO OSTRAVA, joint stock company. The bags consist of polyethylene fabric filled with cement and fly ash mixture. The system enables creation of many shape modifications. One of them is the so-called triplet formed from three hose bags with the nominal diameter of 300 mm. The goal of the work was to verify functionality of this bag in one of the hydraulic troughs in the Laboratory of Water Management Research of Department of Water Structures of the Faculty of Civil Engineering, Brno University of Technology. To assess the functionality, the bag stability was tested with various water levels, and discharge coefficient and specific leakage per one standard meter of the bag was determined. The resulting discharge coefficient was compared with discharge coefficients of similarly shaped constructions. The work includes comparison of the flood bags with commonly used bags. Furthermore, the data obtained by measuring and processed in the tabular and graphical form are presented in the work.

Study of possibilities protection against rural zone water
Hyžák, Aleš ; Ing.Radka Roubcová (referee) ; Milerski, Rudolf (advisor)
This bachelor thesis deals with the problem of soil erosion, surface runoff and its subsequent influence on the situation in affected areas. It also addresses the technical measures proposed in the watershed affecting surface runoff. The scope of work can be content to divide into three parts. The first one deals with soil erosion vulnerability and describes surface runoff. The second section describes the most common technical measures implemented and their impact on surface runoff. Part three contains a specific problem solving situation in the Sněžné village.

Flood protection and reducing of flood damages in intensive agriculturally used landscape
KULHÁNEK, Pavel
The aim of this study was to analyze the Bechyňský stream with regard to the possible consequences of floods in this area. Furthermore, the removal of these consequences and propose new flood protection measures and recommendations. Finally, the work is a summary of the most suitable variant of flood protection. The work may help in future decision how to manage the flow of the Bechyňský stream and surroundings of it´s.

Game theory in the current flood protection
Pokorná, Veronika ; Macháč, Jan (advisor) ; Louda, Jiří (referee)
In recent years a considerable attention has been devoted to flood protection measures because of great damages caused by floods. While planning measures the consideration is based on costs and benefits associated with their implementation, i.e. the application of cost-benefit analysis (CBA). In most cases the relation of upstream and downstream in river catchments is neglected, therefore in the practice a potential for a retention of upstream remains unused. This bachelor thesis deals with a projection of this upstream/downstream relation into the current flood protection. Mathematic method of the game theory is used for the analysis of the optimal allocation of flood protection measures between the upstream/downstream areas. The upstream/downstream relation is defined by the specific assumptions and conditions. On the basis of these specific assumptions and conditions a payoff 2x2 matrix is modelled. The thesis constructs individual scenarios of mutual positions of these two parts. Possible outcomes are analysed by using game theory, while taking into account liability for damages, negotiation options and transaction costs. Presented results of individual scenarios indicate that the game theory is a suitable tool for the assessment of an optimal allocation of flood protection measures and its application in practice is appropriate in conjunction with other tools.

Vodní prvky v krajině
Petruchová, Jana
This paper discusses the sources of water in the landscape, divides water features according to various methodologies and describes their nature and functions. It also deals primarily with the development of water loss from the landscape in our country and shows the history and problems of regulating rivers. It points out the consequences of these activities, discusses the historical and current measures - restoration and renaturation of watercourses and the return water back into the landscape. It also discusses the historical development of the country with regard to the aquatic. The case study deals with a model water feature - Bečva river from the source to the mouth. It describes interesting gravel flow. It analyzes the problematic sections of the river and above all the consequences that left a flood in 1997, when there was a change in the morphology of the river bed. At these new locations carried successional development of plant communities and soil creates a new profile. The author's thesis deals with these sites, especially ripping shores and gravel benches on Bečva in Osek. The paper describes the concept of river flood protection of the Bečva river, technical proposals and revitalization . The author evaluates these studies. It also shows the differences regulated and refolded channel.

Flood protection in urbanized landscape
NEUBAUER, David
This thesis deals with the problems associated with floods and various kinds of protective measures. These measures should help to reduce the damage caused by floods and protect people on their health and lives. The work includes theoretical and practical part. The reader will find the theoretical concepts associated with floods and flood control measures, which are described individually. The practical part contains one selected area which is characterized in detail. The list of references from which it was drawn is given in the final park of work. The work also includes photographs of the selected river basins and map outputs for a better idea of the selected location.
