Feasibility study of the flood protection measures
Charvát, Jan ; Duchan, David (referee) ; Dráb, Aleš (advisor)
This bachelor‘s thesis deals with the assessment and design of flood control measures in the area of Dolní loučky. It uses a combined 1D and 2D numerical model of water flow to perform hydraulic calculations of flood flows passing interest location. Several variants of the calculations for different size heads of n-year floods. Hydraulic calculations were made for water flow Bobrůvka, Libochůvky and Loucky. The results are processed in the form of inundation maps and longitudinal profiles of these flows.

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.

The activities of flood protection authorities of the administrative district of Týn nad Vltavou performed in connection with flood protection measures.
HLAVÁČ, Roman
At the beginning of my thesis, the risk of floods in the territory of the Czech Republic is generally characterized which is followed by basic legal documents governing flood protection. The characteristics of the territory on which this thesis focuses is presented in the next section, which is describes in detail the administrative district of the municipality with extended powers (MEP) of Týn nad Vltavou, the basic description of its hydrological basin and waterways and, of course, the flood profile of the individual municipalities. The following section explains the term of flood, classification of floods and a detailed description of flood risks within detail the administrative district of the MEP of Týn nad Vltavou emphasizing the risk of formation a special flood. This is followed a list of complex activities and measures aimed at preventing and eliminating the threats to the health, lives and property of the citizens, society and the environment during floods. It also discusses planning in the field of flood protection and the classification of flood plans. Emphasis is placed on the documentation of flood protection of the administrative district of the MEP of Týn nad Vltavou that is associated with the activities of flood protection authorities. The section discusses in detail their activities during floods as well as when there are no floods. The function of flood committee of the MEP Týn nad Vltavou is mentioned detailing the description of activities of its individual members. The objectives of this thesis were aimed at finding out about the level of prepared flood protection documentation processed, analysing the activities of flood protection authorities and examining their knowledge about the issue of flooding. All the objectives were directed to the administrative district of the MEP Týn nad Vltavou and its flood protection authorities. Through a sociological survey among the flood protection authorities of the administrative district of the MEP Týn nad Vltavou that was conducted in the form of an anonymous questionnaire testing their knowledge in the field of flood protection. The results obtained were subjected to statistical evaluation, which, together with graphical representation, is of part of the thesis.
