Berka, Ondřej ; Zachoval, Zbyněk (referee) ; Veselý, Jaroslav (advisor)
Bachalor's thesis „Study of Sediment Transport, Flood Protection and Outline of Flood Plan in Chosen Part of the River Thaya“ is divided into four parts. In the first one, I describe chosen part of the river Thaya from the Nové Mlýny to the Břeclav weir with focus on geographic, geological and hydrogeological conditions, hydrotechnical structures and river adjustments, biota and protected areas, demography and Lednice-Valtice Cultural Landscape. In the second part, I determine, by bed load samples granulometric analysis, the source of sediments, which appeard under the Břeclav weir. In the third part, I describe chosen area from the view of flood protection, I describe historical floods and I assess capacity of chosen problematic profiles using HEC-RAS program. In the last part, I focus on flood protection of the village Lednice and of the part of Lednice-Valtice Cultural Landscape, I describe problems of this area in context of flood protection and I suggest outline of the Flood Plan of the Village Lednice.

Splaveninová study of a selected flow
Zouhar, Radim ; Maleňák,, Jaroslav (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis focuses on determination of sediments amount in Svitava river and Křtinský potok, which flows into Svitava river in Adamov. Elements are sedimented at the riverbed bottom if the resulting force caused by the water stream on particles is smaller than the gravitational force. Elements can get into the stream both by washing from surrounding terrain and by material erosion of the riverbed which happens more frequently. Therefore another part of this thesis is suggesting of suitable stabilization measures and flood protection of selected objects. The capacity of riverbeds becomes smaller due to their sedimentation. Particle-size characteristics of sediment runoffs have been prepared and thus the amount of sediment runoffs has been calculated and critically evaluated.

Scope and impact of floods in the river basin Polečnice
MAXA, Václav
The preparation of the bachelor thesis includes the collection of information on the issue, especially the theoretical part focuses on the study of legislation and the use of Internet resources. The aim of the author in the theoretical part is to explain important concepts in the field of flood and related topics. The individual chapters focus, for example, on the flow of the Polečnice river, types of floods in our country, levels of flood activity, legislation in the field of floods, as well as preparations for floods and warning the population. The practical part contains a description of the Český Krumlov district and the floodplain of the Polečnice river, then the two biggest modern floods in our country are described, namely the devastating floods of 2002 and 2013. Furthermore, the modification of the riverbed of the Polečnice river, which served to create the necessary flood protection measures on the Polečnice river. And last but not least, a questionnaire survey. In the questionnaire survey 100 sheets with 12 questions were evaluated. The questions focused on the general overview of the citizens of Český Krumlov about the flood issue and their awareness of situations caused by floods, such as protection of health, lives and property, related warnings to the population and their evacuation. And whether they are aware of the threat of danger from the Polečnice river, which at first glance may not seem dangerous at all. The evaluated data indicate that the inhabitants of Český Krumlov rather underestimate the risk of floods in the town of Český Krumlov. Some inhabitants do not even know that partial flood protection measures have been carried out on the Polečnice in the recent past. The only positive thing I see is that nowadays, thanks to the technology we have, citizens have the opportunity to get information about the situation quickly and thus be better and more quickly prepared for a possible emergency.

The activity of the integrated rescue system during floods in a village with extended powers
DUŠKOVÁ, Denisa
The main topic of the bachelor's thesis is the floods in 2002 and 2013 in the entire affected area of the Czech Republic and also in the village with extended powers of Vodňany. The activities of the relevant authorities and the population were evaluated, focusing on the extent of the evacuation and the progress of the basic and other components of the integrated rescue system. The theoretical part begins by defining important legislation for this topic, which is a basic pillar here. Furthermore, this section contains a description of the integrated rescue system, flood authorities and individual measures before and during the flood. There is also a simple explanation of the term "evacuation" and the last chapters of the theoretical part include the floods in 2002, 2013 and the flood situation in Europe in 2021, because in each country the intensity of floods, their consequences, course, but also the progress of rescue services and the attitude of the population varies more or less. The scenario is not always the same, and it is important to know how other countries will deal with a living disaster of this magnitude. The practical part focused on a detailed description of the content of the Digital Flood Plan of the town of Vodňany, a breakdown and assessment of the activities of the authorities and the integrated rescue system during the floods in 2002 and 2013 in Vodňany and finding out the knowledge and preparedness of the Vodňany population on the topic of floods. The results of this survey were developed into graphs. Based on the acquired knowledge, it can be stated that there are obvious shortcomings in the knowledge of the citizens of Vodňany on the topic of floods.

Flood protection and flood plans on selected basin of the Lužnice river
KUKAČKOVÁ, Lucie
The thesis consists of two parts - the theoretical outline and the research. The theoretical section describes in general the topic of floods, protection of the population against floods, flood control measures, flood plans and legislation related to floods. The last chapter of the theoretical section is focused specifically on the Lužnice river and the affected municipalities, in which qualitative research took place. These are the villages of Vlkov, Veselí nad Lužnicí, Dráchov and Soběslav. In order to fulfil the aim of this thesis, it was necessary to acquire not only flood plans of the affected municipalities, but also other non-public documents, and to thoroughly analyze and compare them with each other. Based on this analysis and comparison, information was compiled concerning flood protection measures in the municipalities, where the investigation took place. This comprehensive information is presented in chapter 'Results'. During the qualitative research, several errors and shortcomings were uncovered in the flood plans of municipalities in the Lužnice river basin. Shortcomings were discovered mainly in the continuity of flood plans and in the absence of endangered objects, which should be listed in flood plans. These objects pose anthropogenic risks to municipalities. Others shortcomings were found in food plans updates. These updates should be performed regulary but this is not happen in practice. For example food plan of the village Vlkov is 22 years old and has been update only once. During the examination of the official websites of the municipalities, other shortcomings were found in the information available to the population. The actual investigation and analysis of the flood plans provided an answer to the research question. Individual flood plans and flood control measures are not in concord.

Assessment of flood control measures to protect the population in selected cities of the South Bohemian Region (the Lužnice basin)
CHLISTOVSKÝ, Miroslav
The Diploma thesis on the theme "Assessment of flood control measures to protect the population in selected communities of the South Bohemia region in the catchment area of the river Lužnice" is divided into theoretical part and the research part. The theoretical part is a general whole, which in the sections refers to the relevant legislation of the flood problems, it explains the flood as the concept and everything associated with it. In particular it introduces the readers with flood characteristics of the territory of the Czech Republic and with the characteristics of the catchment area of the river Lužnice. It describes the selected municipalities by its flow, which are the subject of the research. It explains the difference between a natural and an extraordinary flood, describes the historic and contemporary floods and their damage. It deals with the protection from natural disasters, characterizes the activities of the relevant organs of the protection flood. In the context of the protection of the population it defines the summary measures that help to ensure the protection of life and health of the people, property and environment in emergencies, which are warning, evacuation, hide and emergency survival of the population and other measures to ensure the protection of life, health and property. The aim of this work is to evaluate the effectiveness of flood control measures from the perspective of the number of the protected inhabitants on the territory. In order to achieve the goals, it was necessary to make several consecutive steps. On the basis of assessed results it could be returned to the research question, whether the built flood protection measures are effective in relation to the protected values of the life, health, property and the environment. For the fulfillment of the objectives of the work and verification of research questions,it was need to be familiar with the relevant legislation of the subject, then with the implemented measures, flood protection plans of the municipalities including analysis of their substantive and organisational components. After that to perform the qualitative processing of the survey, the respondents of which were the statutory representatives of the municipalities, who are in charge of the flood protection, and other charged people (e.g. crisis management staff, officers of the Department of the environment or Building office, etc.). The found facts served to the description, evaluation, comparison and analysis of the flood control measures in relation to the number of the protected inhabitants within the catchment area of the river Lužnice. In this way the concrete results were obtained and discussed in the comments of this Diploma thesis. The submitted Diploma thesis in its research part assesses the effectiveness of the flood control measures in the framework of the protection of the population in the South Bohemia municipalities - Bechyně, Tábor, Planá nad Lužnicí, Soběslav, Dráchov, Veselí nad Lužnicí by the flow of river Lužnice, that touches the ranked in the river kilometres from 10,6 to 77,3 km lines. The inspiration for the processing of this Diploma thesis there were the consequences of disastrous floods in 2002, 2006 and 2013 in these areas, which have caused enormous damage and even loss of life. Then the personal interest of the author, as a resident of the town Veselí nad Lužnicí and respectively the member of the crisis management of this town. The research question and the methodology of the research were designed to be filled the objectives of this thesis, it means the evaluation of the effectiveness of the flood control measures from the perspective of the number of the protected inhabitants on the territory. The thesis evaluated the current status of flood protection, description, comparison and analysis were made. There were designed some of the other possible measures that would, in my opinion, led to the improvement of flood protection...

Studie návrhu povodňového plánu vybraného území - Městská část Brno-sever
Oliva, Tomáš
A flood plan is one of the fundamental documents of flood protection. This thesis deals with the design of flood protection and flood protection plan, which in practice will help to correct coordination of all members involved in flood protection. The first part of the thesis is a literature review, which deals with the general characteristics of floods, their origins, what kinds of floods distinguish the conditions under which they originate and what characterizes them. There is also the issue of flood protection, Integrated Rescue System IZS and the legislation that relates to this. The next section is a brief description of the area. The territory chosen for this work is district Brno-sever. Basic documents and materials for the investigation are provided by this district and subsequently studied. Followed by field researche of flow control's whatch spots and inventory of materials for flood protection control. After reading all the materials of the flood plan of Brno-sever it was found, that some of the data are no longer valid and will need to be modified or supplement. The main problem was the issue of flood commission. Specifically, which representatives should be appointed to this committee, what is expected of them and what are their exact duties. Following these findings I prepared a clear methodology for the flood commission, in which is precisely defined, from which department this man should be and what are his tasks. The conclusion summarizes the importance of a flood protection plan. Flood protection is becoming, along with changing climatic conditions still thornier issue, and despite the fact that Brno was not offten affected by floods in the recent past, the aim should be that all inhabitatns would be prepared for this unpleasant possibility.
