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.

Interaction of groundwater and surface water under extreme hydrological conditions in the floodplain of the upper Lužnice river
Fialová, Petra ; Janský, Bohumír (advisor) ; Šobr, Miroslav (referee)
The object of this work is an analysis of the influence of extreme hydrological events (floods and droughts) in terms of interaction between groundwater and surface water in the river floodplain. The aim of this thesis is also the evaluation of the hydrological regime of the upper Lužnice basin and evidence of retention potential preserved natural floodplain. The selected objectives of the work were resolved on the basis of the values of groundwater levels and surface water in the area of interest. Based on data from underground wells and a digital terrain model, it was possible to create an image of the distribution of groundwater levels in river floodplains during selected hydrological situations. Data from surface flow was obtained from several habitats in the flow direction Lužnice. This has enabled graphically illustrate individual flood waves and characterize their size, speed and transformation after the passage of a preserved natural floodplain of Lužnice river. Carried out research has been confirmed retention capacity of the floodplain, which is most significant at flow rates slightly in excess of the flow capacity of the river bed. However, extreme floods or in periods with many culminations in a relatively short time leads to reduces water retention capability of the floodplain. In...

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...

Hunting behaviour of the wild population of river otter (Lutra lutra) in conditions of the shallow river.
POJEROVÁ, Lucie
Eurasian otter belongs to the group of endangered species. Its decrease was caused by the decline of suitable biotopes and the pollution of waste water. The human activity is considered to be another important reason for its decrease. Eurasian otters were hunted for their fur and for the losses on fish population. Although the number of Eurasian otter has been increasing lately, it is still important to protect these carnivorous animals. This bachelor thesis deals with the issue of foraging behaviour of the wild population of Eurasian otter. The aim of the thesis is to demonstrate the problems of otter?s foraging behaviour in shallow river; mainly the technique of this type of hunting. It was found that in the shallow river of the Lužnice River, the otters prefer rather the hunt-type of ?patch fishing?, which is usual while hunting in deep water. This kind of hunt has different characteristic since the preys are fish which are active during the daytime, contrary to inactive preys known from deep water of lakes and sea coasts. In the Lužnice River there were observed male and female otters and juvenile individuals. There was also observed the number of diving sessions during hunting session, the number of dives and hunting success set by the number of successful diving sessions.
