Main controls affecting the occurrence and extremity of rain-on-snow events in the Ptačí potok basin in the Šumava Mts.
Paulusová, Barbora ; Jeníček, Michal (advisor) ; Hotový, Ondřej (referee)
Rain-on-snow events (ROS) are natural phenomena that have the potential to cause serious floods, wet avalanches and slushflows. Due to climate change the spatial distribution and intensity of ROS events is changing. Accordingly, ROS events become more frequent in high-elevation areas as well as in high latitudes, whereas their occurrence at low-elevation and low latitudes is less common. The behaviour of a snow coverduringrainfallandmechanismsofrainwaterpropagationthroughthesnowpackarestill poorly understood. A frequency and correlation analysis of ROS events in the Ptačí potok basin in the Šumava Mts. was conducted. The selected characteristics of the events were calculated from measured climate and streamflow data (2015-2019) and then analysed to examine the influence of individual characteristics on the development of ROS events. Results indicate a significant correlation between the amount of precipitation and the resulting outflow, as well as the influence of other snow and rain characteristics was shown. The time lag of outflow was mainly influenced by snow density. In order to evaluate the impact of climate change on ROS events, climate time series were analysed for the period 1961-2017 and a significant increasing trend in winter air temperature and decreasing trend in snow depth were...

Dams in legal relations
Majerák, Pavel ; Franková, Martina (advisor) ; Pokorný, Jiří (referee)
TITLE: Water reservoir in legal relations AUTHOR: Pavel Majerák DEPARTMENT: Department od Environmental Law SUPERVISOR: JUDr. Martina Franková, Ph.D. ABSTRACT: This diploma thesis deals with the analysis of the issues of legal relations of water reservoirs, namely as a specific water work or naturally originated,so called natural body of water. In relation to the absence of legal definition of the term of water reservoir it defines the term of water reservoir itself and it closer introduces its single forms which it subsequently introduces in single legal regulations of public and private law. Special attention is paid to water reservoirs in the concept of protection against the impacts of droughts and in realization of anti-flood arrangements. KEYWORDS: water reservoir, law, water work, flood, drought

Water analysis and combating drought in the Rokytná river basin
Říha, Tomáš ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
This diploma thesis focuses on water management analysis of the Rokytná River and finding suitable precautions usable by municipalities when dealing with drought and lack of water in their administrative district. The short research at the beginning of the thesis summarizes problematic of drought and lack of water in the Czech Republic, including the current state and overall context. Next part focuses on the assessment of current state of the Rokytná River basin, based on performed reconnaissance of the basin and processed analysis of a part of the basin delimited from km 0,0 to km 16,7 of the river, between towns of Ivančice and Moravský Krumlov. This analysis concentrates on finding factors, which can contribute to extent of drought impact in this area. It also contains a suspended load study of the waterway, which writes up granularity characteristics and calculation of the amount of transported material from a suspended load sample, taken from the bed of the Rokytná River. The overview of suitable proceedings and precautions follows, based on findings in previous parts of the diploma thesis. The conclusion of this thesis consists of very suggestion of suitable steps and precautions related to particular localities in the Rokytná River basin. Target is to enhance the retention ability of the region and to minimize the impact of both drought and floods. The result of these actions should be the empowerment of environmental sustainability in this particular area. Conclusions of this thesis can be used by municipalities and other administrative bodies when creating an approach of combating drought and when deciding about the implementation of relevant precautions.

Legal aspects of water retention in the landscape
Houžvičková, Markéta ; Žákovská, Karolina (advisor) ; Sobotka, Michal (referee)
Legal aspects of water retention in the landscape Abstract This diploma thesis deals with the legal aspects of water retention in the landscape in response to the current problems associated with impaired landscape retention capacity such as drought, erosion or floods. The author first outlines the factual and legal context of the issue, which is followed by an analysis of conceptual, administrative-legal and economic instruments of the Czech legal order that can improve water retention capabilities of the landscape. The diploma thesis analyses the relevant instruments of the Water Act, Forest Act, Act on the protection of agricultural land or Act on protection of nature and landscape. Consequently, it deals with the role of land-use planning, land consolidation and environmental impact assessment for the issue. The thesis includes comprehensive evaluation of the relevant legal regulation in terms of its effectiveness and possible proposals de lege ferenda.

Changes in extremity and seasonality of floods in the Zdobnice River basin
Čermák, Daniel ; Langhammer, Jakub (advisor) ; Šobr, Miroslav (referee)
The object of the bachelor thesis is to analyze the change of extremity and seasonality of floods in the Zdobnice basin. The literary research comprehensively presents floods with description of the biggest historical floods in the Czechia and in the Zdobnice basin. The literary research also includes the physical-geographical characteristic of the studied area. The practical part is based on the daily flow data analysis, obtained from CHMI (Czech Hydrometeorological Institute). Runoff analysis is performed on the base of these data, with focus on extreme flows. To compare the seasonality change, data series is divided into two periods (1945-1969 and 1970-2014), which point of change was determined by Pettit's and Buishand's homogeneity test. Seasonality change is compared by directional statistics, polar graphs, curves of cumulative frequency and flood index. As a result of these methods, it is found that in the second period, the flood risk is greater in earlier parts of the year. It has been also found, that there are more flood events in July. Key words: Floods, discharge, hydrological extremes, historical floods, seasonality, Zdobnice

Possibilities of banks stabilization of Desná watercourse
Lach, Radek ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The thesis includes the assessment of the current state of the Desná watercourse in the cadastral area of Velké Losiny and the subsequent suggestion of the remediation of two solves sites in the solved area.The river falls under the management of Povodí Morava, s.p. and for the most part it flows through built-up area of Maršíkov. To assess the current state of the river bed, a personal tour of the area of interest was conducted, during which everything was digitally documented. To determine the river bed capacity and calculate the progress of individual levels with the inclusion of all existing objects on the flow in the solved section, the 1D program HEC-RAS was used. Level flow calculation was made for one-year, five-year and capacity flow. Based on the literature search, measures were proposed to remediate bank erosion in locality 1 and locality 2. In these locations, an ideological nature-friendly measures in the river bed were proposed.

Epidemiological and ecological impacts of floods in the Cesky Krumlov district
PAPOUŠKOVÁ, Michala
The topic of my diploma thesis are Epidemiological and ecological impacts of floods in the Cesky Krumlov district. In the theoretical part I deal, from the perspective of epidemiology, with infectious diseases that may occur due to floods, I explain what information system was used by the regional hygiene stations in order to carry out the obligatory report, records, and analysis of occurrence of infectious diseases, and I would like to point out that from 1 January 2018 on, a new system started working for regional hygiene stations in the Czech Republic. Further, I deal with ecological impacts, and explain ecology in terms of Nature Conservation Act. Last but not least, I mention floods as such in the theoretical part, I define flood legislation, what administrative authorities work if such a crisis situation occurs, and what flood affected the region of Cesky Krumlov. The practical part analyses Epidat and the ISIN information system data using metaanalysis, searching for a link between them and infectious diseases during floods. I focused on infectious diseases that ma occur in connection to floods, such as Leptospirosis, Shigelosis, Cryptosporidiosis, Gastroenteritis caused by Campylobacteria and Norovirus, Virus Hepatitis type A, and Virus Hepatitis type E. The Discussion part evaluates the questionnaire aimed at the citizens of Cesky Krumlov region, also at the primary school pupils. What is their image of consequences of floods, and what may bet he cause. The results are then discussed in the conclusion of my diploma thesis. Creating an information leaflet meant for the lay public is another output of my diploma thesis.
