The effect of floods on the ichthyofauna of Štěpánovský stream
Čech, Martin ; Čech, P.
The effect of floods on the ichthyofauna of Štěpánovský stream (left-hand affluent of Sázava River, aver. summer flow rate 0.2 m3s-1) was studied using diet analysis of kingfisher A. atthis preying exclusively on local fish community. The first local flood event (2 August 2001; flow rate 100 m3s-1) caused drastic shift in the ichthyofauna composition from original fish community dominated by brown trout S. trutta, brook trout S. fontinalis and bullhead C. gobio to fish community dominated by bleak A. alburnus, roach R. rutilus, chub L. cephalus and gudgeon G. gobio. The second flood event (all Czech Republic floods in August 2002; flow rate 4 m3s-1) was surprisingly much less destructive to fish fauna. Consequently, the stream played also the role of refuge for many new fish species including juveniles of nase C. nasus, vimba bream V. vimba, barbel B. barbus, asp A. aspius and sunbleak L. delineatus, from highly flooded Sázava River.

Experimentální výzkum spolehlivosti těsnění kabelových prostupů v Pražském metru po povodních v létě 2002
Jíra, J. ; Jírová, Jitka ; Bouška, P. ; Vokáč, M.
Confluence of the rivers Berounka and Sázava and outflows from the Vltava dam cascade caused the flow in the lower part of the river Vltava in Prague. The Vltava culminated in Prague on 14 August with a flow of 5160 m3.s-1; this corresponds to a period of recurrence of 500 years. The extension of floods in the Vltava valley in Prague caused penetration of water into underground spaces of the Metro and water flooded 19 of 53 underground stations. Looseness of cable bushings through pressure interfaces and non-closure of some pressure interfaces were the most important cause of spreading of water in underground spaces. After the floods of August 2002 the accredited laboratory CTU in Prague, Klokner Institute designed a methodology of experiments and testing system and performed tests on reliability of cable bushings and on material properties of the U 5000. Results of experiments lead to the recommendation to replace all the existing cable bushing in Prague Metro

The Importance of Public Gatherings in Critical Events: Application to Case of Karlín Borough after Floods in 2002
Holíková, Veronika ; Toth, Petr (advisor) ; Melichárek, Josef (referee)
This bachelor work deals with the phenomenon of the public gatherings of money as one possible source of financing the damages caused by floods. The aim was to answer these questions: why today's society still needs a public gathering, in what may the non-profit sector "compete" with the public sector, and what are the pros and cons of financing flood damages by the public gatherings. There were compared particularly the quickness of reaction and the amount of financial aid of the public and nonprofit sectors. The basis for the answers consists of results of the research, held among the subjects, involved in organizing the gatherings after the floods of 2002. For subsequent data processing was used a special methodology, developed for this purpose of public gatherings, built on existing methods of evaluating the performance of nonprofit organizations.

Šteidlová, Alena ; Ducháčková, Eva (advisor) ; Daňhel, Jaroslav (referee)
The thesis deals with coverage of natural disaster damages by commercial insurance. A description of natural disasters and their possible occurrence mainly in our territory in association with climate changes as the factor causing increase in their number serve as an introduction. Starting from the impact on the world and the Czech insurance sector, where the thesis deals especially with floods in 1997 and 2002, it is getting on to the analysis of the offers presented by three largest Czech insurance companies. The analysis studies the floods in 1997 and 2002 in perspective with different high-risk flood areas specified in our country. The conclusion of the thesis proposes the ways describing how to deal with risks differently, without using the insurance. The proposal advises an insurer to use such methods as reinsurance or alternative risk transfer instruments.

The thesis is primarily divided into a theoretical part, generally dealing with voluntary work as a significant and an indispensable element of the society and also with emergency events in particular the floods which affected the Czech Republic and which without the notable and distinctive voluntary aid could not have been coped with. The practical chapters are devoted to certain chosen aspects of the management of voluntary aid and focus on their specifics during the crises and character of concrete activities non-profit organisations which have taken a considerable part in coping with the recent floods over the last few years. The pivotal chapter of the thesis is the empirical research whose objective was the detection of single aspects of the volunteers' work and the management of voluntary aid during the floods in the Czech Republic. The adopted technique in collecting the data is the standardized questionnaires designed for two groups of volunteers and voluntary fire brigades, which are included in the appendixes of the thesis. The research has showed that there are certain drawbacks and deficiency in managing voluntary aid. Conclusion: The thesis proposes certain recommendations to improve the situation.
