Proposal of deployment profiles optimization concerning premier water levels in the South Bohemian region.
ZÁVODSKÁ, Pavlína
The diploma thesis on "A Proposal to Optimize the Distribution Network of Water Level Gauging Stations in South Bohemian Region? deals with the distribution network of gauging stations of a category ?A?, ?B? and ?C? in the catchment area in South Bohemia. The thesis has been designed as an overview of the current situation of the gauging stations in South Bohemian Region; it is focused on the distribution network of these stations not only in the areas hit with floods. It examines whether these critical places across which the stations have been distributed since 2002 correspond to the requirements of the current flood protection, whether it would not be advisable either to increase or, on contrary, to reduce the number of stations in the exposed river areas. The data processed by Povodí Vltavy, Horní Vltava s.p. Plant, and documents by the ČHMÚ were used for the purposes of this examination. The result of the thesis is the fact that the number of the distributed gauging stations is sufficient as for the needs of flood protection, which has been found out by means of structured interviews with the respective experts. Position of these stations has been incorporated in the flood prevention plans and most of these plans have been designed just on the basis of the distribution network of the gauging stations. The critical locations have been sufficiently mapped and recorded and the flood forecasting and warning service uses the gained, very precious information from these gauging stations. The goal of the thesis was to assess the current distribution network of the gauging stations on the rivers in South Bohemian Region. The current distribution network of the gauging stations on the rivers in South Bohemian Region was studied on the basis of an analysis of the ascertained data and documents. The first goal of the examination was the issue whether the current distribution network and the number of the gauging stations correspond to the needs of protection of citizens, cultural heritage, and property, and whether it would not be advisable to increase the number of these stations. The other goal of the thesis was to optimize the gauging stations with respect to the usefulness and their distribution network, whether the distribution network corresponds to the flood protection. The current distribution network of the gauging stations was analysed by means of a partial method of field research, consulting the expert books, legal regulations and a field research. By analysing these data, I tried to find out in the thesis whether optimisation of the number and the distribution network of the water level gauging stations correspond to the current requirements of the gained data from the respective subject-matter authorities. Upon the results of the analysis of the documents, it was found out that the distribution network and optimization of all gauging stations of all categories - ?A, B, C" - meet the needs of the catchment and requirements to their distribution. Upon the gained information, it was found out that Povodí Vltavy and the operators of the gauging stations have created a very clearly organised network. The hypothesis whether the water level gauging stations are distributed on all of the important rivers in South Bohemian Region was disapproved. The gained information suggests that the gauging stations are distributed on all rivers in South Bohemian Region. The research results have revealed that there is a number of locations in danger of big flooding, however, overflowing at such areas does not put in danger people?s lives, health or property. To conclude, it can be said no matter a society is prepared for flooding as best as possible, the nature, namely water, is an element that is to be respected a lot. This is very important in terms of protection of health, life, cultural heritage and property. The thesis will be offered to the water-management authorities and administrators of the location for further use.

Floods in the South Bohemia Region
HRDÝ, Roman
Floods in the South Bohemia Region The first chapter provides general information including the current legislation of the Czech Republic pertinent to crisis management, floods, crisis situation and crisis state definition, and the categorisation of events/disasters, including flood. The important role of urbanism which affects the course and consequences of floods is also discussed. The second part deals with the issue of floods, their origin, classification, floodprotection measures and forecasting as connected with the Czech Hydrometeorological Institute whose functions and procedures are described. The main part presents results of the field survey carried out in the municipalities affected by floods in the South Bohemia. I describe, compare and analyze the last great floods in the years 1997, 2002 and 2006 in the Czech Republic, or the South Bohemia Region. Their intensity, progress, meteorological reasons and damages which they caused are evaluated. I generalize the factors with a direct influence on the extent of damages, including social and economic impact. In conclusion of this part, the danger of floods in the world is also mentioned. In the final part of my thesis, climatologists{\crq} opinions on global warming and the possible causation of this threat with floods are presented. The result is the confirmation or invalidation of the working hypothesis which I set for my thesis.
