The environmental impacts of floods on the territory of South Bohemia was chosen as a topic of a thesis for several fundamental reasons. One main reason is the significance of the landscape and reflect on its values. The landscape is a set of individually occurring scenic features and extensive landscape structures, in which have individual natural compounds their irreplaceable function. Besides landscapes, the floods have a different environmental impact. Since 1997, the occurrence of floods has unexpectedly increased, and therefore the issue is getting more and more attention. Currently, the so-called environmental security is a hot topic, the evidence can be seen in the increase in professional publications and it also gets into the school curricula. Although the thesis focuses on the territory of South Bohemia, the results can be applied for the entire Czech Republic. The final survey includes a total of eight municipalities with extended powers, where interviews were conducted with the employees of the Department of the Environment, the Crisis Management,the Regional Hygiene Station of the South Bohemia, the Vltava River Basin and selected agricultural companies. This thesis titled "The environmental impact of floods in the South Bohemia" aims to evaluate the changes caused by the floods in the affected areas in the South Bohemia a reserach questiion follows: What are the effects of floods in terms of environmental impact in the South Bohemian Region? To achieve the set objectives the method of literature research was used, by which the basic information necessary to understand the issue was described. The method of qualitative research was also used; the reasearch was based on structured interviews with experts in the field. Afterwards, the information were logically organized and evaluated. The thesis is divided into two general parts. The first is a theoretical part, which describes the flood and its categories and its causes. It also explains the factors affecting the flood, the impacts on habitat and the flood retention capacity and its increase. It also describes and compares the largest floods in the Czech Republic since the 19th century, the basic law governing the issue of water and floods, flood protection organization in the Czech Republic and last but not least, the environmental security and the definition of the duties of the Czech Hydrometeorological Institute. The second part describes the effects of floods in terms of the environmental impacts and describes its recourse. The nature needs some changes in order to be varied. That may come in the form of floods, even though after the water decrease its tremendous power and devastating effects can be seen. Based on research, it was found that there are long-term impacts on the landscape and environment but they are not so crucial. Water takes everything that comes its way, but the landscape itself can handle water very well. Drops of water soak into the ground or flow into the watercourse. The consequences of flooding depend on how much is the soil able to absorb water and how much time it would take. Unfortunately, this nature´s ability is distorted mostly by people and their actions. The water soil soaking is spoiled by buildings, badly tilled soil, inadequate food planting and destroyed hedgerows that serve as a hiding place for the animals. Maybe if the greatest importance was not emphasized on protecting people and their health, people would care more about the landscape and would be grateful for what nature offers and provides. The fundamentals of this work are solutions that would improve the environmental situation. The care should be taken not only to individual preventive measures, but to prevent floods and minimize their consequences. The starting point is to increase the retention, since the landscape has a short-term water retention problem.
