Extreme hydrological events in the context of urban planning
Klimeš, Zdeněk ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The purpose of the bachelor thesis was to describe known extreme hydrological events and potential attitudes to minimalize their negative impacts. The thesis was written as literature recherche from different points of view, not only from a one-sided technical or ecological point. It proceeds systematically from describing the historical evolution of the subject matter through the presentation of global ecological problems, outlining the legislative background and the findings from specialised literature, to the examples of current trends. In view of the fact that the issue is so broad, the thesis treats only certain parts in detail. The subject of interest is the demonstration of separate measures against floods and droughts and the effects of their synergy concerning the minimalization of the repercussions of extreme hydrological events.

The influence of extreme precipitation on washout of potassium and sodium ions from the Liz basin in the period of 2002-2009
Vondrka, A. ; Tesař, Miroslav ; Šír, M.
Extreme rains strongly influence the intensity of leaching of sodium and potassium from the soil cover. The question therefore arises whether it is possible to find some connection between extreme rains and sodium and potassium leaching. During the period of 2002-2009, measurement of rainfall, runoff, and chemical data on catchment Liz (Czech Republic, Bohemian Forest, 828–1074 m a. s. l., mature spruce forest, Podzolic Eutric Cambisol) gave the following conclusions about the washout of potassium and sodium ion from the basin: (1) In monthly periods, extreme loss of both potassium and sodium ions correlated with high precipitation amounts. (2) In annual periods, only extreme loss of sodium ions correlated with high precipitation amounts.
