Saturation of the Czech territory by precipitation before extreme precipitation totals
Laco, Martin ; Müller, Miloslav (advisor) ; Ledvinka, Ondřej (referee)
The saturation of the river basin is one of the important factors that contribute to the occurrence of significant floods. Examples of floods where significant previous saturation played a significant role are, for example, the floods of 1997, 2002 and 2013. A more detailed description of saturation before heavy rainfall in the Czech Republic was missing. The main goal of the work was therefore to describe the distribution of saturation using a suitable index of saturation before cases of heavy precipitation in the Czech Republic, and also to try to describe the degree of risk associated with high saturation in combination with heavy precipitation, using the proposed indicator of the importance of relative saturation. Based on the results of the work, we can say that, in general, the saturation before heavy precipitation totals can be diverse (mainly for the shortest analyzed time intervals), but on average it is rather normal. It is slightly increased in the mountain area, especially in the east of the country and for strong precipitation totals of the longest analyzed time intervals. However, when taking into account the extremity of heavy precipitation totals, it turns out that the saturation tends to be significantly increased mainly for the heaviest precipitation of longer time intervals in...
