Flash flood in southern Moravia from 9 June 1970 – natural disaster which claimed 35 human lives
 Munzar, Jan ; Ondráček, Stanislav
The article is devoted to a today already forgotten flash flood, which was considered extreme from multiple viewpoints. It happened 40 years ago, on 9 June 1970, in the Kyjov region in southern Moravia on several small watercourses in the basins of Kyjovka R. and Trkmanka R. (left-bank tributaries of the Dyje/Thaya R.). The event was exceptional not only by the amount of fallen precipitation and by the discharge response on the streams but also by the extent of damage caused by storm waters. Nevertheless, the flood had more attributes, which point out its extreme character. By the number of 35 victims it ranks among the most tragic (not only local) floods that occurred in the territory of the Czech Republic in the 20th century.

Design of early warning system against lightning floods in mountain conditions
 Tesař, Miroslav ; Šír, Miloslav ; Polívka, Jiří
The sophisticated local warning system against flash floods in mountain conditions is described. It is designed using the latest knowledge on the hydrodynamic mechanisms of storm runoff. It was found that extreme discharges are caused by these factors and their combinations: (1) saturation of soil cover with water, (2) soil surface hydrophobia, (3) gravity destabilized flow of water in the soil, (4) extreme rainfall, usually after prolonged dry period. Typical combinations causing extreme runoff, are (1) and (3) - the water saturation of soil cover can cause gravity destabilized flow induced by a small rain, (2) and (4) - long-term drought may cause the hydrophobic surface of the soil and simultaneously trigger extreme rain.
