Clandestine flash flood in southern Moravia from 9 June 1970 (to commemorate the 40th anniversary of natural disaster which claimed 35 human lives). 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 basin of rivers Kyjovka and Trkmanka (left-bank tributaries of the Dyje/Thaya R.). The event was exceptional no only by the amount of fallen precipitation and by the discharge responses on the streams but also by the extent of domage 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. Moreover, this natural catastrophe happened in the period of culminating Communist "normalization", which mirrored in a considerable effort of government authorities to restrict the information about its disastrous impact.

Based on data from three group interviews conducted with groups of “workers” and “professionals”, this article focuses on ways that interviews participants choose in their attempts to cope with sociologists’ demands to describe social structure of the contemporary Czech society. The key category adopted from the interviewers’ questions around which the arguments of participants were centered is the category of “success“. The author analyses measures of success mentioned by participants, its presuppositions, who is regarded as successful by them and which criteria of success they adopt. Also analyzed is the self-positioning of the interview participants and the social group they identify with in the notions of social structure presented by them in the course of the interviews., Ivan Vodochodský., and Obsahuje seznam literatury
The aim of the study is to evaluate the circumstances revealed by the archaeological study of extinct medieval villages whose ground plans were staked out systematically, using some of the standard schemes of the times: that is, the possible direct proportion of the area, farmed by the individual homesteads, and the expanse of the plot of yards of these homesteads, or rather the width of the yards with respect to the village square. For the initial phase of the analysis were used the available early textual and cartographical sources from areas where such research was made possible by the earlier interconnecting of information about the history of settlement that allow for studying the older stages of social structure of the communities.
