The flash flood driven land use changes: Case studies from the Czech Republic

Original language description

The economic and construction development of an area takes place on the basis of the participation of many factors, based mainly on the natural and social spheres. These &quot;localisation&quot; or &quot;development&quot; factors are often a crucial backbone in explaining past events and in planning and decision making of public administrations or private entities about upcoming changes also in land use. Dominant orientation on traditionally time-varying socio-economic indicators, however, sometimes neglects the second essential component in the development of the territory - namely, dynamic natural factors, physical-geographic, and in particular dynamic factors and phenomena. They are perceived as incidental, except for those associated with the phases of the annual cycle, as they correspond to the seasons. The natural components of the landscape (geological environment, terrain parameters, water and climatic conditions, soils and biota) represent significant localizing factors of human activities and factors limiting the choice of appropriate activities for a particular area. Some of their short-term manifestations, especially atmospheric and/or hydrological phenomena, can cause a number of severe limitations for the socio-economic sphere. At present, we can encounter a number of extreme natural phenomena, the incidence of which has increased so much that it represents a serious threat to the continued development of many small localities but also larger territorial units. On a global scale, the impacts of climate change on a regional or local scale are manifested, amongst others, by the occurrence of frequent floods, periods of extreme drought or tornados. Particularly the last two decades are characterized with the increased occurrence of extreme atmospheric and hydrological phenomena with adverse effects on human society. Floods, among other things, are well known to the public and the experts due to the wide publicity in the media, but also a great attention is paid to basic and applied research of such phenomenon. The main focus of the research is especially oriented to the prediction of regional floods, affecting catchment area in the order of tens of km2 and more. It is mainly about the inventory and the analysis of conditions and causes of such floods, the modelling of their course and their extent, and the acquired knowledge should serve both the prevention and especially the early warning. A less noticeable attention is given to flash floods as they are considered as of &quot;incidental&quot; occurrence, with a rapid course limiting predictive and warning capabilities. However, the massive damages, and especially the lost of the victim lives, are not so big as in the regional floods. The reaction of human society to flash floods aims to reduce damages to human constructions and to develop ways to mitigate or to prevent their adverse impacts in the future. However, the statistical data (from Hungary) do not yet show a high probability of the flash flood repeating at the same site and legitimacy of taken measures. In any case, the reaction of the affected localities seems to be somewhat logical, e. g. in the development of land use, as it is demonstrated below by examples from the territory of the Czech Republic. The relationship between flood and land use is predominantly studied as the impact of land use changes on the nature of the flood. Typical are studies of the Impact of Land Use Changes on the Inundation Size in a Historical Context. The opposite effect, i.e. a land use change as a result of the flood, is studied much less and concerns measures to capture the large water in reservoirs, forest stands, or to facilitate safe outflow through hydrotechnical structures. The impacts of flash floods on land use have so far not been studied.
