摘要:The dynamics of the cultural landscape is associated with the penetration of people into the natural landscape, the settling and adaptation to the needs of the society and its development.Climate creates the decisive influence, specifically the form of extreme high rainfall causing flooding.Adverse impact on the cultural agricultural landscape is mainly the submersion time.This time depends on the configuration of the terrain, its disposition and the existing drainage ditches in the area ensuring the drainage of the flood to the recipients.Long-lasting floods have stipulated taking measures both for the protection of the area from flooding by building dikes and drainage of the flood from the area.Identifying the extent of extreme floods and zones of permanent waterlogging is currently provided by modern technology which allows recording of satellite images in different spectral bands.Within the basic distinguishing signs mainly accruing is used and it is possible to track changes of the extent of flooded areas and thus identify problem areas insufficiently protected against long-term flooding.Consequently, it is possible to solve the concept of exploiting such areas to keep them in the structure of PPF or their reclassification in wetland systems with the necessary legislative security.The aim of this paper is to show the possibility of using satellite images in identifying the extent of flooding in flood.
