Recent (1997) extreme precipitation led to extensive floods in the northern Moravia and also triggered landslides in the Czech Republic in general. Enormous saturation of rocks by atmospheric water caused disturbance of slope stability in the Carphatian flysch formation, which led to a vast damage on buildings, highways, railroads and infrastructure in general. The objective of the project is to define and elucidate on the pole of atmospheric water and groundwater. Detailed studies of rock deformation will result in quantification of risks, which may arise in flysch sediments of the model area of the Vsetínská Bečva river basin in future. The obtained data will by also used for categorization and classification of slope deformations and construction of assessment maps of model area. These data will complete and define more precisely the existing methods of assessment of environmental risks of landslides in the Czech Republic and to classify single localities according to the degree of exposure of the population, buildings and infrastructure to the danger of landslides. The assessment maps of the mostly endangered regions in the Czech Republic will represent the final output of the project. The maps of risks will serve for decision-making in terms of urgency and/or pertinent maintenance of slope deformations in the model area and for town planning in individual regions of the Czech Republic.
