Temperature oscillations: An example from pravcicka brana rock arch (Czech Republic)

Abstract

The paper discusses the results of the research devoted to the preservation of natural heritage site carried out at Pravcicka Brana Rock Arch located in Bohemian Switzerland National Park, Czech Republic., the largest natural sandstone bridge in Europe. The aim of the study was laid on the relationship between spatial temperature distribution and rate of displacement, as the response to temperature oscillations and to find out kinematic behaviour (deformations dynamics) of the rock arch using computer modeling to simulate if there exists any potential hazard to sandstone body rock arch to collapse.
