SLOPENET – a network for monitoring of the development of various types of slope movements. Measurements take place continuously in Czechia, Slovakia, Bulgaria and the Canary Islands. SLOPENET plays a crucial role in the protection of the population and property. Current state-of-the-art monitoring methods include real-time data analysis using a variety of methods and sensors. These include surface, subsurface and distance methods. Surface methods include various methods of monitoring surface deformations and movements (e.g. crack meters, extensometers, or geodetic methods). Subsurface methods include, in particular, monitoring of the groundwater level, inclinometric measurements or monitoring changes in rock environment parameters (e.g. water saturation) by measuring changes in pore pressures or geophysical methods. Distance methods then involve the use of data obtained from aerial or satellite measurements. Despite the indisputable advantage provided by distance data (coverage of a large area), their use in Central Europe is very limited, especially due to vegetation, which prevents detailed monitoring. The most accurate results are still achieved by subsurface methods, despite the disadvantage of only local information. Only subsurface methods make it possible to characterize local conditions and their changes over time in sufficient detail and thus take into account local specifics in the development and dynamics of deep-seated slope movements.
