Prototype of early warning system for areas at risk of landslides LandSMS – results of tests on the landslide in Klodne in flysch Carpathians.
A b s t r a c t. Mass movements are a major problem associated with the sustainable planning of space. They often cause permanent degradation of the areas of development or agricultural use. Exclusion of active landslides and periodically active landslides from development area is obvious. Restrictions on land use areas of active and inactive landslides and their buffer zones involve differences in opinions. A useful tool in the assessment of risk of landslide in such areas can be a low-cost system LandSMS (LandSlide Monitoring System). The prototype of the system consists of a sensing element (tie-rod), a monitoring station and a data server. Tie-rod is attached to the concrete slab, which is stabilized on the landslide area. Surface deformations resulting from movement of the landslide are controlled by two sensors – encoder and an ultrasonic sensor. The system operates continuously. In the case of an emergency situation system informs authorized persons about the incident. Efficiency and system functions are analyzed on a selected area of the landslide in Klodne (Little Poland, commune Limanowa). Preliminary results confirm the usefulness of the system. In the initial observation period (October–December 2016) displacement reached 8 mm. This is due to stabilization of the measuring point. Later, there was no displacement effected by mass movements reported.
