Abstract
New early-warning landslide monitoring system is presented in the paper. It was installed in Beskid Niski Mountains in Małopolska Province. The system is the first of this type in Poland and it was constructed within the EU Project “Innowacyjna Gospodarka”. Four field monitoring stations were located over Szymbark–Bystra public road. Six active landslides have been detected in this region. They have depth of 7–20 m and are founded in soft clayey soils interbeded by the sandstones. The system consists of different kinds of ground movements measuring devices including modern 3D inclinometers. It includes two continuous inclinometer systems down to the depths of 12 and 16 m. It also includes standard in-place inclinometer installed in a borehole. The influence of a groundwater conditions on mass movements activation is being investigated by the three fully automatic pore pressure and groundwater depth transducers. The weather conditions are being analyzed by automatic meteorological station which measures precipitation, air humidity, temperature and pressure values. The system was installed in May–June 2010. The field data are collected at each 1-hour interval and transferred by GSM network to the Internet. Three year period of monitoring has been planned and it includes early warning of potential threats for the public road as well as for the newbridge over Bystrzanka river.
