Conference paper


Since 2011 the scientists have been working on the establishment of the Kostanjek landslide monitoring system in Zagreb (Croatia) in the frame of the Croatian-Japanese SATREPS FY2008 Project. The system consists of sensors for measuring displacement, hydrological properties and external triggers. The total rain quantity of 455.2 mm, which fell in the winter period of 2012/2013, caused a reactivation of the landslide. Displacements in the range of 9–20 cm have been recorded by GNSS sensors and extensometers in various parts of the landslide surface (an area of 1 km2). This paper briefly presents measured displacements which pointed out the necessity to establish an early warning system (EWS). Monitored data will be used for the prediction of landslide failure and for the establishment of the threshold values for an early warning system. The final user of the early warning system will be the City’s administration for civil protection.
