Sažetak
The Kostanjek landslide is the largest landslide in the Republic of Croatia, located in the western residential area of the City of Zagreb. The landslide was activated in 1963 and the main cause of sliding was excavation of the marl at the foot of slope. Investigation of Kostanjek landslide is one of the objectives of the Japanese-Croatian five-year (2009-2014) scientific joint-research project “Risk Identification and Land-Use Planning for Disaster Mitigation of Landslides and Floods in Croatia”. As a part of scientific project, a real-time monitoring system was designed during the period from 2010 to 2011 and established in the period from 2011 to 2013. The monitoring system consists of multiple sensor networks including 15 GNSS sensors for displacements monitoring. By GNSS sensors displacements of only 15 points can be monitored. From UAV surveys, movements of the landslide as well as changes in the surface topography can be detected, which enables us to obtain more detailed information on landslide dynamics, necessary for studying landslide activity. In this paper, results of three periodic UAV surveys of landslide performed within a period of two months are shown. Since within this period, no significant displacements on landslide had occurred, we examined the achieved accuracy of UAV surveys. Survey was done using senseFly eBee RTK with integrated GNSS RTK receiver. Since, in many cases there are sites where ground control points (GCP) cannot be placed and measured easily or safely, in this paper we analyzed the achieved accuracy of survey with and without the use of GCPs.
