Landslide hazard analysis in national-scale for landslide risk assessment in Croatia

Abstract

Monitoring is important for assessing the stability of the ground and for confirming the validity of the design during the construction and operation of structures.The ideal monitoring system for projects in Rock and Geotechnical Engineering would be able to monitor the behavior of small to extensive areas continuously and automatically with high accuracy.In addition, the costs would be low and the system would be easy to handle.Satellite technology has the potential to realize the above monitoring system by combining it with conventional geotechnical instruments.In this paper, satellite technology for displacement monitoring, i.e., GPS and SAR, is firstly outlined and then the concept of spatiotemporal continuous displacement monitoring is introduced.The use of both satellite technology and geotechnical instruments is effective for geotechnical monitoring.Practical applications of GPS for landslide monitoring and collaborative researches using DInSAR with Balkan countries are described.
