INTEGRATION OF THE MEASUREMENT TECHNIQUES USED FOR MONITORING THE LAZE LANDSLIDE IN SLOVENIA

The slow movement of the terrain in the area of the village Laze in the municipality Gorenja vas-Poljane accelerated significantly after heavy rainfall in early 2014. Research was conducted to determine the volume of the landslide, the depth of the sliding plane and the displacement dynamics. During a study of the creep sliding dynamics we found the old orthophoto plans and a comparison of the cyclic aerial imagery very useful. The article describes the monitoring system that has been established and describes innovative procedures for using existing spatial data for a better interpretation of the movement dynamics. These comparative analyses of the absolute or relative shifts are useful for land-use planners and for risk analysis as a part of an environmental policy.
