Mass movement susceptibility maps offer a quick and effective way to determine areas that people should not exploit or where it is known that any development would require special construction and other measures. In recent years, such maps have been made for landslides, rockfalls, and debris flows at the national scale for Slovenia, and the first maps for municipalities have also been created. This article presents the current state of production of such maps in Slovenia.

The article presents the acquisition of data from non-metric images with the help of photogrammetric DTM and LIDAR for the floods on Ljubljana moor (Ljubljansko barje) in September 2010. Images made with non-metrical camera Cannon PowerShot SX10 IS were used. Terrestrial oblique imaging was made in the time of the highest waters and the imaging from helicopter in a time when floods were already retreating. The flooding boundary was measured from the non-metric images with the interactive orientation of image on the DEM. This is a monoplotting method, which enables 3D data acquisition from only one image. The method is based on the manual interactive search for the best fit of the superimposed 3D points of DEM onto the details seen on the image. When image is oriented correctly the superimposed DEM points fit to the image very well.

This study identifies factors that affect the speed of rockwall retreat of flysch cliffs between Kane Point and Strunjan on the Slovenian coast. Individual factors were combined in a geographical information system with mapped recent erosion features. The results indicate the influence of individual factors on the formation of erosion rills, gullies, surfwave breaks, slumps, and rockfalls; that is, flysch coast retreat processes. Special attention is dedicated to the occurrence of major slope processes, specifically slumps and rockfalls, which are an important contributing factor in cliff retreat. The article also presents the threat to individual sections of the coast due to rockfalls and slumps.
