Based on landslide database a Landslide susceptibility map of Slovenia at scale 1 : 250,000 was completed. More than 3,200 landslides were used for analyises. Random but representative 65 % landslides were used for the univariate statistical analyses (?2) to analyse their occurrence in relation to the spatio-temporal factors; lithology, slope inclination, slope curvature, slope aspect, distance to geological boundaries, distance to structural elements, distance to surface waters, flowlength, and landcover type. The analyses were conducted using GIS in raster format with the 25×25 m pixel size.
The basis for developing climate change scenarios are simulations of GCM (global climate models). The horizontal resolution of these models is too coarse to be directly applicable to the local level. This gap was overcome using the dynamic-statistical approach to reducing the scale. With a calibrated method to adapt the distribution of the meteorological variables, projections of results of RCM (regional climate models) simulations were made.
On a small area an analysis of usefulness of permanent scatterer technique (PSInSAR) for landslide monitoring was performed. Based on the terrain properties, displacement vectors of permanent scatterers and anticipated movement directions of sliding masses actual displacements as a consequence of these slope mass movements were quantified and compared. We compared the correlations of temporal displacement series of permanent scatterers and concluded that they could be spatially related.
For the period from 1996-2006 data on precipitation at different temporal intervals (30 min, 1 h, 2 h, 3 h, 6 h, 12 h, 24 h) for the weather station Rateče were analysed and a) rainfall intensity index, b) number of rainy days, and c) monthly rainfall erosion index were calculated. Daily rainfall above 40mm is most frequent in the fall and there's more than 10 such days annually. Monthly rainfall erosion index is the highest in August, while it is relatively low for winter and spring period.
Differential interferometry (DInSAR) and permanent scatterers interferometry (PSInSAR) were used to observe co-seismic temporal surface deformation related to Posočje earthquake (April 12, 1998). A comparison of both methods was performed. DInSAR enables surface observation and PSInSAR enables temporal point observation. Limitations of PSInSAR are complex interpretation, inability to observe vegetated areas and quick deformation observation.
