PSInSAR displacements related to soil creep and rainfall intensities in the Alpine foreland of western Slovenia

摘要: Abstract An assessment of the relationship between displacement rates objects located in areas active soil creep and rainfall intensities was performed using a permanent-scatterer technique synthetic aperture radar interferometry. The study focussed on two central Slovenia during period April 1992 December 2000. Based field assessments, six permanent scatterers for one area 11 other were selected analysis from > 4300 available scatterers. Displacement related to creeping processes compared with different durations rain order assess threshold values that initiate process speed movement precipitation events. Although scatterer data contain much noise, our results indicate is induced by 20 mm 1 day or 50 mm 3 days, causing an average elevation decrease 0.5 1 mm, respectively. decreases due observed as instantaneous events, since no increased correlations when time lag taken into account. Models developed this research indicated very similar tectonic uplift event rain, these found be faster than regional uplift. This suggests high may related.
