In the year 2007, enhanced rockfall activity was observed within the scarp of a 500 BP rockslide in the Reintal catchment (Northern Calcareous Alps, Germany). In this case study, the AA. focus on 3 aspects of rockfall research. First, they compile detailed geomorphological and geotechnical findings to explain the causes of the recent events. Second, they use digital elevation data from a pre-event airborne LiDAR survey (ALS) and post-event terrestrial laserscanning (TLS) to quantify landform changes and the mass balance of the rockfall event(s). Third, the event(s) is simulated using the results of the LiDAR surveys and a modified GIS-based rockfall model in order to test its capability of predicting the extent and the spatial distribution of deposition on the talus cone. Results show that the model generally reproduces the process domain and the spatial distribution of topographic changes but frequently under- and over-estimates deposition heights
