Combined risk of debris flow and slope mudslides

The data set presents the risk to the rail infrastructure from debris flows (mg) and slope murs (hm) in a spatially differentiated manner. This product of the debris flow and slope mud hazard is the result of the research project Analyses of fast water-bearing mass movements: Nationwide studies on the exposure of the German rail network and modelling of the spatial spread of the Federal Railway Office as part of the work of the BMDV expert network in the field of climate change impacts and adaptation (bmdv-expertennetzwerk.de). The factual information and hazard classes are provided exclusively for the rail infrastructure sector. The data basis for this is the data set geo-strecke (as of 10/2019), which is provided by Deutsche Bahn (DB) under the license Creative Commons Attribution 4.0 International (CC BY 4.0) (http://data.deutschebahn.com/dataset/geo-strecke). The potential risk areas of the rail infrastructure of small, medium and large potential simulated events are presented (see the final report of the project on the dzsf website (www.dzsf.bund.de)). The hazard attribute distinguishes these three hazard classes (1 = small event, 2 = medium event, 3 = large event) as well as 0 = no hazard and 99 = tunnel. In this data set, the potential simulated events of the debris flows and slope murs are combined. A process differentiation is possible via the view of the data sets debris flow hazard and slope mud hazard. The following applies to the size of the simulated cubatures: <100 m3: small event 100-1000 m3: mean event ≥ 1000 m3: large event The record does not represent the probability of occurrence of the events. Existing protective measures and thus secured areas were not taken into account in the modelling.
