Murgangsgeehrdung (debris evacuation)

The data set presents the risk to the rail infrastructure caused by debris flows in a spatially differentiated manner. This product of the debris flow hazard is the result of the research project "Analysis of fast water-containing mass movements: Nationwide investigations on the exposure of the German rail network and modelling the spatial spread" of the Federal Railway Office in the context of the work of the BMDV expert network in the field of climate change effects and adaptation (bmdv-expert network.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 Creative Commons Attribution 4.0 International (CC BY 4.0) license (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) and 0 = no hazard and 99 = tunnel. 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.本数据集以空间差异化的方式呈现了泥石流对铁路基础设施造成的风险。该泥石流灾害风险产品源自德国联邦铁路办公室（Federal Railway Office）在BMDV气候变化影响与适应领域专家网络（bmdv-expert network.de）框架下开展的研究项目——“含快速水体块体运动分析：德国铁路网暴露范围的全国性调查与空间扩散建模”。 本数据集仅面向铁路基础设施领域提供事实信息与灾害等级划分。其数据基础为德国铁路（Deutsche Bahn，DB）于2019年10月发布的“geo-strecke”数据集，该数据集采用知识共享署名4.0国际许可协议（Creative Commons Attribution 4.0 International，CC BY 4.0）进行授权，相关数据可通过http://data.deutschebahn.com/dataset/geo-strecke 获取。 本数据集展示了小规模、中等规模及大规模模拟泥石流事件下铁路基础设施的潜在风险区域，相关细节可参见德国岩土工程与灾害研究中心官网（www.dzsf.bund.de）发布的项目最终报告。灾害属性字段区分了四类标识：1代表小规模事件、2代表中等规模事件、3代表大规模事件，0代表无灾害，99代表隧道。模拟泥石流体量的判定标准如下：体量小于100 m³为小规模事件，100~1000 m³为中等规模事件，不小于1000 m³为大规模事件。 本记录不代表事件发生概率，建模过程未考虑现有防护措施及受其保护的区域。
