potential debris flows Hangmuren

The dataset shows the potential flow paths and ranges of simulated debris flows (mg) and slope murs (hm) along the German rail network. This product of the potential debris flows and sloping murs is the result of the research project "Analysis of rapid waterborne mass movements: nationwide studies on the exposure of the German rail network and modelling of 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 adjacent area of the rail infrastructure. The potential simulated debris flows and hangmurs are shown in gradation of size according to small, medium and large events (see final report of the project on the website of the dzsf (www.dzsf.bund.de)). Value 1 = small event, 2 = medium event, 3 = large event. 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 100–1'000 m3: mean event ≥ 1'000 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.本数据集呈现了德国铁路沿线模拟泥石流（debris flows，代号mg）与边坡泥流（slope murs，代号hm）的潜在流动路径及波及范围。该潜在泥石流与边坡泥流数据集成果，源自德国联邦铁路管理局依托德国联邦数字与交通部（BMDV）气候变化影响与适应领域专家工作组（bmdv-expert network.de）开展的研究项目——"快速水携块体运动分析：德国铁路网暴露度全国研究与空间扩散建模"。本数据集仅针对铁路基础设施毗邻区域提供实况信息与危险等级划分结果。潜在模拟泥石流与悬移泥流（hangmurs）的规模按小型、中型、大型事件分级展示，分级标准详见dzsf官网（www.dzsf.bund.de）发布的项目最终报告。其中等级1对应小型事件，等级2对应中型事件，等级3对应大型事件。本数据集整合了潜在模拟泥石流与边坡泥流事件，用户可通过泥石流危险性数据集与边坡泥流危险性数据集实现过程类型的区分。模拟体积的规模判定标准如下：小于100立方米为小型事件，100~1000立方米为中型事件，大于等于1000立方米为大型事件。本数据集不代表各类事件的发生概率，建模过程未考虑现有防护措施及由此划定的安全区域。
