A national assessment of landslide hazard from Outside Party Slopes to the rail network of Great Britain

Abstract

In recent years, a number of high profile landslide events have caused disruption, derailments or damage to railway infrastructure in Great Britain. A landslide susceptibility model of the entire railway network was created, designed to give a national overview of potential landslide hazard originating from Outside Party Slopes. The current assessment was compiled using Geographic Information System (GIS) techniques and desktop modelling to apply a structured analysis of each buffered Earthwork Inspection 5 Chain (c 100 m). Data analysed along the network included the BGS GeoSure instability model 19 and newly updated national models for debris flow, earth flow and rock fall, supported by 20 historic landslide data. In order to further focus the Outside Party Slope zone, a buffer of 21 External Natural Geological Influence (BENGI) was created using 5 m Digital Terrain Model. 22 Landslide susceptibility for each Earthwork inspection 5 Chain was categorised using a 23 'Classification of Hazards on Outside Party Slopes' (CHOPS) score; representing the modelled 24 potential for landslide hazard. 25 The outputs were combined as a series of matrices to present the CHOPS and Network Rail 26 Derailment Criticality Band interactions. This research will allow further focused analysis of 27 the network, in order to prioritise and direct future investigation and policy decisions. 28

Big Data for Natural Disasters in an Urban Railroad Neighborhood: A Systematic Review

“…Landslides have the potential of affecting the railroad network, so it is necessary to prevent these risks. Several authors propose strategies, including identification of scars from landslides through photo interpretation; risk maps generated by algebra from thematic maps such as pedological, geomorphological, land use and cover, lithologic and hypsometric [23]; the creation of a model of susceptibility to landslides with support from instability and updated models for flow of debris, land, and rock falls [24]; application of databases to analyze the susceptibility to landslides [23]; among other methods. Entry parameters to evaluate the susceptibility to landslides between Kral'ovany and Liptovský railroad sections in Mikuláš, Slovakia were used by [22].…”

Interpolation of Single Beam Echo Sounder Data for 3D Bathymetric Model

“…They are fundamental for many applications, i.e. 3D thematic model construction [12], assessment of potential groundwater vulnerability to pollution [13], assessment of potential dam sites [14], landslide hazard [15,16], satellite images orthorectification for useful applications in coastal area studies [17], etc.…”
