“…These factors make it difficult to assess if specific floods will develop near-bank shear stresses capable of causing localised or mass slope failures. However, flooding scour of slopes is important to consider due to toe scour and undercutting as potential causes of landslides (Freeborough et al, 2016, Perry, 1989. Parallel flow is more likely to cause scour and failure of slopes with granular faces, due to reduced erodibility of cohesive materials (Julian and Torres, 2006, Thorne, 1982, Hooke, 1980.…”

“…As described in Freeborough et al (2016), a scientifically based 1:50 000 scale assessment of 103 the potential susceptibility to natural slope failure at a location is provided by the national 104 GeoSure: slope instability (Landslides). Data on slope angle, material strength and the known 105 susceptibility to instability of different lithologies, are combined using a multi-criteria and 106 heuristic approach; applying a series of rules against the available data to provide a hazard 'score' at each location (Lee & Diaz Doce 2014).…”

“…Previous research has included a detailed regional study of a particular route, detailed Digital Terrain Models and field verification and assessment. This was followed by a feasibility overview of the application of a single landslide susceptibility model derived through a similar methodology in relation to the full network (Freeborough et al 2016). Both projects proved successful on a local and national level, however identified a limitation on data and terrain model scales applied to the national level (Freeborough et al 2016).…”

“…This was followed by a feasibility overview of the application of a single landslide susceptibility model derived through a similar methodology in relation to the full network (Freeborough et al 2016). Both projects proved successful on a local and national level, however identified a limitation on data and terrain model scales applied to the national level (Freeborough et al 2016). The current successful methodology builds and evolves on both approaches, employing new and improved spatial modelling for differing landslide types and applying these to the full network at a suitable scale.…”

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

“…The landslide hazard has been a topic for many research studies like Carrara et al (1995), Klimeš (2007), Havlín et al (2011), Bibi et al (2016), Razak and Mohamad (2015), Freeborough et al (2016) etc. It is a form of mass movement in which the rock, debris, or earth moves down along slope, under the influence of gravity (Cruden and Varnes, 1996).…”

ABSTRACT:Landslides are an inescapable natural disaster, resulting in massive social, environmental and economic impacts all over the world. The tropical, mountainous landscape in generally all over Malaysia especially in eastern peninsula (Borneo) is highly susceptible to landslides because of heavy rainfall and tectonic disturbances. The purpose of the Landslide hazard mapping is to identify the hazardous regions for the execution of mitigation plans which can reduce the loss of life and property from future landslide incidences. Currently, the Malaysian research bodies e.g. academic institutions and government agencies are trying to develop a landslide hazard and risk database for susceptible areas to backing the prevention, mitigation, and evacuation plan. However, there is a lack of devotion towards landslide inventory mapping as an elementary input of landslide susceptibility, hazard and risk mapping. The developing techniques based on remote sensing technologies (satellite, terrestrial and airborne) are promising techniques to accelerate the production of landslide maps, shrinking the time and resources essential for their compilation and orderly updates. The aim of the study is to provide a better perception regarding the use of virtual mapping of landslides with the help of LiDAR technology. The focus of the study is spatio temporal detection and virtual mapping of landslide inventory via visualization and interpretation of very high-resolution data (VHR) in forested terrain of Mesilau river, Kundasang. However, to cope with the challenges of virtual inventory mapping on in forested terrain high resolution LiDAR derivatives are used. This study specifies that the airborne LiDAR technology can be an effective tool for mapping landslide inventories in a complex climatic and geological conditions, and a quick way of mapping regional hazards in the tropics.
