A Mesoscale scale landslide susceptibility methodology has been derived with an aim to produce a susceptibility map
that can define the susceptibility of a slope to a specific process of landsliding so that it can be used by stakeholders
for detailed planning in landslide management and infrastructure developement. The methodology is based on
intensive field and laboratory input. The mapping in such a large (1:10.000 or larger) scale helped in defining the
domains based on slope material and processes. Domain specific geo factors were derived using the knowledge of
landslides in the terrain. To define the actual slope mass character, geotechnical map was prepared using RMRbasic and slope for rocky areas; C and Φ values as well as the slope, in debris and soil covered areas. The modelling was
carried out in ArcGIS 10.3. Various geo-factors for landslidi.. View More»
