Risk Mapping Analysis With Geographic Information Systems for Landslides Using Supply Chain

Among the various natural disasters, landslides are considered to be one of the serious geological hazards that are triggered due to intensive rainfall, earthquakes, deforestation, mining, floods, etc. Landslides result in devastating impacts causes thousands of deaths and injuries, damage to properties. The changing pattern of landslide hazard zones every year forces the need to safeguard people and properties in the respective areas. Weighted linear combination (WLC) is used to prepare the landslide hazard zonation map in the Nilgiris district of Tamil Nadu, India. Nine layers, namely slope, aspect, lineament density, rainfall, distance of roads, elevation, distance from rivers, landuse/landcover, geology, are used in overlay analysis. Supply chain facilities are widely used in the field of transportation of goods to the consumers with the reduction of transportation costs. The implementation of supply chain mechanism along with GIS in disaster management could help to save numerous lives during disaster events.
