Landslide Hazard Mapping of Bagh District in Azad Kashmir

Abstract

Landslide is a process which comprises creep movement, flow movement, rockfalls, snow avalanche and
soil flow on a slope. Human beings in hilly regions face catastrophe in the form of land sliding specifically during rain
time period. This paper will inspect the study of landslide hazard areas detection from NASA’s Shuttle Radar
Topography Mission (SRTM)’s Digital Elevation Model and moderate resolution Landsat-8 imagery over the district of
Bagh in Azad Kashmir by applying hazard evaluation technique of average weighted overlay method with 6 factors in
GIS environment. The outcome of this calculation is an area in the form of hazardous zones in eastern, north-eastern
and south eastern of Bagh district in AJK. Landsat-8 imagery is considered effective for observing topographies over a
large area while SRTM DEM (1arc second) with large global coverage provides elevation data with 30-meter
resolution. GIS technique like assigning weights (weighted overlay method) on different parameters of the landslide
can be helpful to policy makers and disaster management departments to overwhelm the serious situation during the
hazard.
