ABSTRACT: Throughout
the mountainous part of Pakistan, Murree is considered to host the worst slide
affected areas. Landslide risk assessment, mapping and analysis is a labour
intensive and time consuming work by using conventional field based methods. In
this study Geomatics techniques have been applied on digital data such as
satellite image and DEM, to investigate some possible causes of slope failure
in selected landslide risk zones. The Remote sensing technology and GIS
capabilities have been implemented using Landsat TM (30 m) multispectral data
and Aster DEM (30 m). Satellite image and digital elevation model have been
used to generate rock type map, aspect map, streams order map and slope map.
The possible factors of slope failure for different zones of land sliding have
been predicted by integrating information from all maps. It has been found that
major causes of slope failure have been addressed, also it has been noted that
water is the most dominant factor to cause land sliding in Murree area. Results
are available for supporting hazard studies, disaster management and future
development plans.
