Roadside slope failure is a common problem in the Himalayan region  as road  construction  activities  disturb natural slopes. Therefore, landslide susceptibility zonation is necessary for roadside slope disaster management  and  planning  development  activities.  In  this study, we consider a 53-km section of a major highway in Nepal where road services are suspended for several days  in  the  monsoon season  every  year. A  number of methods  have  been  used  for  landslide  susceptibility zonation.
