Integration of geographic information system-based method in weight assignment and parameter justification for rockfall hazard rating system

The purpose of this study is to do a comparison study of integration of heuristic AHP and GWR methods in predicting rockfall hazard. Rockfall Hazard rating System (RHRS) has been an established method to monitor the rockfall hazard leading to development of other system to study rockfall across diff...
