STRESZCZENIE
Aim of the study:
To generate a landslide susceptibility map using Hybrid Approach of FR Model and Geospatial Technology for the studied area.
Material and methods:
Application of FR Model and GIS
Results and conclusions:
According to the FR method, 11.5% areas are very highly susceptible to landslides, 23.2% represents highly susceptible area, and 26.2% represents moderately susceptible areas. Low susceptibility areas constitute 26.5%, and very low susceptibility areas, 12.6%. Susceptibility classes in the final map were derived from FR method, grouped into five risk levels and examined with the value of area under curve (AUC). When it came to zoning the study regions in relation to past landslides, the FR model produced an AUC of 73.4%. Therefore, using the assessment of the landslide susceptibility map, it has been demonstrated that the approaches employed produced findings that were satisfactory in their reliability.
