STRESZCZENIE
Aim of the study:
To Genrate a landslide susceptibility map using Hybrid Approach of FR Model and Geospatial Technology for study 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 % is highly susceptible area, 26.2 % is moderately susceptible area and low susceptibility percentages are also found with a percent of 26.5 and a very low susceptibility was observed as 12.6 %. The susceptible classes of 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, with an AUC of 73.4 %. Therefore, it was shown by the assessment of the landslide susceptibility map that the approaches employed produced findings that were satisfactory.
