The purpose of this study was to assess WINF and BLR methods application for mapping of landslide zonation in Pahne-kola sub-watershed located in the south of Sari, Iran. For this purpose, after field investigation and review of similar studies, 8 factors, including hypsometry, precipitation, slope, aspect, land use, distance from roads, soil and lithology, were identified as the effective factors of land slide. Later, the information layers of these factors and information layers of landslides of this region were prepared in GIS. These information layers were adapted with land slide distribution layer and the landslide information layer was obtained as a quantitative information layer. Afterwards, by using WINF and BLR methods, the landslide zonation map was created in GIS. Finally, application of the two methods was assessed by comparison with the frequency of landslide percent on high hazard classes (high and very high hazard). The results showed that for WINF and BLR methods, respectively, 72.2% and 65.56% of the landslides were in the high and very high classes. Therefore, the WINF method is better than the BLR method.
