abstract="his study aimed to determinationof the topographical effects of slope, aspect and geological factors (type offormation) on the landslides occurrence in the Ardal, Bazaft and Koohrangbasins located in Chahar Mahal and Bakhtiari province using statistical method wasperformed, therefore using available data in the Arc Gis software the slopemaps in three classes and the aspect maps in four classes were provided, from thegeological formations in each basin two formations with the most landslidenumber were elected as well, and with overlapping maps homogenous regions were obtained,to be possible using factorial experiments and randomized complete block, threereplications from each homogeneous were measured, Thus 72 sliding surfaces wereinvestigated in total and determined their occurring landslides number whichthey were used in the statistical analysis using analysis of variance and meancomparison using Duncan's multiple range tests, Basedon the obtained results the role of slope and aspect in the landslidesoccurrence were significant at the level 0.01,Also over mean comparison forthese factors, the south aspect and low slope (0 to 10%) has highest mean(8.333 and 10.292 landslide, respectively) and consequently they had the mostrole in landslide occurrence. <br><br>KEYWORDS: Factorial experiments,Duncan's multiple range tests, analysis of variance, SAS, GIS<p /> <p>Language: en</p>",
