Abstract

Mass displacement of materials such as land slid is one of the problematic skirt processes in JAVANROOD CATCHMENT AREA located at the north west of folded Zagros, because this phenomenon makes the degradation of forest lands, agriculture lands and pastures of this region, and deemed to be a threat for road traffic. Therefore, identification of the zones sensitive to land slide has a great importance for the habitants of the area. The present study has been performed in this regard and for this Purpose, the two variables statistical method of the surface compaction has been used.To this end. firstly, transmittal layer of the happened 31 sliding points at the catchment area were prepared as dependent variable and 8 layers influencing on the sliding occurrence like litho logy, slope, distance from road, distance from drainage, distance from habitats, skirt direction, skirt’s morphology and land uses were prepared as independent variables. After wards, through over lapping and one by one cutting of agent maps with land slide distribution map dependently and separately, the land slide surface density at each class or category of the above factors were calculated. Then by combining and integrating the weight values of all layers with the assumption of the existence of a minimum correlation between each variable with the other, ZONING map of land slide potential at 4 levels, zone with very high risk, zone with high risk, zone with medium risk and the zone with low risk were obtained. The results has shown that from the view point of lithology, the highest occurance of land slide have been on Goorpei and Radiolarit. In terms of slope, the slope level of %6- %18, from the view point of the skirts orientation, the skirts towards north east and from the view point of the skirt’s form and land use, hill dale lands with convex, regular skirts covered by destructed chestnut forest, have allocated the greatest amount of land slide to themselves. But the most important result has been the following of the most density of sliding points up to radios 200m far from the road and drainage bed. Based on these results, about %65 of the lands of JAVANROOD CATCHMENT AREA has the potential of sliding with high and very high risk.
