Abstract :

Slope discontinuity is one of the main factors of the change of geometrical form ofthe regional reliefes. Product transportation of denudation is from the highest landsand mountains to valleys and then toward the sedimental basins.The mass movementsof the slope materials like slip and slope discontinuity cause this and of course is thereason of the movement of large amount of slope material toward the valleys. Now theroad between Ardebil-Astara is changing because of the processes of slip and slopediscontinuty.In fact the existence of the factor like Lithology, the distance from the fault,vegetation, gravity force and change in the degree of slope, loading and the totalweight of the slope material, kind, classification and thickness of the material,rainwater, melting snow and ice, watering, topography situation and directioning of theslopes,land using and human factors cause the instability and discontinuty of theslopes throught the referred aea. So the map of the classifying the area with thepotential of landslide in this region is provided by the Arcview GIS software.
