The Ligvan-chai basin is located on the north slope of Sahand mountain.The evolution of this basin is inseparable from the Sahand mountain transformation. Due to dominant of the perglacier and fluvial erosion systems, on the north slope of Sahand mountain, Mass movements, fluvial flows and flood are the morphogenic phenomena and the geomorphological hazards in the Ligvan-chai basin. These events threated the cities and rural settlements. They prevente to progress development programes. This study present the zonning of mass movements hazard on the Ligvan-chai .It try to mapping of the mass movemnts hazards and recognition of high hazard – low hazard regions, so that planners and managers lead to planning and accurate management of landuse.Therfore,it is possible the development of agricultural, settlements and industrial sections, in the area of faraway the geomorphological hazards. The zonning of mass movemnts hazard’s map draw by the digitaly topography maps (1: 250000 and 1:50000), geology and geomorphology maps,Remote sensing data,GIS(Arc/Inf and Arc/View). The variaibles are slope, distance of fault, distance of stream, distance of rurale, distance of route, precipitation, litology and landuse.Results indicated that , 36.11% of the study region is located on the medium zone–very high hazard,the point view of mass movements hazard.

Keywords: GIS, Zonation, Geomorphologic hazards, Mass movements hazard, Sahand mountain, Ligvan-chai
