Abstract: 

The mass movement is one of the natural hazards which with regard to frequency and its strength has two consequences direct consequences (blocking the rods and the direction of waterways, burring the residential areas and service installations) and indirect consequences (environmental unpleasant effects, becoming the soil useless, increasing the sediments and dregs and decreasing the capacity of dam). The present research carried out on Kalan dam watershed in Malayer to distinguish the effective factors in the mass movement and recognize prepared areas for mass movement and appointing the weight which states the standard role of these factors in mass movement occurrence. In this research, factors such as Lithology, space of faull, slop, altitudinal surfaces and rainfall are chosen as the most effective factor in the mass movement occurrence. By using geological maps. Topography and aerial photos in the from of geographical information system (GIS). And ArcGIS software, they used the LNRF model in the maps of the research in the numerical and stratum from for analyzing the obtained data through studying the effective variances as the research conceptive tools. In the end they prepared the zoning map of the mass movement dang by combining the various strata (layers) through weighting to the effective factors and their algebraic conclusion and the result show that the LNRF model is a good competence to study the data and zoning the mass movement or in the basin of Kalan dam.
