abstract this survey accomplished for asessment and mechanism recognition of chenaran watershed landslide effective factors and its zonation based via lim model. primarily recognized effective factors, through studing and field survey and evaluated by landslide index method(lim) then based on their weight in model, landslide hazard zonation was done.then evaluated this model competence in zonat...

nowadays, occurrence of mass movement in the northern forests ofiran, especially in the golestan province is turning to be a usual phenomenon. because of decay of vegetation cover, prediction of landslide occurrence will prevent its damages. landslide hazard zonation is a suitable way in this case. selection of the best model is a way to decrease costs and time. consequently, land slide hazard ...

it is very important to recognize the areas with high potential risk of landslide in order to resist that. in a case study, thirty three landslides have been observed in safarood watershed. the purpose of this study is to recognize factors and zonation of potential areas for landslide. this paper covers specific factors including lithology, fault, height, slope, direction, rainfall, soil, veget...

more than 30% of iran's land is formed from mountainous areas. so each year, landslides cause damages to structures, residential areas and forests, creating sedimentation, muddy floods and finally deposit the sediments in reservoir dams. therefore, for preventing of this damages and expressing the sensitivity rate of hillslopes, landslide hazard zonation is considered in prone areas. the p...

This paper presents a new approach of landslides zonation hazard studies, based on an integrated study of structural data along with geomorphological and external factors, in a hilly regions of Brazil, covered by a tropical humid rain-forest, called Serra do Mar. The Serra do Mar consists of a hilly region along the east coast of Brazil, with high slopes and many geological structures in a gnei...
