Usage of GIS InEngineering Geology

   General:
     Actually ,the first step of optimum management of the engineering equiprnentsand the
constructed structures by the human;such as damrns bridgcs,road construction projects
.etc,is reconnaissence of the region sesitive to the land sliding,to control the damages.
unstability,detachments and slides across the slopes are the most essential morphological
accidents and occurences, in which several various covcring,tectonics etc. play roles, which that the intensity of each factor ellection in this geomorphological phenomena are important when preparing the zonation maps of geological hazards map.
In study area (central of Alborz.) most of expcrienccd land slide hazards has happened in less resslance geological units.
From salistic investigation in study area by using GIS shows us that which location is able to Land slide hazards,therefbre,this can help tis in next decision making and planning.
