Abstract

Recognition of effective factor in mass movements occurrence and mass movements HAZARD ZONATION is one of the most important measures in prevention and reduction of their hazards. In this research FLOW AND CHANALLIZED FLOW HAZARD ZONATION was done in Damavand Drainage Basin with 761 km2 area, located in Southern Albours Mountains with using quantitative method. For doing this, first, FLOW AND CHANALLIZED FLOW inventory map of the area which was prepared using air photos with the scale of 1:20000 and 1:50000 and field works, was used. In this map 56 flow, 26 chanallized flow and the total of 82 movements were shown. In this research, the effective factors for FLOW AND CHANALLIZED FLOW occurrence were recognized to be as follows: land use, geological formation, rainfall, slope, aspect and elevation. Then by using FLOW AND CHANALLIZED FLOW inventory map and quantification of effective factor in mass movements occurrence, mass movements HAZARD ZONATION was done in the area by giving percentages to each sub factor of above-mentioned factors. This process was done by extensional facilities of Arcview which is called "Extension Spatial Analyst". The raster maps of six factors with cellular resolution of. /0014 meters, for FLOW AND CHANALLIZED FLOW were added together, in order to obtain HAZARD ZONATION of each movement. For evaluation of HAZARD ZONATION accuracy and separation ability of the used method, FLOW AND CHANALLIZED FLOW HAZARD ZONATION maps were overlaid with vector maps of FLOW AND CHANALLIZED FLOW inventory maps.
