| چکیده [English] | ||
| Because of major damages caused by mass movements on human and financial resources due to increased rate of erosion in Iran, this research intended to determine factors affecting Inass movement for preventing and controlling purposes. To meet this aim, the effects of slope and aspect, as two major factors affecting mass movement, were studied in Taleghan watershed using GIS. After digitizing, overlaying, scoring, classifying and comparing of available data, the best and safest pathway between Dizan and N arian villages located on the watershed were then determined. It was attempted to determine the effects of each of the above-mentioned factors on mass movement exclusively on sulifloxion. However, the results showed that there is another factor playing the role of aspect factor. Finally, after studying other factors, it was found that active faults and over thrusts play more extensive roles on sulifloxion than aspect in mass movements. In addition, the results showed that the most vulnerable slopes for mass movements were classes III and V (i.e., 10-25% and 40-60% slopes, respectively), but for other slopes (outside these two classes), mass movement decreases. | ||
